Re: S-PLUS: na.omit on data.frame columns

Bill,
  How about

as.data.frame(lapply(DF, function(x)
if(any(is.na(x))) NULL else x))

where DF is the name of your data.frame.

Subject	[S] S-PLUS: na.omit on data.frame columns

I have a data.frame and want to remove
all columns where there is an NA. So far I can only get na.omit to work
on rows.
 
After googling for several hours I still
can’t locate any ideas. Has anyone done na.omit or something, on columns?
 
With my current data.frame I should go
from 16x78 to 16x28
