If I am in doubt, I first make and isolated printout of the logical selection vector df=data.frame(FwdDataVols=100+rnorm(10)*100) df$FwdDataVols>10 && df$FwdDataVols<100 # gives FALSE df$FwdDataVols>10 & df$FwdDataVols<100 # gives FALSE TRUE FALSE..... subset(df,df$FwdDataVols>10 & df$FwdDataVols<100) # Probably more usual, but maybe more difficult to understand df[df$FwdDataVols>10 & df$FwdDataVols<100,] Dieter ______________________________________________ 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.
