Reviewing

I’ve been a reviewer for many scientific journals.

entropart

entropart is an R package that provides functions to calculate alpha, beta and gamma diversity of communities, including phylogenetic and functional diversity. Estimation-bias corrections are available.

dbmss

dbmss is an R package for simple computation of spatial statistic functions of distance to characterize the spatial structures of mapped objects, including classical ones (Ripley’s \(K\) and others) and more recent ones used by spatial economists (Duranton and Overman’s \(K_d\), Marcon and Puech’s \(M\)). It relies on spatstat for some core calculation.
