plot3d.formula

Methods for formulas

Description

These functions provide a simple formula-based interface to plot3d and persp3d.

Usage

## S3 method for class 'formula'
plot3d(x, data = NULL, xlab, ylab, zlab, ...)
## S3 method for class 'formula'
persp3d(x, data = NULL, xlab, ylab, zlab, ...)

Arguments

`x`	A formula like `z ~ x + y`.
`data`	An optional dataframe or list in which to find the components of the formula.
`xlab, ylab, zlab`	Optional axis labels to override the ones automatically obtained from the formula.
`...`	Additional arguments to pass to the default `plot3d` method, or the `persp3d` method for `"deldir"` objects.

Details

Only simple formulas (the ones handled by the xyz.coords function) are supported: a single variable on the left hand side (which will be plotted on the Z axis), and a sum of two variables on the right hand side (which will be the X and Y axis variables in the plot.)

Value

These functions are called for the side effect of drawing the plots. The plot3d method draws a scatterplot. The persp3d method draws a surface plot.

Return values are as given by the plot3d.default method or the persp3d.deldir methods.

Note

The persp3d method requires that the suggested package deldir is installed.
