makeMoreTriData: make some fake data for a number of groups
In barryrowlingson/telemetr: Radio Direction-finding Telemetry code

Description Usage Arguments Value

make some fake data for a number of groups

1 2	makeMoreTriData(ntowers = 3, animals = 1:4, dates = as.Date("2001/12/1") + 0:1)

ntowers

number of towers giving readings in each group

animals

a group variable, typically animal id

dates

a date

for each unique combination of animal and date, we call makeTriData and return a spatial points data frame with the animal and date variables as well as the true and noisy directions. The coordinates of the critter are not preserved (but can be got pretty accurately from the thetaTrue values and at least two readings)

A Spatial Points Data Frame of simulated data.
