I have a data.frame "e" and would like to extract the 23rd column,
remove any NA's and then remove any values >= 30. I can do it in steps
such as this but have failed to figure out how to do it in a single line
.... any suggestions?
first <- e[,23]
second <- first[!is.na(first)]
third <- second[second<=30]
thanks a bunch
