calculateCrowding: Calculate crowding statistics

In MarcoDVisser/FDPtools: Optimized tools for working with forest dynamics plot data

Description

calculateCrowding - Calculates crowding statistics for each individual alive, based on the surrounding environment, in each included census for the BCI plot data. Alternatively, if a second data set is included (refdata) it calculates crowding statistics for all points in the second dataset based on all points in each FDP census included.

Usage

calculateCrowding(FdpData = list(bci.full6, bci.full7), refdata = NULL,
  r = seq(1, 50, 10), statistic = "count", ...)

Arguments

FdpData	A list of fdp census datasets on which the calculation must be conducted
refdata	a second dataset including points for which crowding statistics based on the FdpData must be calculated. This option is ignored if NULL.
r	a vector containing all distances at which the below statistic must be calculated. Used if relevant.
...	further arguments to be passed to statistic calculation
statsistic	character defining which method to use. Methods include: 1) "count", simple count of neighbours within r 2) "distance index", a distance weighted function 3) "gravitation", a size and distance weighted function
