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.
You can install cranlogs from Github:
library(devtools)
install_github("metacran/cranlogs")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 2015-07-25 274520
The last week, or the last month can be also easily queried:
cran_downloads(when = "last-week")#> date count
#> 1 2015-07-19 229277
#> 2 2015-07-20 393883
#> 3 2015-07-21 377063
#> 4 2015-07-22 342425
#> 5 2015-07-23 346116
#> 6 2015-07-24 383373
#> 7 2015-07-25 274520
The package argument queries a specific package:
cran_downloads(when = "last-week", package = c("magrittr", "dplyr"))#> date count package
#> 1 2015-07-19 2230 magrittr
#> 2 2015-07-20 4019 magrittr
#> 3 2015-07-21 4146 magrittr
#> 4 2015-07-22 3865 magrittr
#> 5 2015-07-23 3908 magrittr
#> 6 2015-07-24 4065 magrittr
#> 7 2015-07-25 2329 magrittr
#> 8 2015-07-19 1058 dplyr
#> 9 2015-07-20 2107 dplyr
#> 10 2015-07-21 2137 dplyr
#> 11 2015-07-22 1904 dplyr
#> 12 2015-07-23 1931 dplyr
#> 13 2015-07-24 1814 dplyr
#> 14 2015-07-25 1068 dplyr
Alternative intervals can also be specified:
cran_downloads(package = "plyr", from = "2014-01-01", to = "2014-02-01")#> date count package
