Calculate the proportion of fibers in a microplastic particle collective
Description
This functions computes the proportion of fibers in a microplastic particle collective.We use one of two different
shape descriptors as a criterion. For an aspect ratio larger than 3 MP is considered a fiber based on Cole (2016).
This is equal to an elongation larger than 2/3.Note that elongation must be calculated according to Crompton (2005).
Usage
calc_proportion_ofFibers(shape, criterion = "elon")
Arguments
shape
A character string to select the vector that contains either aspect ratio or elongation values.
criterion
A character string indicating whether aspect ratio or elongation should be used to calculate the proportion. Must be either "asp" or "elon". Default is "elon".
data
A data frame that will be manipulated.
