...tag: AN, HA, etc. Is there a way to parse text data in R? In excel, I would have used the "left" and "right" function to cut out just the middle two letters out and put into another column to sort by. Thanks! -- View this message in context: http://www.nabble.com/Text-data-tp21714334p21714334.html Sent from the R help mailing list archive at Nabble.com.

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems
