[R] lattice splom: how to adjust space between tick marks and tick labels?

[Marius Hofert]

Dear expeRts,

how can I decrease the space between the tick marks and the corresponding labels in an splom?
See here:

library(lattice)
U <- matrix(runif(4000), ncol = 8)
splom(U, axis.text.cex = 0.2) # => space between the [small] tick labels and tick marks is/seems to be too large

I checked ?panel.pairs but could not find an option for that.

Cheers,

Marius
