R: apply a function to every element of two variables respectively

Question

I have a function with two variables x and y:

fun1 <- function(x,y) {
  z <- x+y
  return(z)
}

The function work fine by itself:

Answer 1

Well you're using vectors of different length but maybe this will help if I understand correctly. I just made a dumby function with variable i

fun1 <- function(x,y) {
  z <- x+y
  return(z)
}


fun1(15,20)


Lx  <- c(1:56)
Ly <- c(1:121)


fun1I <- function(x,y,i)
{


  fun1(x[i],y[i])


}


fun1IR <- function(x,y)
{


  function(i)fun1I(x=x,y=y,i=i) #return dumby function

}



testfun <- fun1IR(Lx,Ly) # creates function with data Lx and Ly in variable i

mapply(testfun, 1:min(length(Lx),length(Ly)))
