Converting data from a non-R format to R's internal format is a common
place to run into errors. Use the str() function to examine any data you
read in to make sure R is seeing it the way that you expect. If that looks ok
try using summary() or plot() for more checks that the data import went
as expected. Do this before doing any other analysis on the data and you
will avoid a lot of errors later on.
E.g., str(dat) shows that column "A" is character, as are several other columns
that you probably mean to be numeric, which would account for the error
message that you got.
(The output of dput() got mangled a bit in the mail (long lines got broken
in inappropriate places), but I think I got it read in corrrectly.)
