saveImage: saveImage

In RCytoscape: Display and manipulate graphs in Cytoscape

Description

Write an image of the specified type to the specified file, at the specified scaling factor. Note: the file is written to the file system of the computer upon which Cytoscape is running, not R – in those cases where they are different.

Usage

saveImage(obj, file.name, image.type, scale)

Arguments

obj	a CytoscapeWindowClass object.
file.name	a char object. Use an explicit, full path, or this file will be written into your home directory.
image.type	a char object. 'jpg' is the only image type currently supported
scale	a numeric object. How large (or small) to scale the image.

Value

None.
