F_1_panel.pairs {lattice} | R Documentation |
This is the default superpanel function for splom
.
panel.pairs(z, panel = lattice.getOption("panel.splom"), lower.panel = panel, upper.panel = panel, diag.panel = "diag.panel.splom", as.matrix = FALSE, groups = NULL, panel.subscripts, subscripts, pscales = 5, prepanel.limits = scale.limits, varnames = colnames(z), varname.col, varname.cex, varname.font, varname.fontfamily, varname.fontface, axis.text.col, axis.text.cex, axis.text.font, axis.text.fontfamily, axis.text.fontface, axis.text.lineheight, axis.line.col, axis.line.lty, axis.line.lwd, axis.line.alpha, axis.line.tck, ...) diag.panel.splom(x = NULL, varname = NULL, limits, at = NULL, labels = NULL, draw = TRUE, tick.number = 5, varname.col, varname.cex, varname.lineheight, varname.font, varname.fontfamily, varname.fontface, axis.text.col, axis.text.alpha, axis.text.cex, axis.text.font, axis.text.fontfamily, axis.text.fontface, axis.text.lineheight, axis.line.col, axis.line.alpha, axis.line.lty, axis.line.lwd, axis.line.tck, ...)
z |
The data frame used for the plot. |
panel, lower.panel, upper.panel |
The panel function used to display each pair of variables. If
specified, lower.panel and upper.panel are used for
panels below and above the diagonal respectively.
In addition to extra arguments not recognized by |
diag.panel |
The panel function used for the diagonals. See arguments to
diag.panel.splom to know what arguments this function is
passed when called.
|
as.matrix |
logical. If TRUE , the layout of the panels will have origin
on the top left instead of bottom left (similar to
pairs ). This is in essence the same functionality as provided
by as.table for the panel layout
|
groups |
Grouping variable, if any |
panel.subscripts |
logical specifying whether the panel function accepts an argument
named subscripts .
|
subscripts |
The indices of the rows of z that are to be
displayed in this (super)panel.
|
pscales |
Controls axis labels, passed down from splom .
If pscales is a single number, it indicates the approximate
number of equally-spaced ticks that should appear on each axis. If
pscales is a list, it should have one component for each
column in z , each of which itself a list with the following
valid components:
These are specifications on a per-variable basis, and used on all
four sides in the diagonal cells used for labelling. Factor
variables are labelled with the factor names. Use |
prepanel.limits |
A function to calculate suitable axis limits given a single argument
x containing a data vector. The return value of the function
should be similar to the xlim or ylim argument
documented in xyplot ; that is, it should be a numeric
or DateTime vector of length 2 defining a range, or a character
vector representing levels of a factor.
Most high-level lattice plots (such as |
x |
data vector corresponding to that row / column (which will be the same for diagonal ‘panels’). |
varname |
(scalar) character string or expression that is to be written centred within the panel |
limits |
numeric of length 2, or, vector of characters, specifying the scale for that panel (used to calculate tick locations when missing) |
at |
locations of tick marks |
labels |
optional labels for tick marks |
draw |
A logical flag specifying whether to draw the tick marks and labels.
If FALSE , variable names are shown but axis annotation is
omitted.
|
tick.number |
A Numeric scalar giving the suggested number of tick marks. |
varnames |
A character or expression vector or giving names to be used for the
variables in x . By default, the column names of x .
|
varname.col |
Color for the variable name in each diagonal
panel. See gpar for details on this and the
other graphical parameters listed below. |
varname.cex |
Size multiplier for the variable name in each diagonal panel. |
varname.lineheight |
Line height for the variable name in each diagonal panel. |
varname.font, varname.fontfamily, varname.fontface |
Font specification for the variable name in each diagonal panel. |
axis.text.col |
Color for axis label text. |
axis.text.cex |
Size multiplier for axis label text. |
axis.text.font, axis.text.fontfamily, axis.text.fontface |
Font specification for axis label text. |
axis.text.lineheight |
Line height for axis label text. |
axis.text.alpha |
Alpha-transparency for axis label text. |
axis.line.col |
Color for the axes. |
axis.line.lty |
Line type for the axes. |
axis.line.lwd |
Line width for the axes. |
axis.line.alpha |
Alpha-transparency for the axes. |
axis.line.tck |
A numeric multiplier for the length of tick marks in diagonal panels. |
... |
Further arguments, passed on to panel , lower.panel ,
upper.panel , and diag.panel from panel.pairs .
Currently ignored by diag.panel.splom .
|
panel.pairs
is the function that is actually used as the panel
function in a "trellis"
object produced by splom
.
