[R] Multiple assignments in one statement

Yes and no. Your function doesn't work because c() is a function and R is
call-by-value, so c(x,y,z) is just a value, like 7.
You could use lists like this:
> l <- list(x=NULL,y=NULL,z=NULL)
> l[c("x","y","z")] <- 1:3
That, together with attaching lists (help(attach)), might give you the
effect you want.

Subject: [R] Multiple assignments in one statement
Is this possible?
For instance, I have a function that returns a vector length 3. In one
statement I'd like to assign each element of the vector to different
variables. Syntactically, I hoped this would work:
c(x,y,z) <- myfun();
