...)A vector of strings containing variable names for the scatterplot matrix.
An "xpose.data" object.
A vector of strings containing labels for the variables in the scatterplot matrix.
A logical value indicating whether rows with WRES=0 should be plotted.
A logical value indicating whether only the first row per individual should be included in the plot.
The name of the panel function to use.
logical variable specifying whether a linear regression line should
be superimposed over an xyplot. NULL ~ FALSE. (y~x)
A NULL value indicates that no superposed line
should be added to the graph. If TRUE then a smooth of the data will
be superimposed.
A string with the name of any grouping variable (used as
the groups argument to panel.xyplot.
A logical value indicating whether text labels should be
used as plotting symbols (the variable used for these symbols
indicated by the idlab xpose data variable).
The aspect ratio of the display (see xyplot).
A string or a vector of strings with the name(s) of the conditioning variables.
Logical value. If TRUE, and by is not NULL,
the variable specified by by is taken as categorical.
Logical value.
A string with the name of a variable to be used to
reorder any factor conditioning variables (by). The variable
is used in a call to the reorder.factor function.
The name of the function to be used when reordering a
factor conditioning variable (see argument ordby)
The number of shingles ("parts") a continuous conditioning variable should be divided into.
The amount of overlap between adjacent shingles (see
argument shingnum)
The name of the function to be used as the strip argument
to the xyplot.
A string giving the plot title or NULL if none.
A string giving the label for the x-axis. NULL if none.
A string giving the label for the y-axis. NULL if none.
A string giving the subset expression to be applied to
the data before plotting. See xsubset.
A list to be used for the scales argument in
xyplot.
Should we create mirror plots from simulation data?
Value can be FALSE, TRUE or 1 for one mirror
plot, or 3 for three mirror plots.
The maximum number of plots per page that can be created with the mirror plots.
The aspect ratio of the plots used for mirror functionality.
An integer between 1 and object@Nsim
(seexpose.data-class) specifying which of the
simulated data sets to extract from SData.
Should we pass the list of plots created with
mirror or should we print them directly. Values can be
TRUE/FALSE.
The size of the x-axis label.
The size of the y-axis label.
The size of the title.
an internal mirror argument used in
create.mirror. Checks if the
strip argument from qqmath has been used.
Other arguments passed to xpose.panel.default.
Returns a scatterplot matrix graph object.
If ids is TRUE, text labels are added to the plotting
symbols. The labels are taken from the idlab xpose data
variable. The way the text labels are plotted is governed by the
idsmode argument (passed down to the panel
function). idsmode=NULL (the default) means that only extreme
data points are labelled while a non-NULL value adds labels to
all data points (the default in Xpose 3). xpose.panel.default
identifies extreme data points by fitting a loess smooth (y~x)
and looking at the residuals from that fit. Points that are associated
with the highest/lowest residuals are labelled. "High" and "low" are
judged by the panel function parameter idsext, which gives the
fraction of the total number of data points that are to be judged
extreme in the "up" and "down" direction. The default value for
idsext is 0.05 (see link{xpose.prefs-class}). There is
also a possibility to label only the high or low extreme points. This
is done through the idsdir argument to
xpose.panel.default. A value of "both" (the default) means that
both high and low extreme points are labelled while "up" and "down"
labels the high and low extreme points respectively.
More graphical parameters may be passed to
xpose.panel.splom.
for example, if you want to adjust the size of the varnames and
axis tick labels you can use the parameters
varname.cex=0.5 and axis.text.cex=0.5.
