| tmd {lattice} | R Documentation |
Create Tukey Mean-Difference Plots from a trellis object returned by
xyplot (and perhaps qq as well in future)
tmd(object, xlab = "mean", ylab = "difference", ...)
object |
An object of class ``trellis''. Currently only the
value returned by xyplot gives sensible results. |
xlab |
x label |
ylab |
y label |

other arguments, see trellis.args |
The Tukey Mean-difference plot is produced by modifying the (x,y)
values of each panel as follows: the new coordinates are given by
x=(x+y)/2, y=y-x.
Most arguments given to produce object are transmitted to tmd,
with the notable exceptions of aspect and scales. (This
behaviour is different from S-Plus.)
