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/RtmpjEx0oD/devtools17e7c1e2f982c/metacran-cranlogs-10e40e8' \
#> --library='/Library/Frameworks/R.framework/Versions/3.2/Resources/library' \
#> --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
#> 32 2014-01-01 0 plyr
