I'm trying to create a 3D plot using wireframe with certain parts removed.  I would like to get rid of the part of the outer cube that crosses over the plot leaving the back two walls and the axes.  It would also be useful to put lines in the plot separate from the wireframe call.  I've looked through the documentation and have not been able to find such a request.  Here is my code attempting to rid the wireframe plot of some of the cube lines.
 
trellis.par.set('axis.line', list(col='transparent'))trellis.par.set('box.3d', list(col='transparent'))
wireframe(Data ~ Freqq*Time, scales=list(arrows=FALSE, cex=0.75, col='black', tck=1),  screen=list(z=-10, x=-70, y=0), xlim=c(0, max(Freqq)), zoom=0.85, col='darkgrey', aspect=c(1.75,.65), xlab=list(label='Frequency (Hz)'),  ylab='Time (Sec)', perspective=FALSE, zlab=list(label=expression(lb[f]), just=-1), par.box = list(col=c(1,1,NA,1,1,NA,1,1,1)))
I found that the par.box option controls multiple lines in the plot not just one at a time.  I have made some attempts at adding lines to the plot to put profile plots on the 'back walls', but don't know where to start.  Thank you in advance.
