sim_selection_weights: Create parameters and simulate selection weights

Description

This function creates and explores parameters for generating selections. These parameters define the selection distribution of minutes (min) around the sun event (sunrise/sunset), as well as of days (day).

Usage

sim_selection_weights(
  min_range = c(-70, 240),
  min_mean = 30,
  min_sd = 60,
  day_range = c(120, 201),
  day_mean = 161,
  day_sd = 20,
  offset = 0,
  return_log = TRUE,
  selection_fun = "norm",
  selection_var = "psel_normalized",
  return_params = TRUE,
  plot = TRUE
)

Value

Returns either a list of selection parameters or a plot of simulated selection weights

Arguments

min_range

Numeric vector. Range of the sampling distribution of minutes around the sun event.

min_mean

Numeric. Mean of the sampling distribution of minutes to the sun event.

min_sd

Numeric. SD in minutes of the sampling distribution of minutes around the sun event.

day_range

Date/Datetime/Numeric vector. Range of sampling distribution of days. Can be Dates, Date-times, or DOY (day-of-year, 1-366).

day_mean

Date/Datetime/Numeric. Mean date of the sampling distribution of days. Can be Date, Date-time, or DOY (day-of-year, 1-366).

day_sd

Numeric. SD in days of the sampling distribution of days.

offset

Numeric. Offset to shift for time of day in minutes.

return_log

Logical. Log the density in the selection function?

selection_fun

Character. Selection function to use. Options are lognorm, norm (default), or cauchy.

selection_var

Character. Selection variable to plot (if plot = TRUE). Options are are psel, psel_doy, psel_min, psel_std, psel_scaled, or psel_normalized (default).

return_params

Logical. Return parameter list for use in calc_selection_weights()?

plot

Logical. Create plot of simulated selection weights? If return_param = TRUE and plot = TRUE plot is created as a side effect. Other wise, plot is returned directly.

Examples

params <- sim_selection_weights()
