get_dyadic_observations: For each dyad within each time period, this function counts...

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

Description

Furthermore, this function conducts pre-network data permutations 'n_permutations' times (0 for no permutations) using the function 'permute_scan_data' For each permutation, 'flips_per_permutation' NNs are flipped. Then, the number of times Individual B was recorded as NN of Individual A is counted ('$n_Ind_NN_together_permuted')

Usage

get_dyadic_observations(
  ind_nn_df,
  presence_df,
  i_obs_min = 5,
  max_nn_dist = 5,
  n_permutations = 0,
  set_seed = 1209,
  ind_sex_permutation = c("Male", "Female"),
  nn_sex_permutation = c("Male", "Female"),
  flips_per_permutation = 1,
  ...
)

Arguments

ind_nn_df	Data frame with information on indviduals and nearest neighours from red colobus scan data. Created with 'prep_red_colobus_ind_nn_data()'
presence_df	Dataframe created with 'get_presence_rc'
max_nn_dist	The maximum distance for which an individual is still considered NN. Default is 5 (m)
n_permutations	How many permutations should be conducted?
ind_sex_permutation	default 'c("Male", "Female")'
nn_sex_permutation	default 'c("Male", "Female")'
flips_per_permutation	Number of iterations ('NN flips') per permutation

Details

Limitations: This function cannot (yet) permute within sex classes only. To achieve that, subset scandata and only include females or males before running the function. Set 'ind_sex_permutation' and 'nn_sex_permutation' to "Male"/"Female" respectively (although this should be working with default arguments)
