In klvoje/evoTS: Analyses of Evolutionary Time-Series

#' Evolutionary sequence (time-series) of phenotypic change in the number of ribs in the lineage Stephanodiscus yellowstonensis
#'
#' Phenotypic data (ribs) from a centric diatom lineage Stephanodiscus yellowstonensis. The time series spans about 14 000 years.
#' The data set contains data on the number of costae (ribs) per valve.
#' The data consists of an objects of class paleoTS (ribs_S.yellowstonensis). Objects of class paleoTS can be analyzed in evoTS.
#' The object (trait data set) contains a vector of sample means (mm), sample variances (vv), sample sizes (nn) and sample ages (tt).
#' The oldest sample is listed first. The data spans an interval of 13728 years.
