- formula
An R formula with additive effects. The `formula`

may contain
one or more invocations of the `stratify`

function whose
arguments are defined below. This causes
the entire analysis to be stratified by cross-classifications of the
combined list of stratification factors. This stratification will be
reflected as separate `lowess`

curves.

- data
name or number of a data frame. Default is the current frame.

- subset
a logical vector or integer vector of subscripts used to specify the
subset of data to use in the analysis. The default is to use all
observations in the data frame.

- na.action
function for handling missing data in the input data. The default is
a function defined here called `na.retain`

, which keeps all
observations for processing, with missing variables or not.

- fun
function for transforming `lowess`

estimates. Default is the
identity function.

- na.rm
`TRUE`

(the default) to exclude `NA`

s before passing data to
`fun`

to compute statistics, `FALSE`

otherwise.

- ylab
`y`

-axis label. Default is label attribute of
`y`

variable, or its name.

- ylim
`y`

-axis limits. By default each graph is scaled on
its own.

- xlim
a list with elements named as the variable names appearing
on the `x`

-axis, with each element being a 2-vector specifying
lower and upper limits. Any variable not appearing in the list will
have its limits computed and possibly `trim`

med.

- nloc
location for sample size. Specify `nloc=FALSE`

to
suppress, or `nloc=list(x=,y=)`

where `x,y`

are relative
coordinates in the data window. Default position is in the largest
empty space.

- datadensity
see `plsmo`

. Defaults to `TRUE`

if there is a `stratify`

variable, `FALSE`

otherwise.

- quant
vector of quantiles to use for summarizing the marginal distribution
of each `x`

. This must be numbers between 0 and 1
inclusive. Use `NULL`

to omit quantiles.

- quantloc
specify `quantloc='bottom'`

to place at the
bottom of each plot rather than the default

- cex.quant
character size for writing which quantiles are
represented. Set to `0`

to suppress quantile labels.

- srt.quant
angle for text for quantile labels

- bpplot
if not `'none'`

will draw extended box plot at
location given by `bpplot`

, and quantiles discussed above will
be suppressed. Specifying `bpplot='top'`

is the same as
specifying `bpplot='top inside'`

.

- height.bpplot
height in inches of the horizontal extended box plot

- trim
The default is to plot from the 10th smallest to the 10th
largest `x`

if the number of non-NAs exceeds 200, otherwise to
use the entire range of `x`

. Specify another quantile to use
other limits, e.g., `trim=0.01`

will use the first and last
percentiles

- test
Set to `TRUE`

to plot test statistics (not yet implemented).

- vnames
By default, plots are usually labeled with variable labels
(see the `label`

and `sas.get`

functions). To use the shorter
variable names, specify `vnames="names"`

.
