You _need_ to learn how regular expressions work. There are many dozens of ways 
to learn this topic... web tutorials, YouTube videos, reading the ?regex help 
page in R. Start at the beginning, and look for special characters like ".", 
"$", and "\." (which has to be "\\." in R). It shouldn't take long to pick up 
enough skill to solve this yourself, and you will be a more complete data 
analyst for it.
