All,
S-Plus 2000 on Windows 2000
I am trying to create some binary data from columns in a data frame.
When I issue the command
> TTS.Predictors.Cats <- ifelse(Cool.TTS$Deck1.Hgt > 0 &
Cool.TTS$Deck1.Hgt < 3048, 1, 0)
I think I am going to get 1's when the value is within the range and 0's
when it is not. Instead, I get all NA's. If I use one condition or the
other, it works properly, but I need to have 1's when both conditions
are true, not just one. What am I doing wrong? Thanks for the help.
Win
