gplot: make a plot for directional graph from edge matrix graph form

In loop: loop decomposition of weighted directed graphs for life cycle analysis, providing flexbile network plotting methods, and analyzing food chain properties in ecology

Description

can change the link line style and color, can add arrows at the ending points, this function requires an edge matrix form of graphs, compared to another similar function 'gplot1'.

Usage

gplot(edgemat,arrow=TRUE,lty=1,col=8,weighted=TRUE)

Arguments

edgemat	graph edge matrix form, without confusion, 'loop' package will have two types for the graph storage: square matrix from (argument is 'gemat') and edge matrix form (argument is 'edgemat').
arrow	default is TRUE, denoting arrows should be added in the plot
lty	line style for each graph link
col	line color for each graph link
weighted	if TRUE, the links/edges will be weighted based on the value present in the 3rd column of edgemat, different edges then will have different line widths for representing them. Otherwise, all edges have the same line width. Default is TRUE
