stripchart
produces one dimensional scatter plots (or dot
plots) of the given data. These plots are a good alternative to
boxplot
s when sample sizes are small.

## S3 method for class 'formula'
stripchart(x, data = NULL, dlab = NULL, ...,
subset, na.action = NULL)
## Default S3 method:
stripchart(x, method = "overplot", jitter = 0.1, offset = 1/3,
vertical = FALSE, group.names, add = FALSE,
at = NULL, xlim = NULL, ylim = NULL,
ylab = NULL, xlab = NULL, dlab = "", glab = "",
log = "", pch = 0, col = par("fg"), cex = par("cex"),
axes = TRUE, frame.plot = axes, ...)

x 
the data from which the plots are to be produced. In the
default method the data can be specified as a single numeric
vector, or as list of numeric vectors, each corresponding to
a component plot. In the 
data 
a data.frame (or list) from which the variables in

subset 
an optional vector specifying a subset of observations to be used for plotting. 
na.action 
a function which indicates what should happen
when the data contain 
... 
additional parameters passed to the default method, or by
it to 
method 
the method to be used to separate coincident points.
The default method 
jitter 
when 
offset 
when stacking is used, points are stacked this many lineheights (symbol widths) apart. 
vertical 
when vertical is 
group.names 
group labels which will be printed alongside (or underneath) each plot. 
add 
logical, if true add the chart to the current plot. 
at 
numeric vector giving the locations where the charts should
be drawn, particularly when 
ylab, xlab 
labels: see 
dlab, glab 
alternate way to specify axis labels: see ‘Details’. 
xlim, ylim 
plot limits: see 
log 
on which axes to use a log scale: see

pch, col, cex 
Graphical parameters: see 
axes, frame.plot 
Axis control: see 
Extensive examples of the use of this kind of plot can be found in Box, Hunter and Hunter or Seber and Wild.
The dlab
and glab
labels may be used instead of xlab
and ylab
if those are not specified. dlab
applies to the
continuous data axis (the X axis unless vertical
is TRUE
),
glab
to the group axis.
