Dear R-Friends,
i encountered the following problem:
i wanted to apply(x,2,mean), where x is an array (3720 x 90), every single
column has a certain number of NAs, so the output of apply is a vector of
NAs.
Is there a possibility (other than reducing every single column with
na.omit()) to deal with this.
Thanks,
Thomas

NAs

I suspect that apply(x,2,mean,rm.na=TRUE) will do what you want.
("na.rm" is an optional argument to mean -- see ?mean. sd() has a similar
option.)
