The Lattice auto.key argument has a bug in R.12.2.
R version 2.12.2 (2011-02-25)
Platform: i386-pc-mingw32/i386 (32-bit)
....
other attached packages:
[1] lattice_0.19-17
loaded via a namespace (and not attached):
[1] grid_2.12.2
If I set up my plot parameters as
require(lattice)
superpose.line.settings <- trellis.par.get("superpose.line")
str(superpose.line.settings)
superpose.line.settings$col <- 1
superpose.line.settings$lty <- c(1,2,5) *****
superpose.line.settings$lwd <- 2
trellis.par.set("superpose.line",superpose.line.settings)
and then set up my key list as
my.key <- list(space="top", points=FALSE, lines=TRUE, columns=3)
and then run xyplot with the argument auto.key=my.key,
I do NOT get the proper legend at the top of the plot.
Instead of the lines in the legend having the characteristics of
lty=c(1,2,5), they have the characteristics of lwd=c(1,2,5).
The auto.key argument works fine in R.12.1
R version 2.12.1 (2010-12-16)
Platform: i386-pc-mingw32/i386 (32-bit)
