plot.mvr: Plot Method for MVR objects

Description

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

Usage

# S3 method for mvr
plot(x, plottype = c("prediction", "validation", "coefficients",
                     "scores", "loadings", "biplot", "correlation"), …)

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.

Value

plot.mvr returns whatever the underlying plot function returns.

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, biplot.mvr or corrplot for details. Note that all arguments except x and plottype must be named.

Examples

# NOT RUN {
data(yarn)
nir.pcr <- pcr(density ~ NIR, ncomp = 9, data = yarn, validation = "CV")
# }
# NOT RUN {
plot(nir.pcr, ncomp = 5) # Plot of cross-validated predictions
plot(nir.pcr, "scores") # Score plot
plot(nir.pcr, "loadings", comps = 1:3) # The three first loadings
plot(nir.pcr, "coef", ncomp = 5) # Coefficients
plot(nir.pcr, "val") # RMSEP curves
plot(nir.pcr, "val", val.type = "MSEP", estimate = "CV") # CV MSEP
