R help - Feb 2010 - subset() for multiple values

This code works:

subset(NativeDominant.df,!ID=="37-R17")


This code does not:

Tree.df<-subset(NativeDominant.df,!ID==c("37-R17","37-R18","10-R1","37-R21","37-R24","R7A-R1","3-R1","37-R16"))



how do i get subset() to work on a range of values?

Use ' %in%':

Tree.df<-subset(NativeDominant.df,!ID %in%
c("37-R17","37-R18","10-R1","37-R21","37-R24","R7A-R1","3-R1","37-R16"))
