String manipulation functions in R ( part 2)

First part of this series of posts.


This is the second part of a series of posts that treat the subject of strings and text manipulation in R. Every time some functions are picked with basic examples and shared here. I hope that at the end of this series, I'll have a good archive of lessons from beginners level to expert level.

The points we will see in this part 2 are:

1. character encoding 
2. length of a string 
3. lowercase and uppercase conversion 
4. basic string comparison 
5. concatenating strings
6. extracting sub-strings
