OutDec affects output, only.
I was doing something like > options(OutDec = ",") > df <- data.frame(var = rep(1:8/4, 10), x = rnorm(80)) > df.a <- aggregate(df$x, by = list(var = df$var), FUN = sum) > as.numeric(df.a$var) [1] NA NA NA 1 NA NA NA 2 Warning message: NAs introduced by coercion in: as.double.default(df.a$var) because I needed df.a$var as numeric again. > > 2) anova yields the same warning as summary > > It does not in current R: try any fairly recent version of R-devel. > > Please don't keep reporting a problem we have already fixed, > as the FAQ and the posting guide explicitly ask of you. Sorry about that. I wasn't aware that the error was in a fixed subroutine that is used by summary and anova. I'm hestating to use a R-devel version because I haven't tried installing R from a tar.gz (I'm one of those lazy windows users that prefer the .exe version). For now I think I'll return to the good old option(OutDec = "."). > > [...] > > > -- > Brian D.
