Hello Melissa,
First of all, you need a descriptive subject, such as, "Cannot read
tabular data in R". R-help is a high-volume (100 to 200 messages per
day) and each person that can help you is a specialist in one or
another area.
Secondly, please include in your mail an excerpt of the relevant code
you used that read the data in and produced the error.
