With R-2.8 installed under Windows XP, I installed (D)COM, specifically
using RSrv250.exe. Something's wrong in the configuration.
When I try "Server 01- Basic Test," I get a pop-up "StatConnector Test"
window. If I click the Start R button, I see:
Loading StatConnector Server... Done
Initializing R...Function call failed
Code: -2147221485
Text: installation problem: unable to load connector
and I get a separate "Test1" pop-up saying "Method '~' of object '~' failed.
If instead, I try "Excel 01 - R Server Connection demo", immediately I
get RExcel.xla opened in the Microsoft Visual Basic debugger with a
pop-up window "Microsoft Visual Basic" saying, "Compile error: Can't
find project or library." The debugger has stopped at the word "Left"
in the line
ExcelVersionMajor = CInt(Left(Application.Version, pos - 1))
of the function ExcelVersionMajor().
I stop the debugger. Excel 2003 is still open. I close it and then
reopen it in order to deactivate the RExcel add-in. When I use Tools >
Add-ins and uncheck RExcel, I get a "Microsoft Visual Basic" pop-up
window saying "Can't find project or library." I quit that window and
get a "VBAProject Password" window, which I cancel.
Next, I reactivate RExcel add-in and now I get a new pop-up window,
"References - RExcelVBAlib" and I see the item:
MISSING RCOM 1.0 Type Library
with the message that this is should be in Location:
C:\PROGRA~2\R\R-24~1.1\library\rcom\libs\rcom_srv.tlb
But I do not have R installed there. Here's my setup:
My system PATH includes
D:\Stat\R\R2.8\bin
(which is correct), and the file rcom_srv.tlb from rcom is in:
D:\Stat\R\myRlib\rcom\libs
In D:\Stat\R\R-2.8\bin, I have .Renviron, which includes:
R_USER=e:/Documents/R
R_LIBS=d:/Stat/R/myRlib
And that target of R_USER is where my .Rprofile is kept. It includes as
last line:
library(rcom)
and has no trouble, apparently, loading that library when I just start R
directly.
I also have the Windows system variable R_HOME set to D:\Stat\R\R-2.8.
I suspect part of the problem may arise from the file .Renviron that is
installed by RSrv250.exe into D:\Stat\R\(D)COM Server\xls. It contains
the single line: library(rcom)
BUT... where is something picking up the spurious location
"C:\PROGRA~2\R\R-24~1.1\library\rcom\libs\rcom_srv.tlb" for
rcom_srv.tlb, and how do I fix this.
