Hello Bill,

 

Another way would be:

 

apply(YOURDATAFRAME,2,anyMissing)

 

this will give you which column contains missing values or not.

 

Bests,

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
