return value in function
2 messages · li xian, Jason Turner
suppose I have a function example:
getMatrix <- function(a,b){
A1<-diag(1,2,2)
}
If I want to get the both the A1 and dim(A1) from the function, Can I do
return(A1,dim(A1)) inside the function ? And how can I access A1 and
dim(A1) later on?
The general approach for this is to use a list
getMatrix <- function(a,b){
A1<-diag(1,2,2)
list(diag=A1,dim=dim(A1))
}
foo <- getMatrix(something)
foo$diag
foo$dim
Cheers
Jason
