I don't see any warnings if MASS is listed in Suggests in the DESCRIPTION.

david: I was slightly misleading about the usefulness of that link for your
question because it
doesn't explicitly talk about the case where base packages import packages.
But it talks about
the general case of importing so hopefully base handles importing just like
a package that would
be install
Hi David: According to the description on cran, lattice imports grid.
I don't know if you've seen it but www.obeautifulcode.com has a very nice
topic in its archives called "How R Searches and Finds Stuff" which is
relatde to your question that I found it to be really helpful. A lot of

Hi Davor,
To the best of my knowledge, there's only one way to use functions
from a suggested package: with require:
if (require("suggested_package")) {
function_from_suggested_package()
} else {
stop("suggested package not installed")
}
Unfortunately I don't think there's any way to use a s
If in my package "Foo" I call a function from another package "Bar" if it's
available, according to R-exts, this sounds like I should include "Suggests:
Bar" in package Foo's description. But the manual is silent on how to treat
Bar's namespace. Should I import it? If so, should this be conditio
