R Documentation
Plot an instance of the fvcom.grid class and overlay the
trajectories given by xy.
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.
...
Additional arguments to be passed to
matlines.
Examples
{
# Create a set of random trajectories.
nodes = get.nodes(ocean.demo.grid)
set.seed(1)
x = apply(matrix(rnorm(1000, 0, 0.01), 250), 2, cumsum) - 69.5
y = apply(matrix(rnorm(1000, 0, 0.01), 250), 2, cumsum) + 42.5
lines(ocean.demo.grid, list(x=x, y=y), lty=1)
