Select frequency in cross table #49

Open kamapu opened 8 months ago

kamapu commented 8 months ago

Add argument min_freq in crosstable() allowing to filter rare species in the same step.

This feature is not feasible in this form. Instead, an additional function (e.g. sort_by_freq()) needs to be designed with following parameters:

formula (used to aggregate and indicating the taxonomic rank.
data (vegtable object but maybe also a matrix)
decreasing allowing decreasing sorting of taxa
logical expression, for instance to select by frequency values

This function won't only calculate frequencies but sort them and select according to the expression.
