Hi everyone,  

I have a function containing a loop that takes some time to complete. Before I enter the loop I want to print a text string to the screen explaining what is being calculated, however, I find that the information is not printed until the function exits. Is there a way of immediately printing a message from within a function as a side effect before it returns?

code example:

myFunc <- function(){
  print.noquote("some message that I want to print before exiting the function")
  j <- 0
  for (i in 1:1000000){
    j <- j + 1
  }
  j
}  

Best wishes,
David
