F_1_panel.xyplot {lattice} | R Documentation |
This is the default panel function for xyplot
. Also see
panel.superpose
. The default panel functions for
splom
and qq
are essentially the same function.
panel.xyplot(x, y, type = "p", groups = NULL, pch, col, col.line, col.symbol, font, fontfamily, fontface, lty, cex, fill, lwd, horizontal = FALSE, ..., grid = FALSE, abline = NULL, jitter.x = FALSE, jitter.y = FALSE, factor = 0.5, amount = NULL, identifier = "xyplot") panel.splom(..., identifier = "splom") panel.qq(..., identifier = "qq")

variables to be plotted in the scatterplot |
type |
character vector consisting of one or more of the
following: "p" , "l" , "h" , "b" ,
"o" , "s" , "S" , "r" , "a" ,
"g" , "smooth" . If type has more than one element, an
attempt is made to combine the effect of each of the components.
The behaviour if any of the first six are included in
Type

groups |
an optional grouping variable. If present,
panel.superpose will be used instead to display each
subgroup |
col, col.line, col.symbol |
default colours are obtained from plot.symbol and
plot.line using trellis.par.get .
|
font, fontface, fontfamily |
font used when pch is a character
|
pch, lty, cex, lwd, fill |
other graphical parameters. fill serves the purpose of
bg in points for certain values of pch
|
horizontal |
A logical flag controlling the orientation for certain
type 's, e.g., "h" , "s" , ans "S" .
|
... |
Extra arguments, if any, for panel.xyplot . In most cases
panel.xyplot ignores these. For types "r" and "smooth",
these are passed on to panel.lmline and panel.loess
respectively.
|
grid |
A logical flag, character string, or list specifying whether and how
a background grid should be drawn. This provides the same
functionality as type="g" , but is the preferred alternative
as the effect type="g" is conceptually different from that of
other type values (which are all data-dependent). Using the
grid argument also allows more flexibility.
Most generally,
grid = FALSE .
|
abline |
A numeric vector or list, specifying arguments arguments for
panel.abline , which is called with those arguments.
If specified as a (possibly named) numeric vector, abline is
coerced to a list. This allows arguments of the form abline =
c(0, 1) , which adds the diagonal line, or abline = c(h = 0, v
= 0) , which adds the x- and y-axes to the plot. Use the list form
for finer control; e.g., abline = list(h = 0, v = 0, col =
"grey") .
For more flexibility, use |
jitter.x, jitter.y |
logical, whether the data should be jittered before being plotted. |
factor, amount |
controls amount of jittering. |
identifier |
A character string that is prepended to the names of grobs that are created by this panel function. |
Creates scatterplot of x
and y
, with various
modifications possible via the type argument. panel.qq
draws a
45 degree line before calling panel.xyplot
.
Note that most of the arguments controlling the display can be
supplied directly to the high-level (e.g. xyplot
) call.
