Hi there,
The tool to learn for this is the cast function using the reshape package.
In your example you have more then one value for RTL, which you should think
of how to account for.
But basically, here is a solution to what you asked for (assuming I
understood you correctly)
require(reshape)
is on the PATH, the DLLs can conflict.

Hi all,
The error I got was this:
Error in normalizePath(path) :
path[1]=C:\Program Files\R\library/gdata: The system cannot find the
file specified
(after some other packages updated fine)
For running:
update.packages(checkBuilt=TRUE, ask=FALSE)

Not answering your question,
But if you where to ask this regarding plots, the answer would be to use:

Hello Peter,
Thank you, and the R core team, for the new release.
I see that in R 2.11.0 there is now support for rendering of raster (bitmap)
images through rasterImage().
I am wondering - can this be used to create a texture/fill-pattern for
hist()/barplot() ?
(A request made several times
Ah.
Close to what David suggested...
Try:
?which.max

Good luck in your work,
The simple solution would be to run many non-paired wilcox on all the 20
questions (the way Dieter suggested).
In which case, make sure to adjust for multiple comparisons. Read about it,

If you have some questions you can merge (by a simple mean of
