Question

In r, Find the number of plot methods that are in your version of R

Answer 1

Version() provides detailed information about the version of R running. R. version is a variable (a list ) holding this information (and version is a copy of it for S compatibility).

Open RStudio. At the top of the Console you will see session info. The first line tells you which version of R you are using. If RStudio is already open and you're deep in a session, type R.

require(graphics)

R.version$os # to check how lucky you are ...
plot(0) # any plot
mtext(R.version.string, side = 1, line = 4, adj = 1) # a useful bottom-right note

## a good way to detect macOS:
if(grepl("^darwin", R.version$os)) message("running on macOS")

## Short R version string, ("space free", useful in file/directory names;
##                          also fine for unreleased versions of R):
shortRversion <- function() {
   rvs <- R.version.string
   if(grepl("devel", (st <- R.version$status)))
       rvs <- sub(paste0(" ",st," "), "-devel_", rvs, fixed=TRUE)
   gsub("[()]", "", gsub(" ", "_", sub(" version ", "-", rvs)))
}
shortRversion()
