Graphical-parameters: Change and Retrieve Graphical Parameters
In MangoTheCat/RNMGraphics: NONMEM graphics

Description Usage Arguments Details Value Note Author(s) Examples

setGraphParams may be used to change graphical settings in a manner similar to the lattice package's function trellis.par.set, while getGraphParams is similar to trellis.par.get. Settings apply globally and to all plots generated by this package, and don't just apply to devices.

setAllGraphParams(settings)

getAllGraphParams()

setGraphParams(field, setting)

getGraphParams(field)

`settings`	A full list of graphical parameters. See the documentation for RNMGraphics.
`field`	A string with the name of the field/option (e.g. loess.line) that the user wishes to change or retrieve

At the moment, the following fields exist:

plot.symbol - The plot points which appear in scatter plots.

superpose.symbol - The plot points which appear in scatter plots whenever a grouping variable is used.

plot.line - The plot lines which appear in scatter plots, whenever lines are chosen to connect data rather than points.

plot.text - The plot labels that appear in scatter plots when type "i" is used.

loess.line - The loess smoother curve which can be added to scatter plots.

histogram - The fill colour and outline colour of histogram rectangles.

refline - The reference lines that can be added to many plots.

barchart - The fill colours of polygons used in nmBarchart.

axis.text - The text that appears in y- and x-axis labels.

box.rectangle - The rectangles in box plots.

title.text - The plot main title text.

grid - The reference/background grid text.

strip.bg - Strip background settings

layout.heights - Equivalent to the lattice setting of the same name

layout.widths - Equivalent to the lattice setting of the same name

strip - Strip function to use

panelLayout - Currently unused

panelMisc - Miscellaneous controls over lattice panels

legend - Settings for the legend.

setGraphParams returns nothing. getGraphParams returns a list with the configuration for the particular field/option chose, and getAllGraphParams returns a list (of lists) with all current configuration information.

Some of these settings and their implementations will almost certainly change in forthcoming releases.
