Strings and dates in R

In this two part workshop we will discuss working with strings and dates in R. First, we will review convenience functions for working with dates using the lubridate package.  Topics will include importing, formatting, and performing arithmetic with dates.  In the second part, I will offer an introduction to the stringr package which makes the popular stringi library available to R.  In both parts, the emphasis will be on practical examples rather than an exhaustive catalog of everything these packages can do.
