FShake3D: Create density surface with mouse manipulations
In dill/wisp: Wildlife Simulation Package (wisp)

Description Usage Arguments Details Value Note Author(s) See Also Examples

By pulling on nodes throughout the study region, the user can create a density surface from which the simulated animal population is generated with the use of a mouse. This can make creation of a complex density surface much more rapid than repeated use of add.hotspot and set.stripe.

1	run.FShake3D(xlim = c(-1, 1), ylim = c(-1, 1), nx = 10, ny = 10)

`xlim`	Limits of study region in x-dimension
`ylim`	Limits of study region in y-dimension
`nx`	Number of manipulable nodes along the x-dimension
`ny`	Number of manipulable nodes along the y-dimension

Makes call to C++ code to perform the actual surface manipulation.

An object of class 'density.population´ which has the following elements:

`n.interval.x`	number of x-intervals
`n.interval.y`	number of y-intervals
`matrix`	the density matrix.

#		Because function uses the mouse, can only be done when interactive
if (interactive()) {
	run.FShake3D(xlim = c(-1, 1), ylim = c(-1, 1), nx = 10, ny = 10)
