Dear R development Team: I really know very little, so you may ignore this post. I have found that my students often make the mistake of mixing up comparisons and assignments with negative numbers:
if (x<-3) do_something; I parenthesize, but every once in a while, I forget and commit this mistake, too. so, I would suggest that R simply warn about an ambiguity. that is, it could suggest a space either between the < and - , or after the <- . x< -3 ## means comparison already x<- 3 ## means assignment already but warn when x<-3 ## ambiguity warning instead of assignment x<-(whatever) ## ok just a suggestion... regards, /iaw ---- Ivo Welch (ivo.we...@brown.edu, ivo.we...@gmail.com) ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
