Can you assign two variables simultaneously in R?

Question

I am using the example of calculating the length of the arc around a circle and the area under the arc around a circle based on the radius of the circle (r) and the angle of the

Answer 1

As Gregor said, there's no way to do it exactly as you said and his method is a good one, but you could also have a vector represent your two values like so:

# Function that adds one value and returns a vector of all the arguments.
plusOne <- function(vec) {

  vec <- vec + 1
  return(vec)

}

# Creating variables and applying the function.
x <- 1
y <- 2
z <- 3
vec <- c(x, y, z)
vec <- plusOne(vec)

So essentially you could make a vector and have your function return vectors, which is essentially filling 3 values at once. Again, not what you want exactly, just a suggestion.
