In crandep: Network Analysis of Dependencies of CRAN Packages
crandep
The goal of crandep is to provide functions for analysing the
dependencies of CRAN packages using social network analysis.
Installation
You can install crandep from github with:
# install.packages("devtools")
devtools::install_github("clement-lee/crandep")
library(crandep)
library(dplyr)
library(ggplot2)
library(igraph)
Overview
The functions and example dataset can be divided into the following
categories:
- For obtaining data frames of package dependencies, use
get_dep(),
get_dep_all_packages().
- For obtaining igraph objects of package dependencies, use
get_graph_all_packages() and df_to_graph().
- For modelling the number of dependencies, use
*pol() and
*mix2().
- There is also an example data set
cran_dependencies.
One or multiple types of dependencies
To obtain the information about various kinds of dependencies of a
package, we can use the function get_dep() which takes the package
name and the type of dependencies as the first and second arguments,
respectively. Currently, the second argument accepts a character vector
of one or more of the following words: Depends, Imports,
LinkingTo, Suggests, Enhances, Reverse_depends,
Reverse_imports, Reverse_linking_to, Reverse_suggests, and
Reverse_enhances, or any variations in their letter cases, or if the
underscore "_" is replaced by a space.
get_dep("dplyr", "Imports")

#> 10 dplyr tibble imports FALSE
#> 11 dplyr tidyselect imports FALSE
#> 12 dplyr utils imports FALSE
#> 13 dplyr vctrs imports FALSE
get_dep("MASS", c("depends", "suggests"))
#> from to type reverse
#> 1 MASS grDevices depends FALSE
#> 2 MASS graphics depends FALSE
#> 3 MASS stats depends FALSE
#> 4 MASS utils depends FALSE
#> 5 MASS lattice suggests FALSE
#> 6 MASS nlme suggests FALSE
#> 7 MASS nnet suggests FALSE
#> 8 MASS survival suggests FALSE
For more information on different types of dependencies, see the
official
guidelines
and https://r-pkgs.org/description.html.
In the output, the column type is the type of the dependency converted
to lower case. Also, LinkingTo is now converted to linking to for
consistency.
get_dep("xts", "LinkingTo")
#> from to type reverse
#> 1 xts zoo linking to FALSE
get_dep("xts", "linking to")
#> from to type reverse
#> 1 xts zoo linking to FALSE
For the reverse dependencies, instead of including the prefix “Reverse”
in type, we use the argument reverse:
get_dep("abc", c("depends", "depends"), reverse = TRUE)
#> from to type reverse
#> 1 abc abctools depends TRUE
#> 2 abc EasyABC depends TRUE
get_dep("xts", c("linking to", "linking to"), reverse = TRUE)
#> from to type reverse
#> 1 xts ichimoku linking to TRUE
#> 2 xts RcppXts linking to TRUE
#> 3 xts TTR linking to TRUE
Theoretically, for each forward dependency
#> from to type reverse
#> 1 A B c FALSE
there should be an equivalent reverse dependency
#> from to type reverse
#> 1 B A c TRUE
Aligning the type in the forward dependency and the reverse dependency
enables this to be checked easily.
To obtain all types of dependencies, we can use "all" in the second
argument, instead of typing a character vector of all words:
df0.rstan <- get_dep("rstan", "all")
dplyr::count(df0.rstan, type)
#> type n
#> 1 depends 1
#> 2 imports 10
#> 3 linking to 5
#> 4 suggests 12
df1.rstan <- get_dep("rstan", "all", reverse = TRUE) # too many rows to display
dplyr::count(df1.rstan, type) # hence the summary using count()
#> type n
#> 1 depends 20
#> 2 enhances 3
#> 3 imports 139
#> 4 linking to 120
#> 5 suggests 33
As of 2024-08-02, there are 0 packages that have all 10 types of
dependencies, and 6 packages that have 9 types of dependencies: Matrix,
bigmemory, miceadds, quanteda, rstan, xts.
Building and visualising a dependency network
To build a dependency network, we have to obtain the dependencies for
multiple packages. For illustration, we choose the core packages of the
tidyverse, and find out what each
package Imports. We put all the dependencies into one data frame, in
which the package in the from column imports the package in the to
column. This is essentially the edge list of the dependency network.
df0.imports <- rbind(
get_dep("ggplot2", "Imports"),
get_dep("dplyr", "Imports"),
get_dep("tidyr", "Imports"),
get_dep("readr", "Imports"),
get_dep("purrr", "Imports"),
get_dep("tibble", "Imports"),
get_dep("stringr", "Imports"),
get_dep("forcats", "Imports")
)
head(df0.imports)
#> from to type reverse
#> 1 ggplot2 cli imports FALSE
#> 2 ggplot2 glue imports FALSE
#> 3 ggplot2 grDevices imports FALSE
#> 4 ggplot2 grid imports FALSE
#> 5 ggplot2 gtable imports FALSE
#> 6 ggplot2 isoband imports FALSE
tail(df0.imports)
#> from to type reverse
#> 73 forcats cli imports FALSE
#> 74 forcats glue imports FALSE
#> 75 forcats lifecycle imports FALSE
#> 76 forcats magrittr imports FALSE
#> 77 forcats rlang imports FALSE
#> 78 forcats tibble imports FALSE
All types of dependencies, in a data frame
The example dataset cran_dependencies contains all dependencies as of
2020-05-09.
data(cran_dependencies)
cran_dependencies
#> # A tibble: 211,381 × 4
#> from to type reverse
#> <chr> <chr> <chr> <lgl>
#> 1 A3 xtable depends FALSE
#> 2 A3 pbapply depends FALSE
#> 3 A3 randomForest suggests FALSE
#> 4 A3 e1071 suggests FALSE
#> 5 aaSEA DT imports FALSE
#> 6 aaSEA networkD3 imports FALSE
#> 7 aaSEA shiny imports FALSE
#> 8 aaSEA shinydashboard imports FALSE
#> 9 aaSEA magrittr imports FALSE
#> 10 aaSEA Bios2cor imports FALSE
#> # ℹ 211,371 more rows
dplyr::count(cran_dependencies, type, reverse)
#> # A tibble: 8 × 3
#> type reverse n
#> <chr> <lgl> <int>
#> 1 depends FALSE 11123
#> 2 depends TRUE 9672
#> 3 imports FALSE 57617
#> 4 imports TRUE 51913
#> 5 linking to FALSE 3433
#> 6 linking to TRUE 3721
#> 7 suggests FALSE 35018
#> 8 suggests TRUE 38884
This is essentially a snapshot of CRAN. We can obtain all the current
dependencies using get_dep_all_packages(), which requires no
arguments:
df0.cran <- get_dep_all_packages()
head(df0.cran)
#> from to type reverse
#> 3 AATtools magrittr imports FALSE
#> 4 AATtools dplyr imports FALSE
#> 5 AATtools doParallel imports FALSE
#> 6 AATtools foreach imports FALSE
#> 7 ABACUS ggplot2 imports FALSE
#> 8 ABACUS shiny imports FALSE
dplyr::count(df0.cran, type, reverse) # numbers in general larger than above
#> type reverse n
#> 1 depends FALSE 10525
#> 2 depends TRUE 9097
#> 3 enhances FALSE 638
#> 4 enhances TRUE 652
#> 5 imports FALSE 103771
#> 6 imports TRUE 95407
#> 7 linking to FALSE 5872
#> 8 linking to TRUE 6273
#> 9 suggests FALSE 65414
#> 10 suggests TRUE 72346
Network of one type of dependencies, as an igraph object
We can build dependency network using get_graph_all_packages().
Furthermore, we can verify that the forward and reverse dependency
networks are (almost) the same, by looking at their size (number of
edges) and order (number of nodes).
g0.depends <- get_graph_all_packages(type = "depends")
g0.depends
#> IGRAPH 4c9c1ff DN-- 4627 7491 --
#> + attr: name (v/c)
#> + edges from 4c9c1ff (vertex names):
#> [1] A3 ->xtable A3 ->pbapply
#> [3] abc ->abc.data abc ->nnet
#> [5] abc ->quantreg abc ->MASS
#> [7] abc ->locfit ABCp2 ->MASS
#> [9] abctools ->abc abctools ->abind
#> [11] abctools ->plyr abctools ->Hmisc
#> [13] abd ->nlme abd ->lattice
#> [15] abd ->mosaic abodOutlier->cluster
#> + ... omitted several edges
We could obtain essentially the same graph, but with the direction of
the edges reversed, by specifying type = "reverse depends":
# Not run
g0.rev_depends <- get_graph_all_packages(type = "depends", reverse = TRUE)
g0.rev_depends
The dependency words accepted by the argument type is the same as in
get_dep(). The two networks’ size and order should be very close if
not identical to each other. Because of the dependency direction, their
edge lists should be the same but with the column names from and to
swapped.
For verification, the exact same graphs can be obtained by filtering the
data frame for the required dependency and applying df_to_graph():
g1.depends <- df0.cran |>
dplyr::filter(type == "depends" & !reverse) |>
df_to_graph(nodelist = dplyr::rename(df0.cran, name = from))
g1.depends # same as g0.depends
#> IGRAPH 0cb388d DN-- 4627 7491 --
#> + attr: name (v/c), type (e/c), reverse (e/l)
#> + edges from 0cb388d (vertex names):
#> [1] A3 ->xtable A3 ->pbapply
#> [3] abc ->abc.data abc ->nnet
#> [5] abc ->quantreg abc ->MASS
#> [7] abc ->locfit ABCp2 ->MASS
#> [9] abctools ->abc abctools ->abind
#> [11] abctools ->plyr abctools ->Hmisc
#> [13] abd ->nlme abd ->lattice
#> [15] abd ->mosaic abodOutlier->cluster
#> + ... omitted several edges

Network of one type of dependencies, as an igraph object
We can build dependency network using get_graph_all_packages().
Furthermore, we can verify that the forward and reverse dependency
networks are (almost) the same, by looking at their size (number of
edges) and order (number of nodes).
g0.depends <- get_graph_all_packages(type = "depends")
g0.depends
#> IGRAPH 4c9c1ff DN-- 4627 7491 --
#> + attr: name (v/c)

#> [11] abctools ->plyr abctools ->Hmisc
#> [13] abd ->nlme abd ->lattice
#> [15] abd ->mosaic abodOutlier->cluster
#> + ... omitted several edges
We could obtain essentially the same graph, but with the direction of
the edges reversed, by specifying type = "reverse depends":
# Not run
g0.rev_depends <- get_graph_all_packages(type = "depends", reverse = TRUE)
g0.rev_depends
The dependency words accepted by the argument type is the same as in
get_dep(). The two networks’ size and order should be very close if
not identical to each other. Because of the dependency direction, their
edge lists should be the same but with the column names from and to
swapped.
For verification, the exact same graphs can be obtained by filtering the
