Panel function for qqmath
to reduce the number of points
plotted by sampling along the specified distribution. The usual method
for such sampling is to use the f.value
argument to
panel.qqmath
. However, this panel function differs in
two ways:
(1) a specified number of data points are retained (not
interpolated) on each tail of the distribution.
(2) the sampling is evenly spaced along the specified
distribution automatically (whereas f.value = ppoints(100)
is
evenly spaced along the uniform distribution only).
This function is deprecated as of lattice 0.18-4 (available for
R 2.11.0). Use the tails.n
argument of
panel.qqmath
instead.
panel.qqmath.tails(x, f.value = NULL, distribution = qnorm, groups = NULL, ..., approx.n = 100, tails.n = 10)
x, f.value, distribution, groups |

further arguments passed on to |
approx.n |
number of points to use in approximating the distribution. Points will be equally spaced in the distribution space. |
tails.n |
number of points to retain (untouched) at both the high and low tails. |

panel.qqmath
which should be used instead (as of lattice 0.18-4).
