Description Arguments Examples

Description

Plot an instance of the fvcom.grid class and overlay the trajectories given by xy.

Arguments

x

A fvcom.grid instance

xy

A list with matrices x and y components that contain the trajectories to plot. The columns of xy$x are plotted against the columns of xy$y, so each particle trajectory should be in a column and each time index in a row.

plot.units

The units for plotting. Either 'm' for meters or 'll' for latitude and longitude.

xy.units

The units of xy. Either 'm' for meters or 'll' for latitude and longitude.
