[R] Installing R-Excel Interface - Help requested (long)
Dear All,
I have attempted to install the R-Excel Interface with poor results.
The version of R is 1.6.1, the version of R-Excel is 1.0, the version of COM
is 0.99. All of these were downloaded Monday, 6 January 2003. R (version
1.6.1) is installed on the machine and appears to run correctly on its own.
The computer is a Compaq Pentium 4 machine with 128 meg of RAM running
Windows 2000 and Excel 2000 (9.0.4402 SR-1).
After installing DCOM and the R-Excel Interface as per the instructions (I
believe), I get one of two errors upon attempting to invoke the R-Excel
interface within Excel.
1. If the Rserver box is ticked within Tools / Addins upon
launching Excel, I get "invalid picture error (error 481)". If I
click OK
within the error dialog box it takes me to
RserverVBAlib (Rserver.xla)
Modules
Rinterface
and highlights the statement:
Dim My_R As StatConnector
2. If I open Excel without the Rserver box ticked within Tools
/ Addins, Excel opens normally, but then when I tick the R Interface box
within Toos / Addins I get "error in loading DLL (error 48)".
The vbtest.exe utility seemed to run correctly after installing DCOM.
Details of all the error messages and the vbtest output can be found below.
I would be most grateful if someone can show me how to make this work
properly.
Thank you for your help.
Best regards,
Herb

If the Rserver box is ticked within Tools / Addins upon launching Excel, I
get "invalid picture error (error 481)".
Invalid picture (Error 481)
An invalid graphics format was assigned to the Picture property. This error
has the following cause and solution:
* You tried to assign a graphics format other than a bitmap,
icon, or Windows metafile to the Picture property of a form or control.
Ensure that the file you are trying to load into the Picture
property is a valid graphics file supported by Visual Basic.
If I click OK within the error dialog box it takes me to
RserverVBAlib (Rserver.xla)
Modules
Rinterface
and highlights the statement:
Dim My_R As StatConnector
The entire beginning of Rinterface is below.
Option Base 1
Public Const RExcelVersion = "Version 0.73"
Dim myitem As Object
Dim FlatMenus As Boolean
Dim My_R As StatConnector
If I open Excel without the Rserver box ticked within Tools /
Addins, Excel opens normally, but then when I tick the R Interface box
within Toos / Addins I get "error in loading DLL (error 48)".
The entire error message is below.
Error in loading DLL (Error 48)
A dynamic link library (DLL) <JavaScript:hhobj_3.Click()> is a library
specified in the Lib clause of a Declare statement. This error has the
following causes and solutions:
* The file isn't DLL-executable.
If the file is a source-text file, it must be compiled and
linked to DLL executable form.
* The file isn't a Microsoft Windows DLL.
Obtain the Microsoft Windows DLL equivalent of the file.
* The file is an early Microsoft Windows DLL that is
incompatible with Microsoft Windows protect mode.
Obtain an updated version of the DLL.
* The DLL references another DLL that isn't present.
Obtain the referenced DLL and make it available to the other
DLL.
* The DLL or one of the referenced DLLs isn't in a directory
specified by your path.
Move the DLL to a referenced directory or place its current
directory on the path.
For additional information, select the item in question and press F1 (in
Windows) or HELP (on the Macintosh).
Selected sections of the output of the vbatest utility are below.
