[R] 2 simple doubts

[Frederico Zanqueta Poleto]

Hello,

I'm just start learning R/S-Plus, so I think this 2 doubts is going to 
be too easy for you...

1) I couldn't discover what is the command for a concatenation of 2 
variable strings.

2) For example, if I have three variable strings, and each one has the 
name of a variable in a data matrix:
a<-V1
b<-V2
c<-V3
, is it possible to construct a command like this:
tree(a~b+c,data=DS1)
, that would do the job of tree(V1~V2+V3,data=DS1) ?
I know that how I've written here doesn't work, but I hope I've 
explained well what I'd like to do.

Thanks.

Sincerely,
