izGridMirage: Generate Objects of Class "'>mirageInclusionZoneGrid"

Description

This generic has one method that will create objects of class “mirageInclusionZoneGrid”. The normal use is through generation of a sampling surface, but the routine can be called as is to produce results for individual stem inclusion zones on a “mirageTract”.

Usage

izGridMirage(izObject, tract, ...)

Arguments

izObject

Signature object of a subclass of "'>InclusionZone".

tract

Signature object of class "'>mirageTract".

…

See izGridMirage-methods.

Value

A valid object of class "'>mirageInclusionZoneGrid."

Details

Objects of class “mirageInclusionZoneGrid” are farily complex and can hold information on external overlap areas is applicable. There is one method for this generic that can be used to create “mirageInclusionZoneGrid” object as described in izGridMirage-methods.

Examples

# NOT RUN {
tr = Tract(c(x=20,y=20), cellSize=1)
mtr = mirageTract(tr)
st = standingTree(centerOffset=c(x=16,y=16))
ag = angleGauge(4)     #4=baf
hps.iz = horizontalPointIZ(st, angleGauge=ag)
hps.izg = izGridMirage(hps.iz, mtr, truncateOverlap=FALSE)
plot(hps.izg, tract=mtr)
#now show external grid estimates...
plot(hps.izg, tract=mtr, showExtended = TRUE)
# }
