Calculate the mean of columns of the array in R
In this approach, the user needs to call the colmean() function with the name of the array with its dimensions as the parameter to get the mean of the columns of the given array in the R language.
Syntax:
colMeans(data, dims )
where,
- data is the input array
- dims stands for dimensions
Example:
in this example, we will create an array with 3 dimensions with 1 to 12 elements and calculate column means using the colmeans() function in the R programming language.
R
# Initializing a 3D arraydata= array(1:12, c(2, 3, 3))# colmeans for one dimensionprint(colMeans(data, dims = 1))# colmeans for two dimensionprint(colMeans(data, dims = 2)) |
Output:
[,1] [,2] [,3] [1,] 1.5 7.5 1.5 [2,] 3.5 9.5 3.5 [3,] 5.5 11.5 5.5 [1] 3.5 9.5 3.5
