similar to: R_ParseVector problem: it's cutting off after the decimal point

After a long processing, I was able to create a version of a small C# class that was able to emulate the rproxy by P/Invoke. This is mostly to find a workaround a performance problem of the StatConnector. It's almost work but ... I have strange memory exception when I call the print function. The variable seems to not survive from one call to the other. As there is no debug symbol for

Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM. I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper

Dear r-helpers, I have been trying to invoke R from Java in a Windows 2000 computer (unfortunately). All my environment variables seem to be properly set, everything seems to be in order, but I obtaining a Fatal error: unable to open the base package error window. Also, the output of the invoker is Loading RInterpreter library R_HOME: R_HOME=C:/Programas/R RVersion: R_VERSION=1.6.1 whereas

Dear R-developers, even though I may not be the first one to encounter the problem described below, I would really appreciate some help or a link to a forum where this topic is being discussed. Probably I am simply misinformed on the usage of structRstart but see for youselve. I did check multiple forums and the whole internet on the topic without success. I am using the shared library version

Hi guys, We are currently running a clustered samba setup with 3 nodes very successfully. The only thing that bothers me is that whenever we change permissions on a shared directory, we have to restart ctdb on the nodes where affected users are still connected to push the changed permissions to the hosts by basically killing their connections and thus forcing them to reconnect. However,

Hello xen-users ! I am coming for help concerning the just released 4.0 version. Install has worked rather well on my Debian Lenny. I have just had a few bugs for which I have found the answer looking around on this list. I have created a Debian Lenny domU which boots up just fine. The only problem is that I am unable to get a console prompt when using "xm console nameofdomU". I do see

Hi all. I found next code when switch instruction differs: Engine.logf("right switch has extra case %r") << CaseValue; Where CaseValue is a ConstantInt object. Looking how logf works I found that it invokes DiffConsumer::printValue method for CaseValue. And here I found that CaseValue itself will never printed. On first look how DiffConsumer::printValue works it seems that for

Dear R developers, just a quick question: I noted that R_ParseVector () has gained an additional parameter (since SVN rev. 39999). Since R_ParseVector () is part of the public API, I'm wondering, whether this API change was intentional or not. Either way is fine with me, but in order to make sure the next release of RKWard will be compilable with R 2.5.0, I'd like to make sure,

Hi r-devel, The R_ParseVector has been changed in R-2.5.0, and there is a simple description about the 4th argument at http://stat.ethz.ch/R-manual/R-patched/NEWS, it says that: "R_ParseVector() has a new 4th argument 'SEXP srcfile' allowing source references to be attached to the returned expression list. " I do not quite understand the purpose of adding the 4th argument. Would

I found the following code comment in `src/main/gram.c`: ``` /* Memory leak yyparse(), as generated by bison, allocates extra space for the parser stack using malloc(). Unfortunately this means that there is a memory leak in case of an R error (long-jump). In principle, we could define yyoverflow() to relocate the parser stacks for bison and allocate say on the R heap, but yyoverflow() is

Dear Laurent, could you please provide a complete reproducible example where parsing results in a crash of R? Calling parse(text="list(''=123") from R works fine for me (gives Error: attempt to use zero-length variable name). I don't think the problem you observed could be related to the memory leak. The leak is on the heap, not stack. Zero-length names of elements in a

Hello, [I'm redirecting this here from stats-rosuda-devel] When parsing R code through R_parseVector and the code generates an error (syntax error), is there a way to grab the error. It looks like yyerror populates the buffer "R_ParseErrorMsg", but then the variable is not part of the public api. Would it be possible to add yet another entry point to the parser that would

Hi, The behavior of ``` SEXP R_ParseVector(SEXP, int, ParseStatus *, SEXP); ``` defined in `src/include/R_ext/Parse.h` appears to be inconsistent depending on the string to be parsed. Trying to parse a string such as `"list(''=1+"` sets the `ParseStatus` to incomplete parsing error but trying to parse `"list(''=123"` will result in R sending a message to the

Thank for Brian D. Ripley for the answer to my previous question. My aim is to print single values from different real vectors with different digits option. This is quite a possible with Rprintf() but that one supprots printing format as C does, not in R native way (setting digits=7 or printing with "%12.7f" are two quite different things). So I would like to find something more

In 2.8.0/Windows Vista: When 'unique' gives a type error message, it prints out even if errors are being caught: > try(unique(quote(hello)),silent=TRUE) hello This comes from the .Internal unique routine: > try(.Internal(unique(quote(hello),NULL,NULL)),silent=TRUE) hello I guess it is using the internal equivalent of print rather than the internal equivalent of stop.
