The answer is the same: do read the R Data Import/Export Manual.

But immediately:

You need a:/xx.dat or a:\\xx.dat (do read the FAQs)

Which version of R is this? The latest released version, 1.3.0,
given you a meesage about what the row numbers were before that message,
and you should heed (and quote) all the messages you get.

You probably need to set a separator, e.g. sep="\t".

I hope your 62 variables are all on one line, as read.table cannot
read multi-line records, as the help page clearly states.

    file: the name of the file which the data are to be read from. Each
          row of the table appears as one line of the file.  If it does
