setEdgeTargetArrowOpacityDirect: setEdgeTargetArrowOpacityDirect

In tmuetze/Bioconductor_RCy3_the_new_RCytoscape: Display and manipulate graphs in Cytoscape >= 3.3.0

Description

In the specified CytoscapeWindow, set the opacity of the target arrow of the specified edge or edges. Opacity is an integer between 0 (invisible) and 255 (fully rendered).

Usage

setEdgeTargetArrowOpacityDirect(obj, edge.names, new.values)

Arguments

obj	a CytoscapeWindowClass object.
edge.names	one or more cy2-style edge names, String objects.
new.values	one or more integer objects, between 0 and 255.

Value

None.
