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. >From looking at your text file, I would delete the white space before 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.
