Dear useRs,
I have just noticed that when input is only NA with na.rm=TRUE, mean()
results in NaN, whereas median() and sd() produce NA. Shouldn't it all
be the same? I think NA makes more sense than NaN in that case.
x <- c(NA, NA, NA) mean(x, na.rm=TRUE) [1] NaN median(x, na.rm=TRUE) [1]
NAsd(x, na.rm=TRUE) [1] NA
Thanks for any feedback.
Best,
Ivan
