group_trends: Calculate group level trends

In CharlieOuthwaite/UKBiodiversity: Recreates analyses and figures of Outhwaite et al (in revision)

Description

This takes the posterior values of the group level indicators generated within the generage_fig1 function and calculates the group level average change and associated 95 accompanying paper.

Usage

group_trends(datadir, interval = 95)

Arguments

datadir	A filepath specifying where the posteior indicator values are saved. If outputs have not been moved, this will be in a directory "/MajorGroups/geomeans".
interval	A number between 0 and 100 indicating the percentiles of the credible intervals to be plotted and reported. Defaults to 95%.
