In r-hub/pkgsearch: Search and Query CRAN R Packages
Search and Query CRAN R Packages
pkgsearch uses R-hub web services that munge CRAN metadata and let you
access it through several lenses.
Installation
Install the latest pkgsearch release from CRAN:
install.packages("pkgsearch")
The development version is on GitHub:
pak::pak("r-hub/pkgsearch")
Usage
Search relevant packages
Do you need to find packages solving a particular problem, e.g.
“permutation test”?
library("pkgsearch")
library("pillar") # nicer data frame printing
pkg_search("permutation test")

#> 1 Rcpp @ 1.0.12 Dirk Eddelbuettel, 3 months ago
#> ---------------
#> # Seamless R and C++ Integration
#> The 'Rcpp' package provides R functions as well as C++ classes which offer a
#> seamless integration of R and C++. Many R data types and objects can be mapped
#> back and forth to C++ equivalents which facilitates both writing of new code
#> as well as easier integration of third-party libraries. Documentation about
#> 'Rcpp' is provided by several vignettes included in this package, via the
#> 'Rcpp Gallery' site at <https://gallery.rcpp.org>, the paper by Eddelbuettel
#> and Francois (2011, <doi:10.18637/jss.v040.i08>), the book by Eddelbuettel
#> (2013, <doi:10.1007/978-1-4614-6868-4>) and the paper by Eddelbuettel and
#> Balamuta (2018, <doi:10.1080/00031305.2017.1375990>); see 'citation("Rcpp")'
#> for details.

#> 2 BH @ 1.84.0.0 Dirk Eddelbuettel, 3 months ago
#> ---------------
#> # Boost C++ Header Files
#> Boost provides free peer-reviewed portable C++ source libraries. A large part
#> of Boost is provided as C++ template code which is resolved entirely at
#> compile-time without linking. This package aims to provide the most useful
#> subset of Boost libraries for template use among CRAN packages. By placing
#> these libraries in this package, we offer a more efficient distribution system
#> for CRAN as replication of this code in the sources of other packages is
#> avoided. As of release 1.84.0-0, the following Boost libraries are included:
#> 'accumulators' 'algorithm' 'align' 'any' 'atomic' 'beast' 'bimap' 'bind'
#> 'circular_buffer' 'compute' 'concept' 'config' 'container' 'date_time'
#> 'detail' 'dynamic_bitset' 'exception' 'flyweight' 'foreach' 'functional'
#> 'fusion' 'geometry' 'graph' 'heap' 'icl' 'integer' 'interprocess' 'intrusive'
#> 'io' 'iostreams' 'iterator' 'lambda2' 'math' 'move' 'mp11' 'mpl'
#> 'multiprecision' 'numeric' 'pending' 'phoenix' 'polygon' 'preprocessor'
#> 'process' 'propery_tree' 'qvm' 'random' 'range' 'scope_exit' 'smart_ptr'
#> 'sort' 'spirit' 'tuple' 'type_traits' 'typeof' 'unordered' 'url' 'utility'
#> 'uuid'.

#>
#> 4 SnowballC @ 0.7.1 Milan Bouchet-Valat, about a year ago
#> -------------------
#> # Snowball Stemmers Based on the C 'libstemmer' UTF-8 Library
#> An R interface to the C 'libstemmer' library that implements Porter's word
#> stemming algorithm for collapsing words to a common root to aid comparison of
#> vocabulary. Currently supported languages are Arabic, Basque, Catalan, Danish,
#> Dutch, English, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian,
#> Irish, Italian, Lithuanian, Nepali, Norwegian, Portuguese, Romanian, Russian,
#> Spanish, Swedish, Tamil and Turkish.
#> https://github.com/nalimilan/R.TeMiS
#>
#> 5 glpkAPI @ 1.3.4 Mihail Anton, about a year ago
#> -----------------
#> # R Interface to C API of GLPK
#> R Interface to C API of GLPK, depends on GLPK Version >= 4.42.
#>
#> 6 RcppProgress @ 0.4.2 Karl Forner, 4 years ago
#> ----------------------
#> # An Interruptible Progress Bar with OpenMP Support for C++ in R Packages
#> Allows to display a progress bar in the R console for long running
#> computations taking place in c++ code, and support for interrupting those
#> computations even in multithreaded code, typically using OpenMP.
#> https://github.com/kforner/rcpp_progress
#>
#> 7 getopt @ 1.20.4 Trevor L Davis, 7 months ago
#> -----------------
#> # C-Like 'getopt' Behavior
#> Package designed to be used with Rscript to write '#!' shebang scripts that
#> accept short and long flags/options. Many users will prefer using instead the
#> packages optparse or argparse which add extra features like automatically
#> generated help option and usage, support for default values, positional
#> argument support, etc.
#> https://github.com/trevorld/r-getopt
#>
#> 8 boot @ 1.3.30 Alessandra R. Brazzale, 2 months ago
#> ---------------
#> # Bootstrap Functions (Originally by Angelo Canty for S)
#> Functions and datasets for bootstrapping from the book "Bootstrap Methods and
#> Their Application" by A. C. Davison and D. V. Hinkley (1997, CUP), originally
#> written by Angelo Canty for S.
#>
#> 9 LiblineaR @ 2.10.23 Thibault Helleputte, 4 months ago
#> ---------------------
#> # Linear Predictive Models Based on the LIBLINEAR C/C++ Library
#> A wrapper around the LIBLINEAR C/C++ library for machine learning (available
#> at <https://www.csie.ntu.edu.tw/~cjlin/liblinear/>). LIBLINEAR is a simple
#> library for solving large-scale regularized linear classification and
#> regression. It currently supports L2-regularized classification (such as
#> logistic regression, L2-loss linear SVM and L1-loss linear SVM) as well as
#> L1-regularized classification (such as L2-loss linear SVM and logistic
#> regression) and L2-regularized support vector regression (with L1- or
#> L2-loss). The main features of LiblineaR include multi-class classification
#> (one-vs-the rest, and Crammer & Singer method), cross validation for model
#> selection, probability estimates (logistic regression only) or weights for
#> unbalanced data. The estimation of the models is particularly fast as compared
#> to other libraries.
#> <https://dnalytics.com/software/liblinear/>
#>
#> 10 lme4 @ 1.1.35.3 Ben Bolker, 6 days ago
#> ------------------
#> # Linear Mixed-Effects Models using 'Eigen' and S4
#> Fit linear and generalized linear mixed-effects models. The models and their
#> components are represented using S4 classes and methods. The core
#> computational algorithms are implemented using the 'Eigen' C++ library for
#> numerical linear algebra and 'RcppEigen' "glue".

Stemming
The search server uses the stems of the words in the indexed metadata,
and the search phrase. This means that “colour” and “colours” deliver
the exact same result. So do “coloring”, “colored”, etc. (Unless one is
happen to be an exact package name or match another non-stemmed field.)
ps("colour", size = 3)
#> - "colour" ---------------------------------------------- 329 packages in 0.021 seconds -

Ranking
The most important feature of a search engine is the ranking of the
results. The best results should be listed first. pkgsearch uses
weighted scoring, where a match in the package title gets a higher score
than a match in the package description. It also uses the number of
reverse dependencies and the number of downloads to weight the scores:
ps("colour")[, c("score", "package", "revdeps", "downloads_last_month")]
#> # A data frame: 10 × 4
#> score package revdeps downloads_last_month
#> <dbl> <chr> <int> <int>
#> 1 6717. colorspace 71 1
#> 2 3442. shape 19 1
#> 3 2490. dichromat 7 1
#> 4 2110. RColorBrewer 130 1
#> 5 1632. crayon 3 1
#> 6 1631. colorRamps 3 1
#> 7 1546. colorizer 1 1
#> 8 1496. munsell 3 1
#> 9 1463. colouR 1 1
#> 10 1457. plotrix 62 1
Preferring Phrases
The search engine prefers matching whole phrases over single words. E.g.
the search phrase “permutation test” will rank coin higher than
testthat, even though testthat is a much better result for the single
word “test”. (In fact, at the time of writing testthat is not even on
the first page of results.)
ps("permutation test")
#> - "permutation test" ----------------------------------- 2545 packages in 0.048 seconds -
#> # package version by @ title
#> 1 100 coin 1.4.3 Torsten Hothorn 7M Conditional Inference Procedures ...

If the whole phrase does not match, pkgsearch falls back to individual
matching words. For example, a match from either words is enough here,
to get on the first page of results:

British vs American English
The search engine uses a dictionary to make sure that package metadata
and queries given in British and American English yield the same
results. E.g. note the spelling of colour/color in the results:

Ascii Folding
Especially when searching for package maintainer names, it is convenient
to use the corresponding ASCII letters for non-ASCII characters in
search phrases. E.g. the following two queries yield the same results.
Note that case is also ignored.

#> 1 Rcpp @ 1.0.12 Dirk Eddelbuettel, 3 months ago
#> ---------------
#> # Seamless R and C++ Integration
#> The 'Rcpp' package provides R functions as well as C++ classes which offer a
#> seamless integration of R and C++. Many R data types and objects can be mapped
#> back and forth to C++ equivalents which facilitates both writing of new code
#> as well as easier integration of third-party libraries. Documentation about
#> 'Rcpp' is provided by several vignettes included in this package, via the
#> 'Rcpp Gallery' site at <https://gallery.rcpp.org>, the paper by Eddelbuettel
#> and Francois (2011, <doi:10.18637/jss.v040.i08>), the book by Eddelbuettel
#> (2013, <doi:10.1007/978-1-4614-6868-4>) and the paper by Eddelbuettel and
#> Balamuta (2018, <doi:10.1080/00031305.2017.1375990>); see 'citation("Rcpp")'
#> for details.

#> 2 BH @ 1.84.0.0 Dirk Eddelbuettel, 3 months ago
#> ---------------
#> # Boost C++ Header Files
#> Boost provides free peer-reviewed portable C++ source libraries. A large part
#> of Boost is provided as C++ template code which is resolved entirely at
#> compile-time without linking. This package aims to provide the most useful
#> subset of Boost libraries for template use among CRAN packages. By placing
#> these libraries in this package, we offer a more efficient distribution system
#> for CRAN as replication of this code in the sources of other packages is
#> avoided. As of release 1.84.0-0, the following Boost libraries are included:
#> 'accumulators' 'algorithm' 'align' 'any' 'atomic' 'beast' 'bimap' 'bind'
#> 'circular_buffer' 'compute' 'concept' 'config' 'container' 'date_time'
#> 'detail' 'dynamic_bitset' 'exception' 'flyweight' 'foreach' 'functional'
#> 'fusion' 'geometry' 'graph' 'heap' 'icl' 'integer' 'interprocess' 'intrusive'
#> 'io' 'iostreams' 'iterator' 'lambda2' 'math' 'move' 'mp11' 'mpl'
#> 'multiprecision' 'numeric' 'pending' 'phoenix' 'polygon' 'preprocessor'
#> 'process' 'propery_tree' 'qvm' 'random' 'range' 'scope_exit' 'smart_ptr'
#> 'sort' 'spirit' 'tuple' 'type_traits' 'typeof' 'unordered' 'url' 'utility'
#> 'uuid'.

#> https://dirk.eddelbuettel.com/code/inline.html
#>
#> 4 SnowballC @ 0.7.1 Milan Bouchet-Valat, about a year ago
#> -------------------
#> # Snowball Stemmers Based on the C 'libstemmer' UTF-8 Library
#> An R interface to the C 'libstemmer' library that implements Porter's word
#> stemming algorithm for collapsing words to a common root to aid comparison of
#> vocabulary. Currently supported languages are Arabic, Basque, Catalan, Danish,
#> Dutch, English, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian,
#> Irish, Italian, Lithuanian, Nepali, Norwegian, Portuguese, Romanian, Russian,
#> Spanish, Swedish, Tamil and Turkish.

#>
#> 5 glpkAPI @ 1.3.4 Mihail Anton, about a year ago
#> -----------------
#> # R Interface to C API of GLPK
#> R Interface to C API of GLPK, depends on GLPK Version >= 4.42.
#>
#> 6 RcppProgress @ 0.4.2 Karl Forner, 4 years ago
#> ----------------------
#> # An Interruptible Progress Bar with OpenMP Support for C++ in R Packages
#> Allows to display a progress bar in the R console for long running
#> computations taking place in c++ code, and support for interrupting those
#> computations even in multithreaded code, typically using OpenMP.
#> https://github.com/kforner/rcpp_progress
#>
#> 7 getopt @ 1.20.4 Trevor L Davis, 7 months ago
#> -----------------
#> # C-Like 'getopt' Behavior
#> Package designed to be used with Rscript to write '#!' shebang scripts that
#> accept short and long flags/options. Many users will prefer using instead the
#> packages optparse or argparse which add extra features like automatically
#> generated help option and usage, support for default values, positional
#> argument support, etc.
#> https://github.com/trevorld/r-getopt
#>
#> 8 boot @ 1.3.30 Alessandra R. Brazzale, 2 months ago
#> ---------------
#> # Bootstrap Functions (Originally by Angelo Canty for S)
#> Functions and datasets for bootstrapping from the book "Bootstrap Methods and
#> Their Application" by A. C. Davison and D. V. Hinkley (1997, CUP), originally
#> written by Angelo Canty for S.
#>
#> 9 LiblineaR @ 2.10.23 Thibault Helleputte, 4 months ago
#> ---------------------
#> # Linear Predictive Models Based on the LIBLINEAR C/C++ Library
#> A wrapper around the LIBLINEAR C/C++ library for machine learning (available
#> at <https://www.csie.ntu.edu.tw/~cjlin/liblinear/>). LIBLINEAR is a simple
#> library for solving large-scale regularized linear classification and
#> regression. It currently supports L2-regularized classification (such as
#> logistic regression, L2-loss linear SVM and L1-loss linear SVM) as well as
#> L1-regularized classification (such as L2-loss linear SVM and logistic
#> regression) and L2-regularized support vector regression (with L1- or
#> L2-loss). The main features of LiblineaR include multi-class classification
#> (one-vs-the rest, and Crammer & Singer method), cross validation for model
#> selection, probability estimates (logistic regression only) or weights for
#> unbalanced data. The estimation of the models is particularly fast as compared
#> to other libraries.
#> <https://dnalytics.com/software/liblinear/>
#>
#> 10 lme4 @ 1.1.35.3 Ben Bolker, 6 days ago
#> ------------------
#> # Linear Mixed-Effects Models using 'Eigen' and S4
#> Fit linear and generalized linear mixed-effects models. The models and their
#> components are represented using S4 classes and methods. The core
#> computational algorithms are implemented using the 'Eigen' C++ library for
#> numerical linear algebra and 'RcppEigen' "glue".

Stemming
The search server uses the stems of the words in the indexed metadata, and the search phrase. This means that “colour” and “colours” deliver the exact same result. So do “coloring”, “colored”, etc. (Unless one is happen to be an exact package name or match another non-stemmed field.)
ps("colour", size = 3)
#> - "colour" ---------------------------------------------- 329 packages in 0.021 seconds -

Ranking
The most important feature of a search engine is the ranking of the results. The best results should be listed first. pkgsearch uses weighted scoring, where a match in the package title gets a higher score than a match in the package description. It also uses the number of reverse dependencies and the number of downloads to weight the scores:
ps("colour")[, c("score", "package", "revdeps", "downloads_last_month")]
#> # A data frame: 10 × 4
#> score package revdeps downloads_last_month
#> <dbl> <chr> <int> <int>
#> 1 6717. colorspace 71 1
#> 2 3442. shape 19 1
#> 3 2490. dichromat 7 1
#> 4 2110. RColorBrewer 130 1
#> 5 1632. crayon 3 1
#> 6 1631. colorRamps 3 1
#> 7 1546. colorizer 1 1
#> 8 1496. munsell 3 1
#> 9 1463. colouR 1 1
#> 10 1457. plotrix 62 1
Preferring Phrases
The search engine prefers matching whole phrases over single words. E.g. the search phrase “permutation test” will rank coin higher than testthat, even though testthat is a much better result for the single word “test”. (In fact, at the time of writing testthat is not even on the first page of results.)
ps("permutation test")
#> - "permutation test" ----------------------------------- 2545 packages in 0.048 seconds -
#> # package version by @ title
#> 1 100 coin 1.4.3 Torsten Hothorn 7M Conditional Inference Procedures ...

If the whole phrase does not match, pkgsearch falls back to individual matching words. For example, a match from either words is enough here, to get on the first page of results:

British vs American English
The search engine uses a dictionary to make sure that package metadata and queries given in British and American English yield the same results. E.g. note the spelling of colour/color in the results:

Ascii Folding
Especially when searching for package maintainer names, it is convenient to use the corresponding ASCII letters for non-ASCII characters in search phrases. E.g. the following two queries yield the same results. Note that case is also ignored.
