Plots a graphical representation of the flow field together with the polygon structure. This is a method for the generic function plot and can therefore be called as plot(arena_object).

# S3 method for arena
plot(x, arrow_scale = 1, grid = FALSE, ...)

Arguments

x

An object of class arena, see details.

arrow_scale

The length of the longest arrow is arrow\_scale times the distance between two neighbouring grid points.

grid

If TRUE, a grid is drawn marking the boxes around the grid points.

...

Further arguments to the plot funtion.

Details

An arena object describes the arena in which the function is to be used. It is a list containing elements lat, lon, U, V and S (in that order), where lat and lon are vectors storing the latitude and longitude values of the grid points used, U and V are matrices with the corresponding flow velocities in west-east and south-north direction, and S is a matrix in which each grid points has an integer number, either giving the polygon it belongs to (if > 0) or stating that this grid point lies on land (if == 0).
