makeTriData: make some fake data

In barryrowlingson/telemetr: Radio Direction-finding Telemetry code

Description

make some fake data

Usage

  makeTriData(ntowers, xlim = c(0, 1), ylim = c(0, 1),
    noise = 5)

Arguments

ntowers	number of towers
xlim	x range
ylim	y range
noise	angular noise in degrees Place a critter at a random uniform point in the xlim,ylim box. Place ntowers randomly uniform in the box. Compute angles from the towers to the critter. Add some random normal angular noise with mean 0 and se=noise to the angles to get the simulated bearings.

Value

a data frame with x, y, thetaTrue, bearing, and theta values. It also has a 'critter' attribute which is the true location of the critter. Note that thetaTrue and theta are conventional angles from the x=0 line, and bearing is a reading in degrees from North.
