prepanel.functions: Useful Prepanel Function for Lattice

Description

These are predefined prepanel functions available in Lattice.

prepanel.lmline(x, y, ...)
prepanel.loess(x, y, ...)
prepanel.qqmathline(y, distribution, f.value = ppoints, ...)

x, y

x and y values.

distribution

quantile function for theoretical distribution

f.value

as used in qqmath

...

other arguments

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. There are also several undocumented prepanel functions that serve as the default for high level functions, e.g., prepanel.default.xyplot

prepanel.loess(x, y, span, degree, family, evaluation, lwd, lty, col, ...)
