Is there a way in R (12.x) to avoid the implicit coercion of factors to integers in the context of subscripts?
If this is not possible, is there a way to get at least a warning, if any coercion of this type happens, given that the action of this coercion is almost never what is wanted? Of course, in the rare case that as.integer() is applied explicitly onto a factor, the warning is not needed, but certainly not as disastrous as in the other case. Probably, in a future version of R, an option similar to that for partial matches of subscripts might be useful to change the default from maximal unsafety to safe use. ______________________________________________ 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.
