)

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.

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
