Create a function in R with multi outputs like matlab

Question

I'm not familiar with R, just a newbie. So I want to translate some code from matlab to R. But I have the problem about the output of function. I want to create a function give output to two specify variable, like this:

list[a,b]<-function(var1,var2){
a<-var1 + var2
b<-var1 - var2
return list(a,b)
}

But my code is not working, please help me to solve this problem.

Answer 1

You seem to have some fundamental misunderstanding about functions in R. Read "An Introduction to R". Also, return is a function in R.

myfun <- function(var1, var2){
  a <- var1 + var2
  b <- var1 - var2
  return(list(a, b))
}

myfun(1:5, 10:6)
#[[1]]
#[1] 11 11 11 11 11
#
#[[2]]
#[1] -9 -7 -5 -3 -1
