Stat 412 9: Strings and Regular expressions with stringr 

Thank you, Thank you, Thank you... I really needed this lesson in REG Ex...

Regex or regular expressions are a compact way to edit and manipulate strings of text. Regex is a language for describing and finding patterns within a string or text. It is not a programming language in itself.

Really usetal and detailed tutorial. Thanks a lot

Hi Kelsey, your videos are very helpful. But i have notice a thing which is entire playlist is shuffled with missing videos. Can you please arrange in sequence with all videos.

This was helpful. Thanks.

writeLines() is another way of print but vector (horizontal) style

This is a very overview of stringr and regex. However, I find it difficult to read your code even at the highest resolution. The contrast is quite poor. Consider a) increasing your font and size b) using a dark background.

can i get the cheatsheets?
