draw_random_path_section: Draw a random path section.

In a-parton/CTStepTurn: Fitting the continuous-time step-and-turn movement model

Description

draw_random_path_section returns details on a randomly selected section of path to update.

Usage

draw_random_path_section(section_length_limits, obs_index)

Arguments

section_length_limits	Vector of length two, lower and upper length limits for the section to choose.
obs_index	Vector of length number of observations, giving the index on the refined path where observation times coincide.

Value

List with components:

start

Numeric, the index of the start of chosen section.

end

Numeric, the index of the end of chosen section.

contained_obs_index

Vector (length variable) of index which are also observations (within the section).

contained_obs

Vector (length variable) of observation indexs included in the section.
