similar to: FW: Parse Errors

Dear R Development Team, Using Thomas Baier's R Com Server -- or a dll I am building which supports an evaluate function that is based on Baier's function R_Proxy_evaluate contained in proxy_impl.c -- when I issue an invalid command to R such as "plo(x)" the program crashes. There is code in R_Proxy_evaluate to test for a parse error before actually generating code and issuing

Hello R developers, Platform: Windows 2000. Compiler: GNU GCC - 2.95.2 (CRTDLL) I have a C function for evaluating commands using eval(SEXP,SEXP) which is included in a personal make of R.dll. (Similiar to R_Proxy_evaluate() in rproxy_impl.c) Using SETJMP to catch errors works but there is a problem. For example, the following code: if (SETJMP(R_ToplevelContext->cjmpbuf)) //

Dear R developers, I am building an ActiveX Com wrapper for R. I have successfully implemented an Evaluate function using rproxy_impl.c and rtest.c as examples. The Com object as it stands at the moment is similar to Thomas Baier's automation server StatConnectorSrv.exe except that it does not use the Proxy. My goal it to include a couple of activeX controls in the library: One to provide a

Hello, I am trying to dynamically create/define a function inside of another function (as part of a package.) I build a string that looks something like this: "x + y" and what I need to do is define a function f <- function(x,y) { x+y }. This function "string" is much more complex than this example and depends on other variables so there is no way to predict what the

All, I am in need of some help. I''ve run into a problem that I am not able to fix or even troubleshoot. I am trying to run Mongrel as a service on Win32. Basically, my problem is that running Mongrel as a service works fine. Fine until I change the configuration (using service::remove and service::install) to use --prefix. I must have this as I am running multiple webapps and app

While doing some embedded programming and trying to figure out how to generate a hand coded SEXP equivalent of the line "t.test(x,conf.level=(1-p))$conf.int[2]" I had an idea for an addition to the embedded API. There are a number of hidden or static parse functions (R_ParseBuffer, R_Parse1Buffer, etc.) which take an IoBuffer* and returns a parsed tree. If one or more of these

A common need in R frontends is to provide some sort of read, (parse), evaluate, print loop. However, there are also a number of points where frontends may want to differ from the standard REPL as available e.g. in R_ReplDLLdo1(). First some thoughts on what is needed, and what is already there, or missing. If you want to skip over this, a short summary is provided in the second half, below

Dear R Community, I am trying to create a com dll wrapper for R in a mannor similiar to the R Com Server by Thomas Baier except that I would much rather avoid using the proxy dll ("Rproxy.dll"). Perhaps I don't really understand the reason for going throug the proxy in the first place, but it seems like an unnecessary indirection for an application which is not intended to use DCom.

Hi, An observation on this feature, which I may have completely misunderstood, so flame away if I am being dumb :) Looking at the code, setting "limitonpeers=yes" causes all user and peer calls to be ref-counted as if they are peer calls (assuming a user and peer of the same name exist). A side-effect of this is that an incoming call seems to have its call-limit evaluated based on the

Hi, me again Still trying to run diablo using wine. This time i included: The output when i run : wine setup.exe The listing of my wine-c (c:\) directory. The listing of my config file in the \.wine directory in the users directory Don't give me the answer, u don't have to breast feed me! But tell me if i can fix it without having any programming skills or knowledges of how wine works

Hello R Users, Using: Windows 2000, R version 1.2.0 In the installed directory "etc" there is a file named rgb.txt containing definitions of [all?] the built in colors. I tried to edit this file to add a color as well as change an existing color. My efforts have had no effect. Is this the expected behavior? Is it possible to change or add to the built-in colors? Thanks, Don Wingate.

Hello R developers, Windows 2000 R Version 1.2.2 I am running using R.dll in a Windows application. It is loaded into memory when needed, used as required, and then (hopefully) destroyed while the application continues with other, unrelated activities. The problem is that I can't find any way to free all memory used by R without terminating the process in which R is running, which I

The Wine development release 1.9.19 is now available. What's new in this release (see below for details): - Initial version of a udev bus driver for HID. - Various improvements in joystick support. - Initial implementation of DC rendering in Direct2D. - Improved metafile support in GDI+. - Various bug fixes. The source is available from the following locations:

I'm running samba3.0.23 on a fedora core 4 box. I successfully joined the samba server into an AD and shared home directories on the fc4 box. (Actually, the home directories on that fc4 box are mounted from a NFS server) I can access the top level of my home directory without any problems because the permission is set as 755. But I can't access directores with permissions like 700. So I

Using Thomas Baier's DCOM server I can do the following (in Windows 2000): I create a slider in Excel, and the sliders On_Change event triggers a call to R. This call redraws an R graph, and so I have animated R graphics controlled by Excel's slider. The problem is that Excel needs focus so i can grab the slider, and therefore it partially covers R's graph window. Is there a way to

I have finally got around to putting 4 packages on the Omegahat web site for use on Microsoft Windows. The packages are: RDCOMClient - interactive, dynamic access to arbitrary (D)COM objects from within R that allows one to create COM objects from R and call their methods and access their properties without the need to compile any code specific to the COM object.
