Barplot: 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.

Value

• Returns NULL invisibly.
