In JosephCrispell/plotteR: A collection of functions to help with base R plotting

This function should be ran within a for loop, it produces a progress bar to indicate how many iterations have passed

1	progress(i, n)

`i`	A numeric value indicating the current iteration of the containing for loop
`n`	A numeric value indicating the total number of iterations of the containing for loop

# Set the number of iterations of the for loop
n <- 1000

for(i in 1:n){
 
  # Sleep for a tenth of a second
  Sys.sleep(0.01)
  
  # Update the progress bar
  progress(i, n)
}
