chainSawIZ-methods: Method for "chainSawIZ" object construction in Package...

Description Methods


This is the one methods for generic function chainSawIZ in Package ‘sampSurf’ that allows for creation of objects of class "chainSawIZ."


signature(downLog = "downLog", plotRadius = "numeric")


           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.
