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,
		xlab="", ylab="", title=NA, ...)

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

xlab

Label on the X-axis.

ylab

Label on the Y-axis.

title

Title of the Plot. If not provided, the title is constructed automatically from 'mode' argument.

...

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