An R platform for computing competition indices and experimenting with spatially explicit individual-based vegetation models.
Current stable siplab version 1.6 on CRAN: https://cran.r-project.org/package=siplab
Install the stable version from CRAN: install.packages("siplab")
\
or with the RStudio menus: Tools > Install Packages... > siplab
For testing the bleeding-edge development version from here use devtools::install_github("ogarciav/siplab")
Computing Hegyi's competition index:
hegyi <- pairwise(spruces, maxR=6, kernel=powers_ker,
kerpar=list(pi=1, pj=1, pr=1, smark=1))
head(marks(hegyi))
Areas of Brown's APAs (aka Dirichlet cells or Voronoi polygons):
trees <- spruces
marks(trees) <- 100
apa <- assimilation(trees)
summary(marks(apa))
