plotGML: Plot Network in GML
In XMRF: Markov Random Fields for High-Throughput Genetics Data

Plot the network in graph modeling language (GML).

1	plotGML(x, fn = "", th = 1e-06, i = NULL, weight = FALSE, vars = NULL)

`x`	a `GMS` object.
`fn`	file name to save the GML file.
`th`	numeric value, default to 1e-06. To specify the threshold if the estimated coefficient between two variables is to be considered connected.
`i`	index of the network (along the regularization path) to be plotted. Default to `NULL` for optimal network.
`weight`	boolean value to indicate if writing the stability on the inferred edges, default to `FALSE`.
`vars`	vector of variable names, default to `NULL`.
