iplot.manip {iplots}

R Documentation

iPlot manipulation functions

Description

The following functions are used to mainpulate iplots. They are NOT part of the official API and may disappear without warning. Most of them are legacy functions introduced before iplot.opt was available.

iplot.backend retrieves or sets the iPlots back-end.

iplot.resetZoom reset zoom

iplot.rotate set plot rotation

iplot.setExtendedQuery set text for extended query

iplot.zoomIn zoom into specified area

iplot.zoomOut zoom out (the coordinates are ignored as the zoom is heararchical)

iplot.location get or set the location of the iplot

iplot.size get or set the size of an iplot plot

Usage

iplot.backend(type = NULL)
iplot.resetZoom() 
iplot.rotate(i) 
iplot.setExtendedQuery(str, plotID=.iplot.curid) 
iplot.zoomIn(x1, y1, x2, y2) 
iplot.zoomOut(x, y)
iplot.location(x, y, relative=FALSE, plot=iplot.cur())
iplot.size(width, height, plot=iplot.cur())
## S3 method for class 'iobj'
print(x, ...) 
## S3 method for class 'iplot'
print(x, ...) 

Arguments

i	rotation orientation
plotID	plot ID (number)
str	string to show on extended query or FALSE or NULL to disable extended query
type	back-end type - one of "awt", "swing" or "opengl" (or any unambiguous first part hereof) to set the type or NULL to retrieve the current back-end type
x1	basis coordinate for the x axis
y1	basis coordinate for the y axis
x2	edge coordinate for the x axis
y2	edge coordinate for the y axis
x	object to print or x-coordinate
y	y-coordinate
plot	plot to query or move (id or object)
relative	can be TRUE, FALSE or another plot
width	width of the plot (in pixels)
height	height of the plot (in pixels)
...	additional parameters

Details

iplot.location, iplot.size: those functions either query or set the location or size of the plot. If either of the coordinates is missing, the size/location in that coordinate will not be changed. If both coordinates are missing, the functions have no side effect and just return the current size (iplot.size) or location and size (iplot.location) as named vectors (x, y for location and width, height for size).

iplot.backend determines the back-end used by iplots. The choices are awt, swing an dopengl. Not all back-ends are available on all platforms. AWT is the most compatible back-end and available on all platforms, Swing has more modern look and feel and OpenGL sacrifices text rendering quality for speed (i.e. OpenGL backend is best for large data). When no backend is specified, the function has no side effect and just returns the currently requested back-end. Currently there is no indication whether the back-end request was honored or not. If a backend is not supported, the request is silently ignored.
