fitline = FALSE, slope = NULL, intercept = NULL, overlines = FALSE,
groups = NULL, ..., col.line = trellis.par.get("add.line")$col,
pch = 16, lwd = 2, lty = 2)
Arguments
x, data, panel, xqqmath, ...
qqmathline
a logical: should line be displayed passing through first and third quartiles?
idline
a logical; should the line y=x be added to the plot?
fitline
a logical; should a ftted line be added to plot? Such a line will use slope
and intercept
if provided, else the standard deviation and mean of the data.
slope
slope for added math line
intercept
intercept for added math line
overlines
a logical: should lines be on top of qq plot?
groups, pch, lwd, lty
as in lattice plots
col.line
color to use for added lines
