I have a dataframe that has many addresses but they are all in uppercase and I want them to be in lower case but keeping the first letter of the word as an upper case.

I use the function lowercase but the whole word turns lower case

in this case 

tolower("231 MATTIE'S WAY")
[1] "231 mattie's way"

but I need it like 

"231 Matties's Way"

Any help on how I could do that?

  • The examples in the documentation for `tolower` contain a simple title case function. There is also such a function in the **stringr** package, I believe. – joran Feb 25 '19 at 21:30
  • Thanks for pointing those questions out, I got the answer from there:) – Juan Lozano Feb 25 '19 at 21:34
