Plot Method for MVR objects

Description

plot.mvr plots predictions, coefficients, scores, loadings, biplots or validation plots (RMSEP curves, etc.).

Usage

## S3 method for class 'mvr':
plot(x, plottype = c("prediction", "validation", "coefficients",
                     "scores", "loadings", "biplot"), ...)

Arguments

x an object of class mvr. The fitted model to plot.
plottype character. What kind of plot to plot.
... further arguments, sent to the underlying plot functions.

Details

The function is simply a wrapper for the underlying plot functions used to make the selected plots. See predplot.mvr, validationplot, coefplot, scoreplot, loadingplot or biplot.mvr for details. Note that all arguments except x and plottype must be named.

Value

plot.mvr returns whatever the underlying plot function returns.

Examples

data(NIR)
nir.pcr <- pcr(y ~ X, ncomp = 9, data = NIR, CV = TRUE)
## Not run: plot(nir.pcr, ncomp = 5) # Plot of cross-validated predictions
## Not run: plot(nir.pcr, "scores") # Score plot
## Not run: plot(nir.pcr, "loadings", comps = 1:3) # The three first loadings
## Not run: plot(nir.pcr, "coef", ncomp = 5) # Coefficients
## Not run: plot(nir.pcr, "val") # RMSEP curves
## Not run: plot(nir.pcr, "val", val.type = "MSEP", estimate = "CV") # CV MSEP
