In amt: Animal Movement Tools

Create an initial step for simulations

Description

An initial step for simulations. This step can either be created by defining a step from scratch or by using an observed step.

Usage

make_start(x, ...)

## S3 method for class 'numeric'
make_start(
  x = c(0, 0),
  ta_ = 0,
  time = Sys.time(),
  dt = hours(1),
  crs = NA,
  ...
)

## S3 method for class 'track_xyt'
make_start(x, ta_ = 0, dt = hours(1), ...)

## S3 method for class 'steps_xyt'
make_start(x, ...)

Arguments

x	⁠[steps_xyt,numeric(2)]⁠ A step of class steps_xyt or the start coordinates..
...	Further arguments, none implemented.
ta_	⁠[numeric(1)]{0}⁠ The initial turn-angle.
time	⁠[POSIXt(1)]{Sys.time()}⁠ The time stamp when the simulation starts.
dt	⁠[Period(1)]{hours(1)}⁠ The sampling rate of the simulations.
crs	⁠[int(1)]{NA}⁠ The coordinate reference system of the start location given as EPSG code.
