colorFacet {Hmisc}

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 https://stackoverflow.com/questions/28652284/. arrGrob is a front-end to gridExtra::arrangeGrob that allows for proper printing. See https://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 class 'arrGrob'
print(x, ...)

Arguments

g

a ggplot2 object that used faceting

col

color for facet separator rectanges

...

passed to arrangeGrob

x
