last.plot.get.info {AdhereR}R Documentation

Access last adherence plot info.

Description

Returns the full info the last adherence plot, to be used to modify and/or to add new elements to this plot.

Usage

last.plot.get.info()

Details

This is intended for advanced users only. It may return NULL if no plotting was generated yet, but if one was, a list contaning one named element for each type of plot produced (currently only baseR and SVG are used). For all types of plots there are a set of mapping functions useful for transforming events in plotting coordinates: .map.event.x(x) takes a number of days x, .map.event.date(d, adjust.for.earliest.date=TRUE) takes a Date d (and implictely adjusts for the earilerst date plotted), and .map.event.y(y) takes a row ("event" number) y. Besides the shared elements (see the returned value), there are specific ones as well. For baseR, the members old.par and used.par contain the original (pre-plot) par() environment and the one used within plot(), respectively, in case these need restoring.

Value

A list (possibly empty) contaning one named element for each type of plot produced (currently only baseR and SVG). Each may contain shared and specific fields concerning:
