hi all
I have another question reated to the dotchart: is it possible by
means of
par() to set a logaritmic scale?
If yes, how ? and if not, any alternative solution?
Looking at the dotchart code it appears to me that the log parameter
to plot.window is hard-coded at "", i.e both scales are linear.
Testing with the xlog parameter to par does fail. You can always
define a new dochart2 on the basis of that code.
Another alternative would be lattice (a simple mod to one of its
examples shows it "works"):
dotplot(variety ~ yield | site, data = barley, groups = year,
key = simpleKey(levels(barley$year), space = "right"),
scales=list(x=list(log=TRUE)),
xlab = "Barley Yield (bushels/acre) ",
aspect=0.5, layout = c(1,6), ylab=NULL)
