hexplom: Hexbin Plot Matrices
hexplom draws Conditional Hexbin Plot Matrices. It is similar
splom, expect that the default display is different.
Specifically, the default display is created using
panel.hexplom, which is an alias for
hexplom(x, data, ...)
## S3 method for class 'formula'
hexplom(x, data = NULL, ...)
## S3 method for class 'data.frame'
hexplom(x, data = NULL, ..., groups = NULL,
subset = TRUE)
## S3 method for class 'matrix'
hexplom(x, data = NULL, ..., groups = NULL, subset = TRUE)
The object on which method dispatch is carried out.
"formula" method, a formula describing the structure
of the plot, which should be of the form
~ x | g1 * g2 *
x is a data frame or matrix. Each of
g2, ... must be either factors or shingles. The conditioning
g1, g2, ... may be omitted.
matrix methods, a data frame or
matrix as appropriate.
formula method, an optional data frame in which
variables in the formula (as well as
subset, if any) are to be evaluated. By default, the
environment where the function was called from is used.
groups, subset, ...
non-standard evaluation of
applies in the
formula method. Apart from arguments that
splom (many of which are only documented in
xyplot), additional arguments meant for
panel.hexplom (which is an alias for
panel.hexbinplot) may also be supplied. Such
arguments may include ones that control details of the hexbin
calculations, documented in
An object of class
update method can be used to
update components of the object and the
print method (usually called by
default) will plot it on an appropriate plotting device.

## Simple hexplom
## With colors and conditioning
hexplom(~NHANES[,9:13] | Sex, data = NHANES,
xbins = 15, colramp = magent)
## With custom panel function
hexplom(NHANES[,9:13], xbins = 20,colramp = BTY,
upper.panel = panel.hexboxplot)
