Bill, I addressed the first issue with the data frames and length(x). But my loops still isn't working. More importantly, you commented that I should be using if(...) ... else ... rather than ifelse(.,.,).
Please help me understand the difference. I thought ifelse was just a faster way of doing if(...)...else(.,.,). What is the difference between these two methods ? -- View this message in context: http://r.789695.n4.nabble.com/What-am-I-doing-wrong-with-this-loop-tp3332703p3334591.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.
