In lattice: Trellis Graphics for R

Useful panel function with qqmath

Description

Useful panel function with qqmath. Draws a line passing through the points (usually) determined by the .25 and .75 quantiles of the sample and the theoretical distribution.

Usage

panel.qqmathline(x, y = x,
                 distribution = qnorm,
                 probs = c(0.25, 0.75),
                 qtype = 7,
                 groups = NULL, 
                 ...,
                 identifier = "qqmathline")

Arguments

x	The original sample, possibly reduced to a fewer number of quantiles, as determined by the f.value argument to qqmath
y	an alias for x for backwards compatibility
distribution	quantile function for reference theoretical distribution.
probs	numeric vector of length two, representing probabilities. Corresponding quantile pairs define the line drawn.
qtype	the type of quantile computation used in quantile
groups	optional grouping variable. If non-null, a line will be drawn for each group.
...	other arguments.
identifier	A character string that is prepended to the names of grobs that are created by this panel function.
