Given a spatially explicit data frame of individual locations in a simulated arena, and the bounds of a series of plots, identifies the contents of each plot.
1 | plotContents(arena, plotPlacer.results)
|
arena |
Data frame of three columns: "individuals", "X", and "Y" |
plotPlacer.results |
The results of a call to plotPlacer. A list with two elements. The first is a matrix of X Y coordinates of plots. The second is a symmetrical distance matrix summarizing the distances among these plots. |
Takes a data frame like that returned from filteringArena(), and a matrix like that returned from plotPlacer(), and returns the resulting community data matrix such as might be generated by someone surveying a forest plot. Plots with < 2 species are excluded from the CDM.
A matrix with species as rows and plots as columns.
