[R] Error in file(file, "r")

[Chisolm, Barbara]

Hello,

I am a new user of R, and I am not able to read/scan external files.  I am
working in a Linux environment.  I have read through the R FAQ and documents
and have not been successful using the recommendations.  Below are several
scripts I've used and the error messages. .  

I've cc'd Brandon Whitcher because it was recommended in another FAQ.   I
read that this is a bug that occurs on Windows.   Is there is a patch/fix
that I can use?  I'd appreciate any help with this problem.

Thnx,
Barbara Chisolm
