Re: [Rcom-l] status RExcel, rcom, rscproxy, R2.8.0: confused still
Did you do an uninstall of the previous version of the (D)COM server? Your problem should not have happened if you had uninstalled. Were your servers configured as typed or as untyped? RExcelInstaller now installs RExcel in Program Files\RExcel One of the reasons is that it can even be used without R on the same machine, and putting it in a subdirectory of R_HOME would not make sense in that scenario. Murray Eisenberg wrote: I had downloaded (D)COM server 3.0 beta and installed it several days ago. But I just discovered why, even with that, why things were not working: It was the path to (D)COM! I had to execute the RExcel Set R Server Configure R server(s) command and enter the path to (D)Com there. I don't think I had seen anywhere that by default (D)COM was supposed to be at ..\(D)COM Server\ relative to RExcel.xla. I had installed (D)COM to one subdirectory of my main R directory (of which R-2.8.0 is a subdirectory, too) and RExcel to another subdirectory of that directory. I thought that was a sensible layout where I could neatly keep the two distributions, (D)COM and RExcel, separate from one another. I guess I had not encountered this before because, as I recall, RExcel used to be bundled in with the (D)COM server's installer.

Thanks for that information; I sure hope this cures the troubles.
Question: Off-topic, but intimately related...
Rprofile.site, in the R 2.8.0 etc directory, includes the lines:
library(utils)
if (.Platform$GUI %in% c(Rgui,Rterm)){
if(!(rcom %in% installed.packages()[, Package])){
install.packages(rcom, dep = T);
require(rcom);
dummy-comRegisterRegistry()} else {
require(rcom)}}
I'm not sure whether they were already there in the version of
Rprofile.site that came with the 2.8.0 distribution or whether I put
them there because I had them there in for an earlier version of R.
These lines are put there by the RExcelInstaller.
But obviously they block doing package update of rcom, and hence of
rscroxy, from within Rgui, since these packages are already loaded when
the R command line becomes available within Rgui.
Is it OK to comment out those lines temporarily from Rprofile.site in
order do the package update?
Starting R with the command line
RGui --vanilla
starts R without reading Rprofile.site,
then you can safely update everything.

Re: [Rcom-l] status RExcel, rcom, rscproxy, R2.8.0: confused still
(D)COM server 2.5.0 does not work with R 2.8.0 because the inner workings of R have been changed. We already have a beta version of (D)COM server 3.0 working with R 2.8.0, and Thomas already posted to the list where to get it.

There is a new version of RExcelInstaller on CRAN, and it installs a slightly improved version of RExcel. The installer now checks of rcom is available and gives appropriate warnings if not. There also is a new version of RAndFriendsLight on the rcom web site. It already includes R 2.8.0. The full version of RAndFriends is not available yet.

Re: [Rcom-l] MISSING RCOM 1.0 Type Library
Murray, you probably had R-2.4.1 installed on this machine at the given location and did not update fully. The package rcom creates a registry entry. This is done when you run the command comRegisterRegistry() at first use. When you install a new version of R, you need to install the latest version of rcom and run this command again. Please install package rcom for R-2.8.0 from CRAN and run this command. Then try again.

When I open Excel, then go to RExcel-Set R Server, the Foreground Radio Box is greyed out. The two ways I've been able to get RExcel to work are to (a) choose Background and check the Remote checkbox, then either leave Server address blank, or put in my local machine's name, then click save, then click close and go about using RExcel or (b) Click on the Remote check box, click Save (this activates the Foreground radio box), select Foreground, uncheck Remote, then check RGui visible, then click Save (this greys out Foreground, but it is still selected), then click close and go about using RExcel. 2) The R Server settings don't seem to be persistent from Excel session to Excel session, so every time I open up a new excel, I have to redo the server settings 3) If I try to put a dataframe into the R session and name it with a single-character name, I get an unhandled error in the VBA code; if I try to name it with a number as the last character, and the second to last character is not an underscore, I get a dialog box informing me that the name I've chosen is not a valid dataframe name.

Hi everybody,
I am new to R-excel-add in and trying to connect my R code with excel.
My R version is 2.5.1 and the R (D)com is V 2.01.
The code I am using to call R is
Call RInterface.RRun(source( Replace(ThisWorkbook.Path, \, /)
/PORTO)) , where PORTO is the R source file containing my code.
Please help me sort the problem. Thank you all.

Re: [Rcom-l] Detecting if RExcel is installed
On Jul 17, 2008, at 11:58 PM, Andrew McLachlan wrote: Thank you Erich I have just been reading about the AddIns collection and was wondering whether to use that approach or not. Your reply has stopped me wondering :-) and I will be adding your code to my project. During my testing of the functions below, I found that they worked as expected. That is, when RExcel2007 in the Add-ins list was checked, the result was True, and when RExcel2007 in the Add-ins list was unchecked, the result was False. However, I did a further test and got an unexpected result. I unchecked RExcel2007 to uninstall it and then installed and ran my own add-in that uses RExcel. I found that my own add-in worked and used R correctly. This was unexpected. I had a assumed that if the RExcel add-in was unchecked, then the RExcel functions would be unavailable. Is this because I have added a reference to RExcelVBALib in the Tools Reference list? That is probably the reason, but I have never tested this, therefore I do not know in detail. My guess it the followning. The checkmark does not tell yo if the addin is installed, but if it is active. The fact that the addin is on the list means that it is installed. My guess is that the installed property better should be called activated. I am wondering about my user installing my add-in without RExcel being present and, thereby, generating uncontrolled errors. I am wanting to detect when the RExcel macros are available and when they are not so that I can give a warning to the user when they try to do things that require RExcel. Should I be doing this, do you think? Or, should I just be making sure that I have RExcel properly installed before installing my add-in (my defensive programming nerves start to twitch at the thought!)? You will have to check for yourself. Any thoughts on this would be appreciated.

I just put up
http://rcom.univie.ac.at/download/devel/RExcelInstaller_2.0-33.zip
It should solve the problem Wayne descriped.
Please download and install from local zip file.
Then start R and do
library(RExcelInstaller)
RExcelInstall()
This will install the corrected version.
Please give me feedback if things now work.

Re: [Rcom-l] R(D)COM
We are currently changing the architecture. RExcel became a full CRAN package only recently. Currently, installing RSrv250_pl1.exe installs an outdated version of RExcel, and it even installs in in a now inconvenient place. If you wait for about 2 weeks, we will have new packages and installers for all our stuff. In the meantime you can safely use the foreground server. Felipe Carrillo wrote: Hi all: Is R(D)COM a regular package that can be updated from CRAN or it just gets installed with RExcel? I am asking this because I have deleted my Older RExcel version and R(D)COM was deleted with it and now I don't have a background server again. I took care of this by installing the old RExcel back but I was just wondering and thought that the new version would install R(D)COM with it. Thanks Felipe D.

[Rcom-l] Re: Error
Problem solved. The mechanism for running R files has changed. I am using a textConncetion now. Your R code has calls closeAllConnections and so closes also the connection RExcel is using. As far as I see your code is not opening connections, so you don't have to close either. This is probably a remainder from the original tests when you used the read.table statements which are now commented out. Using a command with global side effects like closeAllConnections is not a good idea in a complex system like RExcel. Doing global stuff in as subroutine called by somebody else (RExcel in out case) is something one should definitely avoid. An additional remark. You also have a lot of implicit print statements when you just use variable names as commands. This commands do not produce output in the RGui window, and they also do not transmit information to Excel. So it would be better to remove these commands also. Your macros also use a lot of Select statements, probably because you used the macro recorder. Instead of Range(J2).Select Range(Selection, Selection.End(xlToRight)).Select Range(Selection, Selection.End(xlDown)).Select Selection.ClearContents you could also do Dim StartCell As Range Set StartCell = Range(J2) Range(StartCell, StartCell.End(xlDown).End(xlToRight)).ClearContents When working with ranges in macros it is not necessary to select them. To work with ranges interactively you have to select them. Therefore, the macro recorder will always use Select, but in your VBA code they are unnecessary.

Re: [Rcom-l] PutArrayFromVBA: numeric vs string
This is an array with mixed data types. This is difficult to handle. I do a lot of analyzing for missing values in Excel sheets, but I cannot do that in VBA easily. What you are doing is not using missing values, but string values as placeholders for missing values. The next release (which is probably at least half a year away) will take care of this more carefully. But you really need to create an Error value in VBA to transfer something as missing. Currently, PutArrayFromVBA assume that all the array elements have the same data type. So you should do some R programming after transfer to clean up missing data. When you read a cell with an NA value into a VBA variable, you do not get a string value, you get another data type! Variant/Error Christian Prinoth wrote: Sorry, that's just one of my concoctions, just replace it with a = array(1, 2, 3, NA, 5, 6, 7, #N/A, 9, 10) Right now I do this: Sub NumArr2R(VarName As String, arr) Dim n As Integer, i As Integer n = ismatrix(arr) If n = 0 Then arr = CStr(arr) ElseIf n = 1 Then arr(LBound(arr)) = CStr(arr(LBound(arr))) ElseIf n = 2 Then arr(LBound(arr), LBound(arr, 2)) = CStr(arr(LBound(arr), LBound(arr, 2))) Else Stop End If putarrayfromvba VarName, arr If n = 0 Or n = 1 Then rrun VarName -as.numeric( VarName ) ElseIf n = 2 Then rrun VarName -matrix(as.numeric( VarName ), UBound(arr) - LBound(arr) + 1 , UBound(arr, 2) - LBound(arr, 2) + 1 ) End If End Sub Which is not very elegant...

Re: [Rcom-l] Unable to change R Server Config
It is probably best to uninstall everything. The Control Panel item Add or Remove Programs should have an item R/Scilab (D)COM server and RExcel1.75 (or similar) This should allow you to uninstall. otherwise, you should do it manually with the following command line C:\Program Files\R\(D)COM Server\bin\StatConnectorSrv.exe /UnRegServer (possibly you have to use a different path) I will roll a new package RAndFriends later today which then will take care of installing a complete working system.

Re: [Rcom-l] How to put/get data from/to autofiltered column?
The defaults are that filtering is respected for dataframes, but not for matrices. NAs also should be handled reasonably for dataframes. How missing values are handled iis configureable. Documenations describes how you can change this behavior in RExcel-Options Jens Oehlschlägel wrote: Dear rcom experts, I started enjoying the power of R(D)COM using Excel. I tried to putArray from an autofiltered column and learned that all values are transferred to R, which is fine using the RespectHidden trick from PutDataframe: doing the filtering in R. However, when trying to reversely getArray the unfiltered data from R to the original range, then data is mis-assigned. This seems to happen in the line a.value = Matrix in ArrayToSheet.

Re: [Rcom-l] Resources for calling Excel from R
This is good advice, but one has to be careful.
In VBA, some objects have default methods.
Sub xxx()
Dim x As Variant
x = Range(A1)
Debug.Print x
End Sub
will work,
but the correct syntax is
x = Range(A1).Value
and you have to do the equivalent of this in you R code.
I cannot supply more examples right know, but this peculiarity
has hit me a few times.

Hello Charilaos-
I admit that using rcom commands to create other objects are rather
confusing. My general premise is this: comGetProperty and
comSetProperty, are used for property events. However, comInvoke is
used for methods and objects. In theory, it's pretty simple, but how
does one tell the difference between a property versus a method using:
comGetObjectInfo...well one cannot.
So, to get around this issue I use the Help menu item from the VBA
editor window: Help Microsoft Visual Basic Help Microsoft Excel
Visual Basic References. Here you will find each parameter that can be
manipulate via rcom; it clearly indicates which are properties, methods,
objects and event etc. This has proven most helpful to me as I use rcom
to dump my subsequent results into Excel, PowerPoint, Word, or Outlook.
Also, I use the following code to better view the parameters that
comGetObjectInfo() returns:
This allows you to view parameters in a more efficient manner
jnk1-comGetObjectInfo(wb)
info.jnk-matrix(jnk1,nrow=length(jnk1),ncol=4,byrow=T)
de(info.jnk)

Let me try this again:
Hello all,
I'm new to rcom, and my focus is to access Excel from R. For
instance, I would like to attempt to read the current spreadsheet.
The problem I am running into is how to find out the proper calls. I
started with looking at the examples in comGetProperty, and in
particular managed to get the following call working:
r - comGetProperty(ws,Range,A1,B4)
My question really is: How could I have figured out the syntax if
noone told me about it?
What I tried is looking at:
comGetObjectInfo(ws)
The output from that is pretty chaotic, so then I tried:
sort(names(comGetObjectInfo(ws)))
This would show me that one of my options there is Range, but

I understand that R will not simply allow me to send retval by reference (which I think I need). In R it will become a 'local variable' to myfunction.

Whenever I need to specify some additional part of R code in quotation marks, VBA goes wild and won't accept it, as it always gives the following error: Compile error: Expected: list separator or ) For example, in the following 3 lines of code, I'm trying to take some data from Excel, import into R under the array name PCContribution, convert it to a matrix, and then plot it. Seems simple enough, right? When I get to the third line/entry of code below though, the above error always comes up and it highlights the word single when it presents the error. Call Rinterface.PutArray(PCContribution, Range(Graphs!A1:C20), WithRownames:=False, WithColNames:=False) Call Rinterface.RRun(PCMatrix-ts(matrix(PCContribution, ncol=2, nrow=27, byrow=FALSE), start =c(1983, 3), frequency = 3)) Call Rinterface.RRun(testing-plot((PCMatrix), plot.type = single)) Can anyone help? It's really frustrating because I know the code is right and should produce the correct graph - it's just the syntax with the quotation marks, I guess, that doesn't work in VBA but is what is required in R.

Re: [Rcom-l] Error in R matlab connection
I do not have matlab,
so I do not know the mechanism of creatinf a COM object in matlab.
I notice that you are using Eval for calls with reaturn values
AND for calls without return values.
The R COM object has 2 methods,
Evaluate and EvaluateNoRerurn
You should use the second one for assigments like your
g-

Hi,
Maybe the answer to this question has been given before but I could not
figure out how to search the threads in the list.
My question is about the error message in matlab,
Invoke Error, Dispatch Exception: Object is static; operation not allowed
What I do is below:
[s,m] = openR;
% connection is established correctly
r = evalR('ls()')
r = []
%the connection works and there is no variables defined in R yet
evalR('library(ordpcalg)')
% I load a library
evalR('g - randomDAG(10,0.2)')
% I call a function that is in ordpcalg package loaded above
r = evalR('ls()')
r = 'g'
% randomDAG works!
evalR('g - randomDAG2(10,0.2,4,0.5)')
??? Error using == evalR
Problem evaluating command print(g2 - randomDAG2(10,0.2,4,0.5)).
Invoke Error, Dispatch Exception: Object is static; operation not allowed
% I call randomDAG2 (another function in ordpcalg) but is gives the
above error.
The function call is correct and works in RGui. I am working on windows
and using R-2.5.1 and Matlab 7.0.0.19920(R14).
What can the problem be?
Thanks,
Mehmet

Re: [Rcom-l] rinterface RRun-RRunFile
in r prograns, you need single forward slashes as path separators. you also might use double backslashes. so the double forward slashes are your problem. my example showed you which slashes to use where.
