Problem with foreign package

I tried to use write.foreign() to export to SAS this morning and got 
an error.

When I looked at the code for writeForeignSAS() I saw this line:

dfn < -df

which I think should be

dfn <- df

So, I tried to run update.packages() to see if there was an updated 
version and got the following result.

That bug was fixed a few weeks ago, but a new version has not been 
released yet.  You can get the latest source from svn:

https://svn.r-project.org/R-packages/trunk/foreign

 > update.packages(c("foreign"))

Warning message:
In list.files(lib) : list.files: 'foreign' is not a readable directory

I ran the above command as root.

Is this because the foreign package is a core package and not a CRAN one?

It is a "recommended" package, which means it is on CRAN, but is also 
included in binary distributions of R.  But the reason you got that 
error is because update.packages() doesn't take a package name as the 
first arg, the first arg is lib.loc.  You need to answer the interactive 
questions if you don't want to update everything.
