Thanks Peter.

This is true, but consider this continuation of my example (which is
probably what I should have written originally):


my.opts <- list(default.args = list(
                      as.table = TRUE,
                                   between = list(x = 0.2, y = 0.2),
scales = list(alternating = 1, tck = c(1, 0), col =
'black') # Illustrative, doesn't do anything
               ))


oldopts <- lattice.options(my.opts)

useOuterStrips(xyplot(
                     resp ~ time | subject * var,
                     data = temp
                     ))

lattice.options(oldopts)


If the scales option worked like as.table, aspect, etc, then I wouldn't need to use a default.scales call per xyplot. Just trying to remove some typing
from each call that I make.

You might want to look at the modifyList {utils} function.

Searching for a specific example produces (among others):

New feature not needed. You'll notice that the 'Details'
section of ?xyplot says, regarding lattice.options:

  Default values can be set in this manner for the following
  arguments: as.table, aspect, between, page, main, sub,
  par.strip.text, layout, skip and strip.

No mention of 'scales'. But xyplot has an argument
'default.scales' which you can set globally:

 def.scal <- list(alternating = 1, tck = c(1, 0))

and then add this

 default.scales = def.scal

to the arguments in your xyplot call.
