##### Enhanced Dot Chart

dotchart2 is an enhanced version of the dotchart function with several new options.

Keywords
hplot
##### Usage
dotchart2(data, labels, groups, gdata, horizontal=TRUE, pch=16,
xlab='', ylab='', auxdata, auxgdata=NULL, auxtitle,
lty=if(.R.) 1 else 2, lines=TRUE, dotsize = .8,
cex = par("cex"), cex.labels = cex,
cex.group.labels = cex.labels*1.25, sort.=TRUE,
lcolor=if(.R.)'gray' else par('col'), ...)
##### Arguments
data
a numeric vector whose values are shown on the x-axis
labels
a vector of labels for each point, corresponding to x. If omitted, names(data) are used, and if there are no names, integers prefixed by "#" are used.
groups
an optional categorical variable indicating how data values are grouped
gdata
data values for groups, typically summaries such as group medians
horizontal
set to FALSE to make the chart vertical instead of the default
pch
default character number or value for plotting dots in dot charts. The default is 16.
xlab
x-axis title
ylab
y-axis title
auxdata
a vector of auxiliary data given to dotchart2, of the same length as the first (data) argument. If present, this vector of values will be printed outside the right margin of the dot chart. Usually auxdata repres
auxgdata
similar to auxdata but corresponding to the gdata argument. These usually represent overall sample sizes for each group of lines.
auxtitle
if auxdata is given, auxtitle specifies a column heading for the extra printed data in the chart, e.g., "N"
lty
line type for horizontal lines. Default is 1 for R, 2 for S-Plus
lines
set to FALSE to suppress drawing of reference lines
dotsize
cex value for drawing dots. Default is 0.8. Note that the original dotchart function used a default of 1.2.
cex
see par
cex.labels
cex parameter that applies only to the line labels for the dot chart cex parameter for major grouping labels for dotchart2. Defaults to cex.
cex.group.labels
value of cex corresponding to gdata
sort.
set to FALSE to keep dotchart2 from sorting the input data, i.e., it will assume that the data are already properly arranged. This is especially useful when you are using gdata and groups and you wan
set to TRUE to add to an existing plot
dotfont
font number of plotting dots. Default is one. Use -1 to use "outline" fonts. For example, pch=183, dotfont=-1 plots an open circle for UNIX on postscript. pch=1 makes an open octagon under Windows.
groupfont
font number to use in drawing group labels for dotchart2. Default is 5 for UNIX, which is usually Helvetica bold. For Microsoft Windows, the default is 1. The font number corresponding to some bold
reset.par
set to FALSE to cause dotchart2 to not reset the par parameters when finished. This is useful when add=TRUE is about to be used in another call. The default is to reset the par paramete
xaxis
set to FALSE to suppress drawing x-axis
width.factor
When the calculated left margin turns out to be faulty, specify a factor by which to multiple the left margin as width.factor to get the appropriate space for labels on horizonal charts.
lcolor
color for horizontal reference lines. Default is "gray" for R, par("col") for S-Plus.
...
arguments passed to plot.default
##### Side Effects

dotchart will leave par altered if reset.par=FALSE.
