Plot an H2O Tabulate Heatmap

Source: R/models.R

Plots the simple co-occurrence based tabulation of X vs Y as a heatmap, where X and Y are two Vecs in a given dataset. This function requires suggested ggplot2 package.

# S3 method for H2OTabulate
plot(x, xlab = x$cols[1], ylab = x$cols[2], base_size = 12, ...)

Arguments

x

An H2OTabulate object for which the heatmap plot is desired.
xlab

A title for the x-axis. Defaults to what is specified in the given H2OTabulate object.
ylab

A title for the y-axis. Defaults to what is specified in the given H2OTabulate object.
base_size

Base font size for plot.
...

additional arguments to pass on.

Value

Returns a ggplot2-based heatmap of co-occurance.
