graphicsList: Convert a list of "trellis" objects or list of "ggplot" objects into a "graphicslist" object.

Description

Convert a list of "trellis" objects or list of "ggplot" objects into a "graphicslist" object.

Usage

graphicsList(...)

Arguments

…

The list can either be a "list" object, such as list(g1, g2, g3), or the actual list g1, g2, g3. All the g* objects must be the same class, either "trellis" or "ggplot". The "list" object may be an array with dim or dimnames, with length(dim(object)) either 1 or 2. An actual list, or a "list" object with one dimension, will be coerced to a column vector of graphics objects.

Value

A "graphicsList" object which can be sent to microplot.graphicsList. See microplot.graphicsList for more discussion.
