[R] geepack installation problem?

[Denis B]

Hello R Forum members.

I have installed for my statistician user, apparently without error, both
the concord and geepack packages.   The target system is R 2.10.1 on a
64-bit RedHat Enterprise Linux platform.

However when she attempts to invoke a function in geepack, for example...

geeglm((abuse_total ~ case),id=mother, family="poisson")

the resultant error is

Error: could not find function "geeglm"

Neither she as a user, nor myself as administrator, can get even help to
work for geepack.  It is almost as though the package is not installed,
regardless that the installation process appeared to complete without error.

I would be grateful of some guidance for her.   I have tried this (R +
geepack) on another Linux-based system (SuSE Enterprise Linux, also 64-bit)
with identical results and I do not see any references to similar issues in
amongst R Forum articles.

Kind regards,
Denis
