Hello all.
I'm building a package where I want to include a function from two
different packages. In particular, I want to include mvrnorm and
hyperg_2F1 from MASS and gsl, respectively (but the specific functions
do not matter). With what I've tried after reading the "Specifying
imports and exports" section from the "Writing R Extensions"
manual, I
get an error: "Namespace dependencies not required."
My NAMESPACE file consists of the following:
importFrom(MASS, mvrnorm)
importFrom(gsl, hyperg_2F1)
exportPattern("^[^\\.]")
A completely separate issue is that when running check, I get a warning
at the "checking S3 generic/method consistency" line that states:
"Warning: use of NULL environment is depreciated." I've looked at
the
"Generic functions and methods" in the Writing R Extensions manual and
I'm still not sure what the "use of NULL environment is
depreciated." I
suppose this is not a big deal, but it seems best not to have any warnings.
I'm sure I'm just missing something simple on both of these issues. Any
insight would be appreciated. I'm building the package with Win. XP.
Thanks,
Ken

The message is probably not to do with that topic but to do with loading your package. So can you install and load the package without any messages?> I'm sure I'm just missing something simple on both of these issues. Any > insight would be appreciated.

The next version will not. From the location where you saw the error, it looks like a bug in R rather than in your code, but surely such a thing would have been seen before. Are you using an unreleased version? This may also explain the problems with your namespace file. Duncan Murdoch> > > I'm sure I'm just missing something simple on both of these issues.
