plot: Plot gene regulatory network
In GeneReg: Construct time delay gene regulatory network

Plot gene regulatory network based on a series of time delay linear models.

1	plot(edge, ...)

`edge`	output of timedelay.lm.batch, which has 4 columns. The first column is the regulator, the second column is the target gene, the third column is the regression coefficient, the fourth column is time delay.
`...`	Additional arguments, passed to plot.igraph.
