Plot method for 'MST' objects
Plots a 2D Minimum Spanning Tree (MST) by producing a scatter
plot with segments using the generic function plot.
## S3 method for class 'MST' plot(x, ..., V1 = 1, V2 = 2, col.pts = "black", col.segts = "black", lty = 3)

further graphical parameters. |
V1 |
the numeric position or the name of the column to be used as the x coordinates of the points in the plot. |
V2 |
the numeric position or the name of the column to be used as the y coordinates of the points in the plot. |
col.pts |
color of the points (vertices/nodes) in the plot. |
col.segts |
color of the segments (edges) in the plot. |
lty |
line type. An integer or name: |
