torusAxis {sdetorus}

Draws pretty axis labels for circular variables

Description

Wrapper for drawing pretty axis labels for circular variables. To be invoked after plot with axes = FALSE has been called.

Usage

torusAxis(sides = 1:2, twoPi = FALSE, ...)

Arguments

sides

an integer vector specifying which side of the plot the axes are to be drawn on. The axes are placed as follows: 1 = below, 2 = left, 3 = above, and 4 = right.

twoPi

flag indicating that [0,2\pi) is the support, instead of [-\pi,\pi).

...

further parameters passed to axis.

Details

The function calls box.

Value

This function is usually invoked for its side effect, which is to add axes to an already existing plot.

Examples

grid <- seq(-pi, pi, l = 100)
plotSurface2D(grid, grid, f = function(x) sin(x[1]) * cos(x[2]),
              nLev = 20, axes = FALSE)
