This is work in progress. The aim is to move openair from lattice to ggplot2 graphics. When openair started, ggplot2 did not exist and in the early days of ggplot2 it was slow and lacking many features. These issues have changed. There are several reasons for doing this:

• It will be easier to maintain openair based on ggplot2 rather than lattice
• ggplot2 is actively being developed and there is a growing list of other packages that build on ggplot2
• It will be easier for users to modify plots 'after the fact'

The plotting functions that currently (mostly) work include timeVariation, polarPlot, TheilSen.

Installation of openair from GitHub is easy using the devtools package. Note, because openair contains C++ code a compiler is also needed. For Windows - for example, Rtools is needed.

require(devtools)
install_github('davidcarslaw/ggopenair')

This repository will gradually implement most (but not all) openair functions in ggplot2. The package should be considered experimental and unstable until it replaces openair.
