Geom.histogram

Draw histograms. An alias for Geom.bar with Stat.histogram.

Aesthetics

• x: Sample to draw histogram from.

• color (optional): Group categoricially by color.

Arguments

• position: Either :stack or :dodge. If the color aesthetic is bound this determines how bars of different colors should be arranged: stacked on top of each other, or placed side by side.

• orientation: Either :vertical (default) or :horizontal. If :horizontal, then the required aesthetic is y instead of x.

• bincount: Number of bins to use. If unspecified, an optimization method is used to determine a reasonable value.

• minbincount: Set a lower limit when automatically choosing a bin count.

• maxbincount: Set an upper limit when automatically choosing a bin count.

• density: If true, use density rather that counts.

Examples

plot(dataset("ggplot2", "diamonds"), x="Price", Geom.histogram)

# Binding categorical data to color
plot(dataset("ggplot2", "diamonds"), x="Price", color="Cut", Geom.histogram)

# Choosing a smaller bin count
plot(dataset("ggplot2", "diamonds"), x="Price", color="Cut",
     Geom.histogram(bincount=30))

# Density instead of counts
plot(dataset("ggplot2", "diamonds"), x="Price", color="Cut",
     Geom.histogram(bincount=30, density=true))
