R Documentation

Bar Plots

Description

Create bar plots for one or two factors scaled by frequency or precentages. In the case of two factors, the bars can be divided (stacked) or plotted in parallel (side-by-side). This function is a front end to barplot in the graphics package.

Usage

Barplot(x, by, scale = c("frequency", "percent"), 
  style = c("divided", "parallel"), col = rainbow_hcl(length(levels(by))), 
  xlab = deparse(substitute(x)), legend.title = deparse(substitute(by)), 
  ylab = scale, legend.pos = "topright", ...)

Arguments

`x`	a factor.
`by`	optionally, a second factor.
`scale`	either `"frequency"` (the default) or `"percent"`.
`style`	for two-factor plots, either `"divided"` (the default) or `"parallel"`.
`col`	colors for the `by` factor in two-factor plots; defaults to colors provided by `rainbow_hcl` in the colorspace package.
`xlab`	an optional character string providing a label for the horizontal axis.
`legend.title`	an optional character string providing a title for the legend.
`ylab`	an optional character string providing a label for the vertical axis.
`legend.pos`	position of the legend, in a form acceptable to the `legend` function.
`...`	arguments to be based to the `barplot` function.

Value

Returns NULL invisibly.
