Its not likely that there are errors in this software so
its probably not a mistake but some other cause.

Read the posting guide at  the bottom of each post.
In particular, cut down the input file to a few lines that
still exhibit the problem in order to provide a reproducible 
example. 

As an aside note that 'header = TRUE' is the default in read.csv
(but not on read.table) so you don't need to specify it.
