I am a newbie to R. I can not figure out how to compute Ln(x) value in R.
My question may be so easy for you but I will really appreciate if you can
help me. Thanks so much for your time!

This is in regards to the SNOW library.

Do you have some symbolic links that make loops in your file system?
list.files() has problems with such loops and find does not. E.g., on a Linux
box:
% cd /tmp
% mkdir dir dir/subdir

% ln -s ../../dir linkToUpperDir
% cd /tmp
