draw.xvalid {RGeostats}R Documentation

Graphic representation of Cross-Validation results

Description

Graphic representation of Cross-Validation results

Usage

draw.xvalid(db, mode = 1, name.data   = NA, name.estim  = db.ident(db,"*.estim"),
		name.stderr = db.ident(db,"*.stderr"), thresh = 2.5, nbins = 20, ...)

Arguments

db

The db-class containing the cross-validation results

mode

Type of graphic representation:

  • 1 Base Map showing the absolute value of the Standardized Error in proportional symbol. Samples for which this value is larger than the threshold 'thresh' are represented in solid red points.

  • 2 Histogram of the Standardized Error. Bins corresponding to values beyond the threshold are represented in red.

  • 3 Scatter plot of the Standardized Error vs. the Estimation.

  • 4 Scatter plot of the true data vs. the Estimation

name.data

Name of the variable containing the input variable that has just be checked using the cross-validation procedure. If this variable is not provided the plot corresponding to mode=4 is not performed

name.estim

Name of the variable containing the cross-validation Estimation

name.stderr

Name of the variable containing the cross-validation Standardized Error

thresh

Value of the threshold

nbins

Number of bins used for the representation of the Histogram of the Standardized Errors

...

Additional arguments passed to db.plot, hist and correlation.
