prepanel.functions {lattice}  R Documentation 
These are predefined prepanel functions available in Lattice.
prepanel.lmline(x, y, ...) prepanel.loess(x, y, span, degree, family, evaluation, ...) prepanel.qqmathline(x, y = x, distribution = qnorm, p = c(0.25, 0.75), qtype = 7, groups, subscripts, ...)
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 .

qtype 
type of quantile 
p 
numeric vector of length two, representing probabilities. If used
with aspect="xy" , the aspect ratio will be chosen to make the
line passing through the corresponding quantile pairs as close to 45
degrees as possible.

span, degree, family, evaluation 
arguments controlling the
underlying loess smooth 
groups, subscripts 
See xyplot . Whenever
appropriate, calculations are done separately for each group and
then combined. 
... 
other arguments 
usually a list with components xlim
, ylim
, dx
and
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
prepanel functions that serve as the default for high level functions,
