ggopt: Set global options for ggplot.

In hadley/ggplot1: Before there was ggplot2

Set global options for ggplot.

Description

These are aliased into every plot object, so that p$grid.col will return the default grid colour, unless it has been overriden for a particular plot object. You can change the global options using the function, or the options for a specific plot by setting the values directly on the object. See the examples for more details.

Usage

theme_bw

theme_default

ggopt(...)

ggtheme(theme)

Arguments

...	named options to set
theme	list of options set

An object of class list of length 11.
