In this research, we present a comprehensive, longitudinal empirical summary of the R package ecosystem, including not just CRAN, but also Bioconductor and GitHub. We analyze more than 25,000 packages, 150,000 releases, 15 million files across two decades, providing comprehensive counts trends for common metrics authors, licenses, other important metadata. find that historical growth ecosystem ...

Aim Mechanistic general ecosystem models are used to explore fundamental ecological dynamics and assess possible consequences of anthropogenic natural disturbances on ecosystems. The Madingley model is a mechanistic (GEM) that simulates coherent global ecosystem, consisting photo-autotrophic heterotrophic life, based processes. C++ implementation the delivers fast computational performance, but...

Categorical functional data represented by paths of a stochastic jump process with continuous time and finite set states are considered. As an extension the multiple correspondence analysis to infinite variables, optimal encodings over approximated using arbitrary basis functions. This allows dimension reduction, representation, visualisation in lower dimensional spaces. The methodology is impl...

Log Size Indexes (LSI) allow the increase of number data and have been used in a zooarchaeological studies since 1950. However, some standards to calculate log ratios remain unpublished, calculation indexes can be tedious, it is further hindered by diversity recording practices. The R package ‘zoolog’ enables thousands log-ratios seconds, with advantage that users choose between different publi...
