Create Empty Matrix in R (Example)

 

In this R programming article you’ll learn how to create an empty matrix with zero rows.

The content of the article looks as follows:

You’re here for the answer, so let’s get straight to the R syntax…

 

Example: Creating Matrix with Zero Rows

The following syntax explains how to create an empty matrix in the R programming language by using the matrix() function and the ncol and nrow arguments.

my_mat <- matrix(ncol = 3, nrow = 0)             # Applying matrix() function
my_mat                                           # Printing matrix to console
# [,1] [,2] [,3]

Have a look at the previous RStudio console output: It shows our matrix with zero rows.

We can also modify the column names of our matrix using the colnames function:

colnames(my_mat) <- c("Col1", "Col2", "Col3")    # Rename columns of matrix
my_mat                                           # Printing matrix to console
# Col1 Col2 Col3

Looks good!
