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? -- David Winsemius Alameda, CA, USA ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
