F_1_panel.xyplot | 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, ...,
smooth = NULL,
grid = lattice.getOption("default.args")$grid,
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 controlling how The behaviour if any of the first five are included in Type The remaining values of Type See |
groups |
an optional grouping variable. If present,
|
col , col.line , col.symbol |
default colours are obtained from |

horizontal |
A logical flag controlling the orientation for certain

Extra arguments, if any, for |
smooth |
If specificied, indicates the type of smooth to be
added. Can be a character vector containing one or more values from
Normally, smoothing is performed with the |
grid |
A logical flag, character string, or list specifying whether and how
a background grid should be drawn. This provides the same
functionality as Most generally,
No grid is drawn if |
abline |
A numeric vector or more generally a list containing arguments that
are used to call 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.
