Hi,
I am writing a function and need to pass a function expression as an
argument, for instance,
myfun <- function( express) {
x<- c(1,2,3)
y<-express
}
if I call the above function by myfun( x*2 ), I get 2 as the result,
instead of 2,4,6 , could someone help me to
fix this problem ?
Furthermore, is that possible to operate this expression on different
variables? for example, in myfun(), I
might want to get u*2, z*2, etc. without having to say x<-u, x<-z to match
the expression.
Thanks a lot for your help.
best
