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.

None, save the file, and use the following function to read your data
into a data.frame:
read.delim("smokedata.txt")
This assumes you used a tab character between each field.
HTH, Edwin
