drawTrajectories: drawTrajectories

In pplane: Phase plane plots of 2D nonlinear systems

Description

evaluate and draw trajectories in the phase plane

Usage

drawTrajectories(fDeriv, tEnd = 1, tCut = 60, ..., tStart = 0, 


    x0 = list(x = c(1), y = c(1)), color = "black", arrowHeads = 0.06, 


    qArrow = 0.1, fLapply = lapply, fOde = deSolve::lsoda)

Arguments

fDeriv	derivative function function(x,y,...)
tEnd	numeric scalar: end time
tCut	numeric scalar: number of points of the trajectory
...	further arguments to fDeriv
tStart	start time
x0	list of starting positions, such as returned by locator(2,"p"), with entries x numeric vector of x positions y numeric vector of y positions
color	colour of the trajectory
arrowHeads	size of the arrow heads (in inches), set t0 0 to avoid
qArrow	quantile of the timepoints at which an arrow is drawn
fLapply	apply function (use sfLapply for parallel calculation of trajectories)
fOde	function to solve the forward problem

Value

invisible list of lsoda output for each trajectory
