I am guessing that you are just looking for help(package = caTools)
, which will open your browser to the relevant help page that lists all the functions in the "caTools" package.
You can also try: library(help = caTools)
, but that doesn't seem to capture everything. The nice thing about this latter approach is that you can capture the output in case you needed to refer to it somewhere else:
x <- library(help = caTools)
x$info[[2]]

# [2] "base64encode Convert R vectors to/from the Base64 format"
