Histogram from tabulated data

Uses lattice::barchart() to build a histogram from tabulated data.

Usage

histochart(
  x,
  data = NULL,
  box.ratio = 100,
  origin = 0,
  horizontal = FALSE,
  ...
)

Arguments

x

formula of form frequency ~ value

data

data frame in which the formula x is interpreted

box.ratio

ratio of bar widths to gaps between bars

origin

where do bars begin?

horizontal

Should bars go horizontal?

...

other arguments passed to lattice::barchart()

Details

This is just a convenience wrapper around lattice::barchart().
