[R-pkg-devel] Help with Package creation

[Jennifer Bryan]

Hi Mohammad,

You don’t really say but I’m guessing your error is when checking the package?

I think you should take the message at face value. It appears the randomForest package is not
available from the libraries R knows about at the time of whatever it is your doing. R CMD check
will not go out and install a dependency for you. install.packages() will do this, so maybe that
is what you’re thinking of.
