panel.qqmathline {lattice} | R Documentation |
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.
panel.qqmathline(x, y = x, distribution = qnorm, p = c(0.25, 0.75), qtype = 7, groups = NULL, ...)
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. |
p |
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. |
