chainSawIZ(downLog,
           plotRadius,
           plotCenter = c(x=0, y=0),
           description = 'inclusion zone for "chainsaw" method',
           spID = unlist(strsplit(tempfile('cs:',''),'\/'))[2],
           spUnits = CRS(projargs=as.character(NA)),
           ... )

  • downLog: An object of class "'>downLog" which the inclusion zone is to be determined for under the chainsaw method.

  • plotRadius: The radius of the circular fixed-area plot in the correct units: feet for "English" and meters for "metric."

  • plotCenter: The (x,y) positions of the center of the circular plot that intersects the log forming the “sliver” that would be cut with a chainsaw at their intersection, and which will be sampled for volume. This should be a numeric vector of length 2 with names "x" and "y" (e.g., see circularPlot).

  • description: A character vector description of the object.

  • spID: A unique identifier that will be used in displaying the spatial polygon for the circular plot component of the object.

  • spUnits: A valid CRS object specifying the Coordinate Reference System. This defaults to NA, which means you want to use your own user-defined system, say for a sample plot located in the field.

  • dots: Arguments to be passed on.
