In forestgeo/ctfs: Tools for the Analysis of Forest Dynamics

Description

Calculate indices of neighboring quadrats, for a given quadrat index.

Usage

findborderquads(index, dist = 20, gridsize = 20, plotdim = c(1000,
  500))

Arguments

index	Quadrate number, between 0 and 1249 in the standard plot.
dist	Distance in m within which the neighboring quadrates are located. Distance is measured from any side of the index quadrate.
gridsize	Side of the square quadrate.
plotdim	The x and y dimensions of the plot.

Details

Standard plotdim dimensions is : east-west 1000m and north-south 500m, and standard gridsize is 20 x 20m by default.

Value

A vector of numbers, the quadrate indices for all surrounding quadrates.
