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

[Bill Osburn <bosburn@sjrwmd.com>]

Two nice answers

1)

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.

2)

If all your data (x) are numeric, then try

 

y <- x[,!is.na(colSums(x))]

Both worked nicely

 

Thanks
