Vector of package names - note that unlike
other devtools functions this is the name of a CRAN
package, not a path.
libpath
path to library to store dependencies
packages - if you you're doing this a lot it's a good
idea to pick a directory and stick with it so you don't
have to download all the packages every time.
srcpath
path to directory to store source versions
of dependent packages - again, this saves a lot of time
because you don't need to redownload the packages every
time you run the package.
invisible TRUE if successful and no ERRORs or
WARNINGS,
Details
The downloaded package and check directory are only
removed if the check is successful - this allows you to
inspect the results to figure out what went wrong.
This function does not clean up after itself, but does
work in a session-specific temporary directory, so all
files will be removed when your current R session ends.
