prepanel.functions {lattice}  R Documentation 
These are predefined prepanel functions available in Lattice.
prepanel.lmline(x, y, ...) prepanel.loess(x, y, ...) prepanel.qqmathline(y, distribution, f.value = ppoints, p = c(0.25, 0.75), ...)
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 .

f.value 
as used in qqmath 
p 
numeric vector of length two, representing probabilities. Corresponding quantile pairs define the line used. 
... 
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
undocumented prepanel functions that serve as the default for high
level functions, e.g., prepanel.default.xyplot
