An extension of barplot2. Creates bar- and line-plots mimicking the style of OpenOffice plots. This utility can plot the values next to each point or bar as well as confidence intervals.

``` |

`data` |
a matrix of values describing the values that make up the
plot. The first column of |

`width` |
optional vector of barwidths. Re-cycled to the number of bars drawn. A single value will have no visible effect. |

`space` |
the amount of space left before each bar. May be given
as a single number or one number per bar. If |

`names.arg` |
a vector of names to be plotted below each bar or
group of bars. If this argument is omitted, then the names are
taken from the row names of |

`legend.text` |
a vector of text used to construct a legend for the
plot, or a logical indicating whether a legend should be included;
if |

`horiz` |
a logical value. If |

`density` |
a vector giving the the density of shading lines, in
lines per inch, for the bars or bar components.
The default value of |

`angle` |
the slope of shading lines, given as an angle in degrees (counter-clockwise), for the bars or bar components. |

`kmg` |
the set of SI units to convert, defaults to "fpnumkMGTP". See below for details. |

`kmglim` |
logical. If |

`type` |
a string indicating the preferred format of the plot, choices are: xyplot : plot where y is plotted against the x-value. linear : plot where y values are plotted against equidistant x-values. barplot : plot where y values are represented as bars against equidistant x-values. stackplot : plot where y values are stacked for identical x-values and bars are equidistant. |

`col` |
a vector of colors for the bars or bar components. |

`prcol` |
the color to be used for the plot region. |

`border` |
the color to be used for the border of the bars. |

`main, sub` |
overall and sub titles for the plot. |

`xlab` |
a label for the x axis. |

`ylab` |
a label for the y axis. |

`xlim` |
limits for the x axis. |

`ylim` |
limits for the y axis. |

`xpd` |
logical. Should bars be allowed to go outside region? |

`log` |
a character string which contains ‘"x"’ if the x axis is to be logarithmic, ‘"y"’ if the y axis is to be logarithmic and ‘"xy"’ or ‘"yx"’ if both axes are to be logarithmic. |

`axes` |
logical. If |

`axisnames` |
logical. If |

`prval` |
logical. If |

`lm` |
logical. If |

`cex.axis, cex.names, cex.values` |
character scaling factor for numeric axis labels, names, and displayed values, respectively. |

`inside` |
logical. If |

`plot` |
logical. If |

`axis.lty` |
the graphics parameter |

`plot.ci` |
logical. If |

`ci.l,ci.u` |
The confidence intervals (ci.l = lower bound, ci.u =
upper bound) to be plotted if |

`ci.color` |
the color for the confidence interval line segments |

`ci.lty` |
the line type for the confidence interval line segments |

`ci.lwd` |
the line width for the confidence interval line segments |

`plot.grid` |
if |

`grid.inc` |
the number of grid increments to be plotted |

`grid.lty` |
the line type for the grid |

`grid.lwd` |
the line width for the grid |

`grid.col` |
the line color for the grid |

`add` |
logical, if |

`by.row` |
Logical value. If |

`...` |
further graphical parameters ( |

Plot units are automatically scaled to SI units based on the
maximum value present, according to the set of units specified by
characters in the `kmg`

parameter. These letters are interpreted
as

- P
peta = 1E15

- T
tera = 1E12

- G
giga = 1E09

- M
mega = 1E06

- k
kilo = 1E03

- m
milli= 1E-03

- u
micro= 1E-06

- n
nano = 1E-09

- p
pico = 1E-12

- f
femto= 1E-15

with the default being "fpnumkMGTP" (all of these units). For example, if the largest value plotted is 1243000, it would be presented as 1.234M.

A numeric vector (or matrix, when `beside = TRUE`

), say
`mp`

, giving the coordinates of *all* the bar midpoints
drawn, useful for adding to the graph.

If `beside`

is true, use `colMeans(mp)`

for the
midpoints of each *group* of bars, see example.
