Writing Programs for Specific Requirements

Hey. I an having an issue understanding this particular code asked in relation to the specific question below. Specifically the use of "(1)" next to the x. any help in regards to the same would be appriciated.

Q. Write a function called error_avg that takes a value k and returns the average of the vector x after the first entry changed to k. Show the results for k=10000 and k=-10000.


x <- Galton$child

error_avg <- function(k){

x[1] <- k





In R we index into a vector by position with square brackets.
