Momocs (version 1.0.0)

plot_CV: Plots a cross-validation table as an heatmap

Description

Either with frequencies (or percentages) plus marginal sums, and values as heatmaps. Used in Momocs for plotting cross-validation tables but may be used for any table (likely with freq=FALSE).

Usage

plot_CV(x, ...)
"plot_CV"(x, freq = TRUE, rm0 = TRUE, cex = 5, round = 2, labels = TRUE, ...)
"plot_CV"(x, freq = TRUE, rm0 = TRUE, cex = 5, round = 2, labels = TRUE, ...)

Arguments

x

a (cross-validation table) or an LDA object

...

only used for the generic

freq

logical whether to display frequencies or counts

rm0

logical whether to remove zeros

cex

numeric to adjust labels in every cell. NA to remove them

round

numeric, when freq=TRUE how many decimals should we display

labels

logical whether to display freq or counts as text labels

Value

a ggplot object

See Also

LDA, plot.LDA, and (pretty much the same) Ntable.

Examples

data(olea)
ol <- LDA(PCA(opoly(olea, 5)), "domes")
gg <- plot_CV(ol) # just a wrapper for plot_CV(ol$CV.tab) though
