### 10.5.2 R packages

There are several dedicated R packages for parsing dates and times:

• hms provides a simple class for storing durations or time-of-day values and displaying them in the hh:mm:ss format. The hms package (Müller, 2020) is part of the tidyverse (see https://hms.tidyverse.org).

• anytime is an anything to ‘POSIXct’ or ‘Date’ converter (without requiring a format string).

• parsedate makes the very general date parsing utility from the git version control software available in R.

### 10.5.3 Books

• The book Advanced R (Wickham, 2014a) contains several chapters on functional programming.
