Hello,
I was wondering if anyone has a way to test if a package is currently being
installed. My solution was to check if environment variable
"R_INSTALL_PKG"
was unset, something like:
"R CMD INSTALL-ing" <- function ()
!is.na(Sys.getenv("R_INSTALL_PKG", NA))
Unfortunately, I couldn't find what I was looking for with
?"environment
variables". So if anyone has any better methods, I'd be happy to hear
them,
thank you!

Does ?installed.packages help?

I believe that no code from the package is executed during a binary install: it just copies files into the appropriate places. Duncan
