Download logs from the RStudio CRAN mirror

RStudio publishes the download logs from their CRAN package mirror daily at http://cran-logs.rstudio.com.

This R package queries a database that contains the daily download numbers for each package.

Installation

You can install cranlogs from Github:

library(devtools)
install_github("metacran/cranlogs")

#> Downloading github repo metacran/cranlogs@master
#> Installing cranlogs
#> '/Library/Frameworks/R.framework/Resources/bin/R' --vanilla CMD INSTALL  \
#>   '/private/var/folders/ws/7rmdm_cn2pd8l1c3lqyycv0c0000gn/T/RtmpPkIqt7/devtools1b982d42cb22/metacran-cranlogs-e4aab96'  \
#>   --library='/Users/gaborcsardi/r_pkgs' --install-tests

Usage

It has a very simple API. By default it shows the total number of package downloads from the previous day.

library(cranlogs)
cran_downloads()

#>         date  count
#> 1 2015-05-06 395385

The last week, or the last month can be also easily queried:

cran_downloads(when = "last-week")

#>         date  count
#> 1 2015-04-30 425306
#> 2 2015-05-01 277160
#> 3 2015-05-02 211458
#> 4 2015-05-03 253502
#> 5 2015-05-04 389516
#> 6 2015-05-05 418476
#> 7 2015-05-06 395385

The package argument queries a specific package:

cran_downloads(when = "last-week", package = c("magrittr", "dplyr"))

#>          date count  package
#> 1  2015-04-30  3793 magrittr
#> 2  2015-05-01  3285 magrittr
#> 3  2015-05-02  2202 magrittr
#> 4  2015-05-03  2637 magrittr
#> 5  2015-05-04  5339 magrittr
#> 6  2015-05-05  6409 magrittr
#> 7  2015-05-06  6938 magrittr
#> 8  2015-04-30  2297    dplyr
#> 9  2015-05-01  1878    dplyr
#> 10 2015-05-02  1017    dplyr
#> 11 2015-05-03  1615    dplyr
#> 12 2015-05-04  2264    dplyr
#> 13 2015-05-05  2397    dplyr
#> 14 2015-05-06  2413    dplyr

Alternative intervals can also be specified:

cran_downloads(package = "plyr", from = "2014-01-01", to = "2014-02-01")

#>          date count package
