[R] subset syntax

[Grum, Mikkel]

Can anyone tell me what's wrong with this command??

xx<-subset(x,LOCAL.NAME==c("Chifumbata","Chikota"),select=c(13,16,19,23,26,2
9,30,33:48))

Warning message: 
longer object length
        is not a multiple of shorter object length in: LOCAL.NAME ==
c("Chifumbata", "Chikota")

both of the following commands work fine
xx<-subset(x,LOCAL.NAME==c("Chikota"),select=c(13,16,19,23,26,29,30,33:48))
xx<-subset(x,LOCAL.NAME==c("Chifumbata"),select=c(13,16,19,23,26,29,30,33:48
))

but I want a file with both the Chifumbatas and the Chikotas and several
others.

Cheers,
Mikkel
