Good morning,

I really enjoy some of the recent convenience functions in lattice_0.20-15 and latticeExtra_0.6-24. I am wondering if there is a way to use multiple functions in the same call? Specifically, I would like to be able to use yscale.components.log10ticks (to get the major tick marks at powers of 10 and minor tick marks in between) and also label the major tick marks smartly using superscripts for the power. Something along the lines of this:

##Pseudocode, does not work
xyplot((1:200)/20 ~ (1:200)/20, type = c("p", "g"),
       scales = list(x = list(log = 2), y = list(log = 10)),
       xscale.components = xscale.components.fractions,
       yscale.components = list(yscale.components.log10ticks,
                                yscale.components.logpower))

or this:
##Does not work
xyplot((1:200)/20 ~ (1:200)/20, type = c("p", "g"),
       scales = list(x = list(log = 2), y = list(log = 10)),
       xscale.components = xscale.components.fractions,
       yscale.components = function(...){
         yscale.components.log10ticks
         yscale.components.logpower}
       )

Thanks!
Sean
