R package

Query download counts directly from R with the cranlogs R package. You can install it from Github:

> devtools::install_github("metacran/cranlogs")

Then you can use it to query the CRAN logs server, and the results are returned in a data frame. You can also query multiple packages at once.

> cran_downloads(when = "last-week", packages = c("ggplot2", "httr"))
