Well .... perhaps. I asked to see the first several lines of the data. If it
really were a csv file, then there should not have been any commas in the first
column when the R data-object was printed. Any spaces in the header row should
have been converted to periods. That's what the `make.names` function does when
it encounters spaces or special characters.
