title: R: Generating random points with different mean and sd for each attribute
body: <p>Is there any way in R, other than with loops, to create a matrix using different means and standard deviations for the matrix's columns?</p>
  
  <p>For example, I want to create a 3x4 matrix representing 3 points with 4 attributes each, such that every column (every attribute) has its own mean and sd.</p>
