It's hard to solve without a *reproducible* example. Is your data set really called 'BMI'? (i.e. should you be saying BMI$BMI, or just BMI (if your data frame is attached), or mydata$BMI? If your data set *is* called BMI, does it make a difference if you rename it to e.g. BMIdat? What are the results of ls() ? ______________________________________________ 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.
