Re: [R] repeating values in levels()
Thanks! I've figured out how to fix it, but how I got here is still a puzzle. :-) Cheers, Don On Sat, Oct 17, 2009 at 5:36 PM, Peter Ehlers ehl...@ucalgary.ca wrote: Donald Braman wrote: Can someone help me understand this results? levels(as.factor(miset1$facts_convict)) [1] 1 1 2 3 4 5 6 Don't know how you got your data that way, but I wonder if you've done str() on your data after whatever procedure you used to get to this stage.
