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.
