Hi,
At the moment I see what went wrong, with no idea how to correct it, or
what causes this behaviour.
The .First.lib function of this package contains the following lines
file <- system.file(path, package = pkg, lib.loc = lib)[1]
.Tcl(paste("load", file, "Rplot"))
where the values of the variables at moment of the call are
path="libs/tkplot.dll"
pkg="tkrplot"
lib=NULL
So the problem is that if you call the
system.file
function in background server you obtain the full path name with spaces
in it (Program Files) while in the forground server you obtain a short
path name as Progra~1/ etc.
In the next line the .Tcl command therefore sees three arguments in case
of the background server, and this is the problem.
sytem.file uses the value of .Library variable. This is set to the
long path format in background server and short path format in
foreground server.
A workaround is to set this variable by hand to short path name of the
library directory using
assignInNamespace(".Library",<short path name to library dir>,ns="base")

Hi RExcel users,
I am exploring the package tkrplot. This allows you to build interactive plots using tctlk.
>From Excel I am running the following source using "Rinterface.RunRFile":
library(tcltk)
library(tkrplot)
tt <- tktoplevel()
bb<-1
img <-tkrplot(tt, function() plot(1:20,(1:20)^bb))
f<-function(...) {
b <- as.numeric(tclvalue("bb"))
if (b != bb) {
bb <<- b
tkrreplot(img)
}
}
s <- tkscale(tt, command=f, from=0.05, to=2.00, variable="bb",
showvalue=FALSE, resolution=0.05, orient="horiz")
tkpack(img,s)
My example works fine when I am using a foreground server config in RExcel.
However, as soon as I switch to a background server config I get an error message (using the Debug R option in RExcel) saying
Error in library(tkrplot) : .First.lib failed for 'tkrplot'
i.e. that loading of the library(tkrplot) has failed.
Any ideas why this should happen or how to fix it?
I am using R version 2.6.1
R(D)Com server is: RSrv250_pl1.exe

May I suggest you try a newer version of R. The current verion is
2.6.1 which can be found here http://cran.r-project.org/bin/windows/base/R-2.6.1-win32.exe
Also there is a newer version of R(D)Com which can be found here:
http://rcom.univie.ac.at/download/current/RSrv250_pl1.exe
I have no direct experience with Excel 2007 (yet) but I will need to
test R(D)Com on Excel 2007 and Vista in the very near future.
Therefore, I would be very interested to hear about your progress.
Regards
Wayne

Subject: [Rcom-l] RSrv200 and Excel 2007
Hello,
I installed R-2.4.1-win32.exe successfully.
Then I installed RSrv200.exe and I got an error "RExcel Addin … was
not found". (Unfortunately I don't have the full message at the
moment.)
I had selected "Excel Add-In" component during the installation.
I have Excel 2007 installed.
Which version of Excel does RSrv200 work with?
Which version of R(D)COM do I need to get it working with Excel 2007?
Thanks,
Baharak
