[R] weighted.mean and na.rm=T in R-1.6.2

Hi It looks like the na.rm flag is not working in function weighted.mean. weighted.mean(mat95$U,mat95$fpanual) [1] NA weighted.mean(mat95$U,mat95$fpanual,na.rm=TRUE) [1] NA mat95 - mat95[!is.na(mat95$fpanual),] weighted.mean(mat95$U,mat95$fpanual) [1] 14.93259 Regards EJ
