Dear Patrick,

It's hard to know how to help since you provide very little specific
information. For example, what OS are you using -- Windows, Mac OS,

Packages such as sem have to be installed before they are usable, and
even then ?sem won't provide you with information before the package is
loaded via library(sem).

You might start by reading the Introduction to R manual that comes with
R. Among other things, it explains how to install packages. Under
Windows, for example, the easiest way to proceed if you have an active
Internet connection is via the "Packages -> Install package(s)" menu in
the R console.

I hope this helps,
