)

Arguments

`pkgs`	Package name(s). Default is "all", which prints statistics for all rOpenGov packages. You can also input 1 or more package names as a vector.
`output`	"tibble" (default) or "plot". With sum "by_month" and "by_year" "plot" outputs a line chart, with "total" it outputs a bar chart.
`sum`	"by_month" (default), "by_year" or "total"

Details

This function is intended for easy retrieval and visualization of rOpenGov package download statistics from CRAN. It is an evolution of an R script by antagomir. As such it retains some features that were present in the original R script and were deemed useful for rOpenGov's internal use. This function may or may not be useful in other instances.

Value

tibble or a ggplot2 line chart or a bar chart
