First of all, let me apologize, as this is probably an absurdly basic question. I did search before asking, but perhaps my ineptitude didn't allow me to apply what I read to what I'm doing. Totally new to R, and haven't done any code in any language in a long time.
Basically I've got categories. They're department codes for doctors (say, 9999 for radiology or 5555 for endocrinology), which of course means that there are a good number of them, i.e. it's not practical for me to write them all out as I usually see in examples of categorical variables (factors). And then I've got a list of doctors that I'm actually interested in. I have the department codes associated with each, but I need to map the department name to the doctor name. So I might have Greg Jones, Bob Smith, Tom Wilson, etc... to go with 1234, 9999, 2222, etc. I need to turn Greg Jones, Bob Smith, ... and 1234, 9999, ... into Greg Jones, Bob Smith, ... Cardiology, Radiology, .... Obviously I could just search and replace within the csv files but I need something durable that I can run things through repeatedly. Anyhow, thanks to anyone willing to humor me with an answer. -- View this message in context: http://r.789695.n4.nabble.com/Factors-I-think-tp3800413p3800413.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
