Hi All,
My R code takes very long time to finish the processing. I want to see at what stage the script is running. So I wrote some output messages using cat. But instead of displaying the cat messages at different stages they are buffered and displayed in the end when entire processing is done. Can you please suggest how to stop this buffering or some alternative way to display messages

Thank you
