tail a file in R

Greetings,

not sure tail in R can tail a file as documented here
http://rss.acs.unt.edu/Rdoc/library/R.basic/html/tail.html

but when I tried my R version 2.14.2 it doesn't work.


I need to tail many files to see if appending operations need to be
performed on them..

Thanks!
Jim.
