: you can also get the PDF package documentation available on cran, e.g.
: http://cran.r-project.org/doc/packages/gregmisc.pdf
: -Greg

Also some packages, though not many, have vignettes which are documents
that describe the package as a whole as opposed to single functions.
Just issue the command:


to get a list.  Assuming you have the package strucchange 
installed, the above command will have let you know that
strucchange has a vignette called strucchange-intro which
you can view like this:


Check out the R News article on vignettes in R News 3/2 for 
more info.

In addition, its always a good idea to check if there is an 
R News article on the package.  In the case of strucchange, 
a google search for 

   rnews strucchange 

would have found a reference telling you what issue its in.
R News is found via the Newsletter link on the www.r-project.org
home page.
