Hello,
I am basically using a script that is designed to first create an
rgl 3d scatter plot followed by a barplot on the same data. After
this is done, the program is to first save the barplot as a .tiff
file then to save the rgl 3d graph as a .png file. Once this is
done, it is to repeat this 3d plot and barplot combo with saving 49
more times. The plotting script excerpt will be posted at the end of
this email, and yes, the "setwd(...)" command is used correctly in
the script just censored here. I have basically had problems with
this script in three different ways.
In Windows Vista Home Premium, all 50 graph pairs are generated and
the barplots are saved just fine as .tiff files, but the rgl .png
files are saved as a giant black square instead of a graph. The
other problem with Vista is that when I save the workspace image, it
does not reload when I intentionally load the image. There are no
error messages, all console evidence shows that the image loaded
just fine but nothing shows up. I have also tried this on Mac OSX
Snow Leopard (10.6). The machine stops after the first barplot is
generated and states that there is an error in the 'savePlot'
command and that X11(type ="*cairo") is not understood or something
to the effect [I do not have the Mac with me at the time]. The
script just stops after this error, so I do not know if the rgl or
the .Rimage files save properly yet.
Thank you for your time,

# PLOT
open3d()

dev.new()

setwd(...) # why?
plot3d(SN_PCA_All, col=rainbow(nrow(SN_PCA_All)))
Error in plot3d(SN_PCA_All, col = rainbow(nrow(SN_PCA_All))) :
object 'SN_PCA_All' not found
decorate3d(main ="SN_All_Ca")
barplot(SN_Scree_All_Percent[,1], main = "SN_All_Ca")
savePlot(filename = "01 +S+Na_AllCa_Scree", type ="tiff")
Wouldn't you want to close the first and second devices before opening
a third one?
rgl.viewpoint(180,0)
Did your read the part of the help page that says:
"We recommend that you avoid mixing rgl.* and *3d calls."
rgl.snapshot("01 +S+Na_AllCa_PCA.png", fmt="png", top=TRUE )
I get the idea that you need to read more about graphics devices in R.
You have multiple devices open at once and it is not clear where the
output would be going.

Since you are posting in HTML, you also have may not have read the
part of the posting guide where is suggests that a working example
should be included. I could be wrong and that SN_PCA_All dataset could
be part of some package, in which case it would be good manners to
include the name of that package.
I am willing to give a shot at seeing if the 32 bit version of R on
Leopard would run a complete example, and do some experimentation, but
I am not willing to guess at what your data looks like. (The savePlot
documentation on my Mac suggests that you should have opened up an X11
cairo device with type="cairo" rather than the (default) quartz device
that dev.new() would typically open.)
?savePlot
You should probably explain why you are using savePlot, since, on the
Mac anyway, there are already tiff and png devices that may not get
hung up with potential X11 confusion.
