Taxa in the assemblage dataset can be standardised to a certain count
(e.g. number of pollen grains in each WU) by rarefaction. Random sampling
without replacement is used to draw a selected number of individuals from
each WU (e.g. 150 pollen grains).
Usage
standardise_community_data(data_source_standard, n_individuals = 150)
Arguments
- data_source_standard
Data.frame with taxons as columns
- n_individuals
Numeric. Number of grain to perform standardisation to.
The N_individual is automatically adjusted to the smallest number
of pollen grains in sequence.
