Hi,
I'm trying to replace the NA in my database by using the option fill=NA but for some reason it doesn't work. What is strange for me is that there is not an error message, just nothing is happening after i click on run.
Here is my the full function that I use:
C <-spread(B, AGEACT, type, fill=NA, convert = FALSE, drop = TRUE, sep = NULL)
Thanks in advance.
