I wanted to test if there exists already a name (which is incidentally a substring of another name) in a dataframe. I did e.g.:
> data(swiss) > names(swiss) [1] "Fertility" "Agriculture" "Examination" "Education" [5] "Catholic" "Infant.Mortality" > ! is.null(swiss$EduX) [1] FALSE > ! is.null(swiss$Edu) [1] TRUE I did not expect to get TRUE here because ``Edu'' does not exist as name of ``swiss''. I did finally: > 'Edu' %in% names(swiss) for which I got the expected FALSE. My question: What is the recommended way to do such a test?
