Dear R experts,
it would be very kind if you could help me with two wireplot problems.
First, when I make a wireplot and transform it into an .eps using the postscript function the eps-file leaves always a lot of space below the plot, as if it would leave space for a legend or something like that.
How can i get the plot into the bottom corner without the space below? The space is not there when I just display the plot in R on my screen (I use R.2.3.1 on Windows XP). in general, how can I get the margins on all sides as small as possible since I wnat to include the eps into a report and do not need the space around.
The following code has the space on the eps:
library(lattice)
plot.vol <- wireframe(volcano, aspect = 1, scales=list(arrows=F) ,zlab=list("Z-axis",rot=90))
postscript("example_plot.eps", width = 14.0/2.54, height = 19.0/2.54,
horizontal = FALSE, onefile = FALSE,paper="special")
trellis.par.set("axis.line",list(alpha=1,col=1,lty=0,lwd=1))
print(plot.vol)
dev.off()
Secondly, is it possible to add to the wireplot a further z-axis. I found only how to choose at which veritcal line I want the tickmarks and label, but is it also possible to have it at two vertical lines?
Thank you very much for your help!
Klaus

Dear Deepayan,

sorry for not being clear - but my problem has nothing to do with the aspect. If I create the eps the following way

library(lattice)
plot.vol<- wireframe(volcano,
aspect = c(1,1.5), scales=list(arrows=F),zlab=list("Z-axis",rot=90))

postscript("example_plot_3.eps", width = 14.0/2.54, height = 19.0/2.54,
horizontal = FALSE, onefile = FALSE,paper="special")
trellis.par.set("axis.line",list(alpha=1,col=1,lty=1,lwd=1))
print(plot.vol)
dev.off()

The plot is still not in the left bottom corner of the file. There is a lot of space below the outer box line. If I include this eps in latex it will also include this space and if I put for example the figure caption below it I have this huge gap between actual graph and caption.

And for comparison, if I create with xyplot an eps like

postscript("example_plot_4.eps", width = 14.0/2.54, height = 19.0/2.54,
horizontal = FALSE, onefile = FALSE,paper="special")

Depth <- equal.count(quakes$depth, number=8, overlap=.1)
plot.depth<-xyplot(lat ~ long | Depth, data = quakes)
update(trellis.last.object(),
strip = strip.custom(strip.names = TRUE, strip.levels = TRUE),
par.strip.text = list(cex = 0.75),
aspect = "iso")

print(plot.depth)
dev.off()

the figure is really in the left bottom corner and included in latex has not that gap between caption and actual figure.

I hope this describes my problem better.

Dear Deepayan,

thanks for your reply, the change of the aspect does however not solve
my problem with the space below the graph on the .eps
I attached the .eps (still with the old aspect) so that it is maybe
clearer what my
problem is.

No, it's not clearer; this is basically the same EPS that I got, so it
gives me no new information. What do you get with the new aspect? If
it's not what you want, you'll have to explain what you want more
clearly. Also, don't make the panel borders transparent, as it makes
it difficult to understand what's going on.

Deepayan

Any other suggestions?

it would be very kind if you could help me with two wireplot

all
sides as small as possible since I wnat to include the eps into a

Perhaps you want something like

aspect = c(1, 1.5)

instead.

postscript("example_plot.eps", width = 14.0/2.54, height =
19.0/2.54,
horizontal = FALSE, onefile = FALSE,paper="special")

trellis.par.set("axis.line",list(alpha=1,col=1,lty=0,lwd=1))

print(plot.vol)

dev.off()

Secondly, is it possible to add to the wireplot a further z-axis. I
found only how to choose at which veritcal line I want the tickmarks
and label,
but is it also possible to have it at two vertical lines?

No (but it shouldn't be too hard to add that feature; I'll have to
check).

There is some ambiguity here. The "aspect" arg to wireframe controls
the 3D aspect ratio. You want to control the 2D aspect ratio in the
displayed plot. It is stored in the aspect.ratio member of the
resulting object, and can be changed using

plot.vol$aspect.ratio <- 1.5

for example. You shouldn't really be fiddling around inside the object
like that, but I don't know how to avoid it in this case.

update(plot.vol, aspect = "fill")

seems to work, but I don't know if that should be considered a bug or
a feature.

I wonder what S-PLUS does (I no longer have access to a copy).
