To change all elements of an array in R, you can use the [] or replace() function.
Using the [] function:
# create an array
my_arr <- array(data = c(1,2,3,4,5), dim = c(5,1,1))
# change all elements to 0
my_arr[] <- 0
print(my_arr)
Output:
, , 1
[,1]
[1,] 0
[2,] 0
[3,] 0
[4,] 0
[5,] 0
Using the replace() function:
# create an array
my_arr <- array(data = c(1,2,3,4,5), dim = c(5,1,1))
# change all elements to 0
my_arr <- replace(my_arr, TRUE, 0)
print(my_arr)
Output:
, , 1
[,1]
[1,] 0
[2,] 0
[3,] 0
[4,] 0
[5,] 0
In both examples, we created an array my_arr with 5 elements. We then changed all elements to 0 using either the [] or replace() function. The resulting array had all elements set to 0.
