‘iCalendar’ Parsing

Status

lines of R code: 296, lines of test code: 97

Project Status: Initial development is in progress, but there has not yet been a stable, usable release suitable for the public. AppVeyor build status Codecov

Development version

0.3.0 - 2020-09-08 / 09:00:18

Description

A simple wrapper around the ‘ical.js’ library executing ‘Javascript’ code via ‘V8’ (the ‘Javascript’ engine driving the ‘Chrome’ browser and ‘Node.js’ and accessible via the ‘V8’ R package). This package enables users to parse ‘iCalendar’ files (‘.ics’, ‘.ifb’, ‘.iCal’, ‘.iFBf’) into lists and ‘data.frames’ to ultimately do statistics on events, meetings, schedules, birthdays, and the like.
