Homework question? This one's pretty easy; see
?regex
?gsub
A couple of examples on gsub()'s help page are rather close to what
you need. The basic structure is
gsub(<string to replace>, <replacement string>, name_of_string)
where the strings are enclosed in quotes. If you need to apply this
function to each row of your data frame, see ?apply and put the gsub()
code into an anonymous function.
Best of luck!
