Multidimensional Array in R Last Updated 22 Apr 2020 Arrays are the R data objects which can store data in more than two dimensions For example If we create an array of dimensions (2 3 4) then it creates 4 rectangular matrices each with 2 rows and 3 columns These types of arrays are called Multidimensional Arrays.

GeeksforGeeks using the dim() Create 3D array function in R
m = array(160 dim=c(345)) m[215] [1] 50 m[215] = 50 m[215] [1] 50 Type m to see the whole 3d array ) In your example you'd set up your initial array as m = array(NA dim=c(36564)) (this will fill it with NAs to start with do you have data to fill it up.
