Description
{RRatepol} is an R package for estimating rate of change (RoC) from community data in time series.
{RRatepol} is written as an R package and includes a range of possible settings including a novel method to evaluate RoC in a single stratigraphical sequence using assemblage data and age uncertainties for each level. There are multiple built-in dissimilarity coefficients (dissimilarity_coefficient) for different types of assemblage data, and various levels of data smoothing that can be applied depending on the type and variance of the data. In addition, {RRatepol} can use randomisation, accompanied by use of age uncertainties of each level and taxon standardisation to detect RoC patterns in datasets with high data noise or variability (i.e. numerous rapid changes in composition or sedimentation rates).

Workshop on R-Ratepol
On the 28th of April, 2023, I organized together with Ondřej Mottl a workshop on the use of R-Ratepol for fossil pollen records, here specifically for researchers of the African Pollen Database.
