Julia-R Cheatsheet – Creating Matrices

Creating Matrices

How to create matrices in Julia and R? The following table translates the most common Julia commands into R language.

Julia R
Create a matrix
 
A = [1 2; 3 4]
 
A = matrix(c(1,2,3,4),2,2)
Create a 2 x 2 matrix of zeros
 
A = zeros(2,2)
 
A = matrix(0,2,2)
Create a 2 x 2 matrix of ones
 
A = ones(2,2)
 
A = matrix(1,2,2)
Create a 2 x 2 identity matrix
 
A = eye(2,2)
 
A = diag(2)
Create a diagonal matrix
 
A = diagm([1;2;3;])
 
A = diag(c(1,2,3))
