I think that command should work (assuming that it is *comma* rather
than semi-colon delimited, which is used in countries where a comma is
used as a decimal point, in which case you should use read.csv2
instead).  So,  is your data definitely as clean as you think. Have
you looked at the data in a text editor?  What are the dimensions of
the resulting data frame?
