colorFacet: Miscellaneous ggplot2 and grid Helper Functions

Description

These functions are used on ggplot2 objects or as layers when building a ggplot2 object, and to facilitate use of gridExtra. colorFacet colors the thin rectangles used to separate panels created by facet_grid (and probably by facet_wrap). A better approach may be found at http://stackoverflow.com/questions/28652284. arrGrob is a front-end to gridExtra::arrangeGrob that allows for proper printing. See http://stackoverflow.com/questions/29062766/store-output-from-gridextragrid-arrange-into-an-object. The arrGrob print method calls grid::grid.draw.

Usage

colorFacet(g, col = adjustcolor("blue", alpha.f = 0.3))
arrGrob(…)
# S3 method for arrGrob
print(x, …)

Arguments

g

a ggplot2 object that used faceting

col

color for facet separator rectanges

…

passed to arrangeGrob

x

an object created by arrGrob

Examples

# NOT RUN {
s <- summaryP(age + sex ~ region + treatment)
colorFacet(ggplot(s))   # prints directly
# arrGrob is called by rms::ggplot.Predict and others
# }
