permute_scan_data: Permutation of Nearest Neighbours in Red Colobus scan data:...

In urskalbitzer/daginR: Analyses of Monkey Data from Scan and Focal Samples

Description

It does so by choosing a random line from the scan data, and then checks if Individual (1) and NN (1) are both adult and have the sex according to arguments 'ind_sex_permutation' and 'nn_sex_permutation'.

Usage

permute_scan_data(
  ind_nn_single_timeperiod,
  presence_df,
  ind_sex_permutation = c("Male", "Female"),
  nn_sex_permutation = c("Male", "Female"),
  flips_per_permutation,
  show_i = FALSE
)

Arguments

ind_nn_single_timeperiod	based on ind_nn_df created with 'prep_red_colobus_ind_nn_data()'
presence_df	Dataframe created with 'get_presence_rc'
ind_sex_permutation	default 'c("Male", "Female")'
nn_sex_permutation	default 'c("Male", "Female")'
flips_per_permutation	Number of iterations ('NN flips') per permutation
show_i	Show progress

Details

Then, a second (random) row is chosen, and the same checks are done for Individual (2) and NN (2). Furthermore, it is controlled that NN1 was present at date of second row, and NN2 present at date of first row.

If these conditions are met, the two NNs are flipped.

This procedure is repeated 'flips_per_permutation' times.
