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

[Sebastien Bihorel <Sebastien.Bihorel@cognigencorp.com>]

Hi,

If mydf is your dataframe, this should do the trick: mydf <- mydf[,which(apply(mydf,2, function(x) is.element(NA,x))==F)]

Be aware though that this will transform your data frame into a vector if only one column has no NA values.

Hope it helps

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
