##### Create an OpenOffice style plot

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.

##### Arguments
data

a matrix of values describing the values that make up the plot. The first column of data is taken as the axis against which all the other values are plotted. The first column of data may not be sparse.

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 type is stackbar, space may be specified by two numbers, where the first is the space between bars in the same group, and the second the space between groups. Defaults to c(0,1) if type is a stackbar, and to 0.2 otherwise.

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 data.

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 legend.text is true, the row names of data will be used as labels if they are non-null.

horiz

a logical value. If FALSE, the bars are drawn vertically with the first bar to the left. If TRUE, the bars are drawn horizontally with the first at the bottom.

density

a vector giving the the density of shading lines, in lines per inch, for the bars or bar components. The default value of NULL means that no shading lines are drawn. Non-positive values of density also inhibit the drawing of shading lines.

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 FALSE the conversion to SI units is not performed. Default is TRUE.

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 TRUE, a vertical (or horizontal, if horiz is true) axis is drawn.

axisnames

logical. If TRUE, and if there are names.arg (see above), the other axis is drawn (with lty=0) and labeled.

prval

logical. If TRUE, then values are plotted above all points and bars.

lm

logical. If TRUE, the linear fit is plotted.

cex.axis, cex.names, cex.values

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

inside

logical. If TRUE, the lines which divide adjacent (non-stacked!) bars will be drawn. Only applies when space = 0 (which it partly is when beside = TRUE).

plot

logical. If FALSE, nothing is plotted.

axis.lty

the graphics parameter lty applied to the axis and tick marks of the categorical (default horzontal) axis. Note that by default the axis is suppressed.

plot.ci

logical. If TRUE, confidence intervals are plotted over the bars. Note that if a stacked bar plot is generated, confidence intervals will not be plotted even if plot.ci = TRUE

ci.l,ci.u

The confidence intervals (ci.l = lower bound, ci.u = upper bound) to be plotted if plot.ci = TRUE. Values must have the same dim structure as height.

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 TRUE a lined grid will be plotted behind the bars

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

logical, if TRUE add barplot to current plot.

by.row

Logical value. If TRUE the data matrix is organized with variables along rows rather than down colums.

further graphical parameters (par) are passed to plot.window(), title() and axis.

##### Details

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.

##### Value

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.
