plot-otgrid: Plots for two-dimensional Optimal Transport

In gridOT: Approximate Optimal Transport Between Two-Dimensional Grids

Plots for two-dimensional Optimal Transport

Description

Plot two-dimensional grids or visualize the pivot measure.

Usage

## S3 method for class 'otgrid'
plot(x, num.col = 256, useRaster = TRUE, ...)

## S3 method for class 'otgridtransport'
plot(x, num.col = 256, useRaster = TRUE, back.col = "lightblue", ...)

Arguments

x	an object of class "otgrid" or "otgridtransport"
num.col	number of colors (grey) to use.
useRaster	parameter passed to the image function.
...	further arguments (currently unused).
back.col	color of the background.

Details

For objects of class "otgrid", the grid is plotted as a greyscale image.

For objects of class "otgridtransport", the pivot measure is visualized as follows: the two grids of the transport are plotted in the left upper (from) and right lower (to) corner. The pivot measure is in the left lower corner such that the marginals match.

Value

No return value, called for side effects.
