phinterval provides a <phinterval> (say “potentially-holey-interval”)
class for working with time intervals that potentially contain gaps such
as:
-
An individual’s employment or educational history.
-
A meeting schedule for the work day.
-
All of the Monday’s in a month.
Sometimes it is useful to consider these holey time-spans as a single observation rather than a collection of observations. phinterval provides tools to work with such observations.
The implementation of, and conventions used by, this package borrow
heavily from the lubridate
<interval> class. The <phinterval> class is meant to be a
super-class of <interval>, meaning that the two classes are often
interchangeable.
You can install the development version of phinterval from GitHub with:
# install.packages("devtools")
