horizontalPointCVIZ: Generate Objects of Class "'>horizontalPointCVIZ"

Description

This generic is the base constructor for creating objects of class “horizontalPointCVIZ”. Please see the associated horizontalPointCVIZ-methods method for more details.

Usage

horizontalPointCVIZ(standingTree, angleGauge, ...)

Arguments

standingTree

Signature object of class "'>standingTree".

angleGauge

Signature object of class "'>angleGauge".

…

See associated method.

Value

A valid object of class “horizontalPointCVIZ”.

Details

It is very important to note both here and in the method documentation that the call to this constructor is the appropriate place to include any extra arguments that should be passed on to the controlVariate constructor for control of subsampling within the inclusion zone. In addition, different proxy functions can have extra arguments associated with them beyond the three required ones. Again, this is the place to pass any of these extra arguments to the proxy functions. Please see getProxy for documentation on the built-in proxy functions, and note the different arguments associated with each function.

Examples

# NOT RUN {
#
# restrict CV sampling between 10-20m height and use the
# "wbProxy" function with solid type = 0.9*4 (close to true taper);
# with 2 subsamples to be taken on the tree at each grid cell...
#
st = standingTree(dbh=50, solidType=4, height=25)
ag = angleGauge(baf=4)
cvhps.iz = horizontalPointCVIZ(st, ag, segBnds=c(10,20),
           proxy='wbProxy', solidTypeProxy=0.9, n.s=2)
summary(cvhps.iz)
plot(cvhps.iz)
# }
