replacing all NA's in a dataframe with zeros...
I've seen how to replace the NA's in a single column with a data frame
*> mydata$ncigs[is.na(mydata$ncigs)]<-0
*But this is just one column... I have thousands of columns (!) that I need
to do this, and I can't figure out a way, outside of the dreaded loop, do
replace all NA's in an entire data frame (all vars) without naming each var
separately. Yikes.
I'm racking...
