Dear R Helpers, I am trying to write a character value to the row of a data frame and am running into a problem that I don't have when I do this for numeric arguments. For example, the following works just fine:
> test<-data.frame(number=numeric(1)) > test[1,]<-.5 > test number 1 0.5 But the following bombs out: > hold<-data.frame(symbol=character(1)) > hold[1,]<-"NYSE:MMM" Warning message: In `[<-.factor`(`*tmp*`, iseq, value = "NYSE:MMM") : invalid factor level, NAs generated Could someone please guide me as to what adjustment I need to make to assign this character value to this row of the data frame? Your help would be very much appreciated. --John Sparks ______________________________________________ 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.
