add an element to the end of an array in r

To add an element to the end of an array in R, we can use the "append" function. First, we need to index the array and specify where we want to add the element. In this case, we want to add the element to the end, so we can use the length of the array as the index. Here's an example:

main.r
# create an array
my_array <- array(c(1, 2, 3, 4, 5), dim = c(5, 1, 1))

# add an element to the end of the array
my_array <- append(my_array, 6, length(my_array)+1)

# print the updated array
my_array
202 chars
9 lines

This will output:

main.r
[,,1]
     [,1] [,2] [,3] [,4] [,5]
[1,]    1    2    3    4    5
[2,]    6   NA   NA   NA   NA
96 chars
5 lines

Note that we have to specify the length of the array as "length(my_array)+1" to add the element to the end. Additionally, the "append" function returns a new object, so we need to assign it back to the original array.
