You can specify some options in "par.box". Use col=NA to make the frame
transparent. See example below (which was modified from the help file).
See also the "scales" parameter if you want to remove the arrows as 
well.

    library(lattice)
    x <- seq(-pi, pi, len = 20)
    y <- seq(-pi, pi, len = 20)
    g <- expand.grid(x = x, y = y)
    g$z <- sin(sqrt(g$x^2 + g$y^2))
    wireframe(z ~ x * y, g, drape = TRUE,
              perspective = FALSE,
              aspect = c(3,1), colorkey = FALSE,
              par.box = list(col=NA))

Which doesn't work on device
trellis.device(windows)
but works well on, e.g.,
trellis.device(postscript)

Deepayan, since I don't have the time to check that right now: Is this
bug known? Is this a bug in R, grid or lattice?

Not sure, and I don't have access to R on Windows right now. This is 
probably a grid issue, try doing
grid.newpage()
grid.lines(gp = gpar(col = NA))

But I think col="transparent" would be a better choice than col=NA 
here. Does that work on windows() ?

No, thanks.

I'll take a closer look later ....

Sorry, I do not have the time to look really close, but a *long shot* is 
that we have discovered a windows-only bug related to the fixed PR#1881.
Perhaps a similar bug in lattice as it was in R-base?
