In crandatapkgs: Find Data-Only Packages on CRAN

CRAN Data-only Packages

This package provides a simple function that lists data-only packages (or those primarily offering built-in datasets) that are available on CRAN. It does this by subsetting the output of avaialable.packages() to return a data.frame of known data-heavy and data-only packages.

To retrieve a data.frame listing of these known packages in R, simply do:

library("crandatapkgs")
options(repos = c("https://cloud.r-project.org"))
a <- available_data()

# data structure returned by `available_data()`
str(a)

## 'data.frame':    98 obs. of  5 variables:
##  $ Package        : chr  "agridata" "alr3" "alr4" "aplore3" ...
##  $ Version        : chr  NA "2.0.5" "1.0.5" "0.7" ...
##  $ License        : chr  NA "GPL (>= 2)" "GPL (>= 2)" "GPL-3" ...
##  $ Type           : chr  "Data" "Supplement" "Supplement" "Supplement" ...
##  $ DataDescription: chr  "Agriculture" "" "" "" ...

# a few packages from the response
a[1:3,]

##    Package Version    License       Type DataDescription
## 1 agridata    <NA>       <NA>       Data     Agriculture
## 2     alr3   2.0.5 GPL (>= 2) Supplement                
## 3     alr4   1.0.5 GPL (>= 2) Supplement

Contributing Known Packages

New packages can be added by creating a GitHub pull request that edits the packages comma-separated values file and adding a row for a package in the form of:

PackageName,Type,"Data Description"

where Type is either Data (for data-only packages) or Supplement (for packages that provide data supplements to other packages or texts). Data Description should be a double-quoted description of the kind of data found in the package.

Installation

The package is available on CRAN and can be installed directly in R using:
