Thanks to the R creators for such a great statistical system. Thanks to the R help list, I have (finally) gotten far enough in R to have a question I hope to be worth posting.
I'm using the recode function from John Fox's car package and have encountered some unexpected behavior. Consider the following example: ## Begin cut-and-paste example require( car ) set.seed(12345) nn <- sample( c( 2, 4 ), size=50, replace=TRUE ) rr <- recode( nn, "2='TWO';4='FOUR'" ) table( rr, exclude=NULL ) ss <- recode( nn, "2='Num2';4='Num4'" ) # Doesn't work as expected table( ss, exclude=NULL ) tt <- recode( nn, "2='TWO'; 4='Num4'" ) table( tt, exclude=NULL ) uu <- recode( nn, "2='Num2'; 4='FOUR'" ) table( uu, exclude=NULL ) ## End cut-and-paste example All but the recoding to ss work as expected: I get a character vector with 23 instances of either "FOUR" or "Num4" and 27 instances of "TWO" or "Num2". But for the ss line, wherein all the strings to be assigned contain a digit, the resulting vector contains all NAs. Using str(), I note that ss is a numeric vector. Is there a tidy way (using recode) to recode numeric values into character strings, all of which contain a digit? I have a workaround for my current project, but it would be nice to be able to use mixed alphanumeric strings in this context. Thanks in advance for any insight you can give into this question.
