generate_subsamples {biosampleR}

Generate subsamples of a data frame with a number of sites between a minimum and maximum value.

Description

Generate subsamples of a data frame with a number of sites between a minimum and maximum value.

Usage

generate_subsamples(
  data,
  min_sites = 1,
  max_sites = nrow(data),
  step = 1,
  reps = 100,
  summary = TRUE,
  seed = sample(0:9999, 1)
)

Arguments

data

A data frame of count data, with sites as rows and species as columns.

min_sites

The minimum number of sites to include in a subsample.

max_sites

The maximum number of sites to include in a subsample. Defaults to the number of sites in the original data set.

step

The number of sites to increase by at each iteration.

reps

The number of subsamples with a given number of sites to create.

summary

A logical indicating whether to calculate summary indices using calc_diversity_indices. Defaults to TRUE.

seed

A random seed to use for reproducibility.

Value

A list of lists of data frames, if summary = FALSE, each data frame is a subsample of the original data set. If summary = TRUE, each data frame is a subsample of the original data set with diversity indices calculated using calc_diversity_indices.

Examples

ss <- generate_subsamples(BCI,
                          min_sites = 1,
                          max_sites = 5,
                          step = 1,
                          reps = 2)
