write.plot {BoutrosLab.plotting.general}R Documentation

Simplifies plotting by standardizing and centralizing all output-handling

Description

Handle various graphics-driver weirdness and writes an output file and returns 1 or returns the trellis.object

Usage

write.plot(
	trellis.object,
	filename = NULL,
	additional.trellis.objects = NULL,
	additional.trellis.locations = NULL,
	height = 6,
	width = 6,
	size.units = 'in',
	resolution = 1000,
	enable.warnings = FALSE,
	description = "Created with BoutrosLab.plotting.general"
	);

Arguments

trellis.object

A trellis object to be plotted

filename

Filename for output, or if NULL (default value) returns the trellis object itself. Will automatically grab the extension used.

additional.trellis.objects

List of additional trellis objects to add to main plot. Default to NULL

additional.trellis.locations

List of coordinates for additional trellis objects. Must be represented using variable names 'xleft', 'ybottom', 'xright' and 'ytop'. Defaults to NULL

height

Figure height, defaults to 6 inches

width

Figure width, defaults to 6 inches

size.units

Figure units, defaults to 'in'

resolution

Figure resolution, defaults to 1000

enable.warnings

Print warnings if set to TRUE, defaults to FALSE

description

Short description of image; default NULL

Value

Returns the trellis.object if filename is NULL or writes the plot to file if a filename is specified.
