prepanel.functions: Useful Prepanel Function for Lattice
Description
These are predefined prepanel functions available in Lattice.Usage
prepanel.lmline(x, y, ...)
prepanel.loess(x, y, ...)
prepanel.qqmathline(y, distribution, f.value = ppoints, ...)
Arguments
x, y
x and y values, numeric or factor
distribution
quantile function for theoretical
distribution. This is automatically passed in when this is used as a
prepanel function in qqmath.
Value
- usually a list with components
xlim, ylim, dx, dy, the first
two being used to calculate panel axes limits, the last two for
banking computations. The form of these components are described under
xyplot. There are also several undocumented prepanel
functions that serve as the default for high level functions, e.g.,
prepanel.default.xyplot
synopsis
prepanel.loess(x, y, span, degree, family, evaluation, ...)
