The help page for mean still says there is a method for data.frame although
this has been deprecated for several versions and in R 3.0.0 beta I get:
mean(data.frame(x=rnorm(10), y=rnorm(10)) )
[1] NA
Warning message:
In mean.default(data.frame(x = rnorm(10), y = rnorm(10))) :
argument is not numeric or logical: returning NA
I read in news():
o mean() for data frames and sd() for data frames and matrices are
defunct.
Shouldn't the help page be amended?
Has been amended this morning by Martin Maechler, although I do not see
a reply.
Best,
