Randomness is an essential part of many statistical and machine learning tasks. In R, there are a number of functions that can be used to generate random numbers, but the
runif()function is the most commonly used.
Something mildly embarrassing for me is that it took me a while to figure out why they call the command
runif(). That’s because, at first, I didn’t pronounce it
r unif but rather
*unif() means “uniform distribution” and
r stands for “random number.” There are several other functions based on the uniform distribution and Steven looks at those as well in this post.
