similar to: R_parseVector and syntax error [was: error messages while parsing with rniParse]

Hi, Forum newb here, looking for some help. Have been trying to install an R-Java interface to make R calls from Java. JRI's configure script runs fine, but when it comes to make, I get the "error: too few arguments to function 'R_ParseVector'" Java runs fine. R runs fine. But I can't get this .jar file created. <grumble> Any help would be appreciated immensely,

May I know if we have any C api(or any other way) in retrieving the parse error message after calling R_ParseVector? -- View this message in context: http://r.789695.n4.nabble.com/C-API-for-parse-error-tp4689662.html Sent from the R devel mailing list archive at Nabble.com.

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

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

Hi again, Beside R_ParseVector()'s possible inconsistent behavior, R's handling of zero-length named elements does not seem consistent either: ``` > lst <- list() > lst[[""]] <- 1 > names(lst) [1] "" > list("" = 1) Error: attempt to use zero-length variable name ``` Should the parser be made to accept as valid what is otherwise possible

Thanks for the quick response Tomas. The same error is indeed happening when trying to have a zero-length variable name in an environment. The surprising bit is then "why is this happening during parsing" (that is why are variables assigned to an environment) ? We are otherwise aware that the error is not occurring in the R console, but can be traced to a call to R_ParseVector() in

Hi Simon, Widespread errors would have caught my earlier as the way that code is using only one initialization of the embedded R, is used quite a bit, and is covered by quite a few unit tests. This is the only situation I am aware of in which an error occurs. What is a "correct context", or initial context, the code should from ? Searching for "context" in the R-exts manual

Dear all, my aim is to integrate R in an interactive visualisation software called Bulk Analyzer developed by VrVis (http://www.vrvis.at). the code: SEXP e, tmp; ParseStatus status; PROTECT(tmp = mkString("x <- c(1.234,-3.45)")); PrintValue(tmp); PROTECT(e = R_ParseVector(tmp, -1, &status, R_NilValue)); PrintValue(e); UNPROTECT(2); produces the following output: [1] "x

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

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

Laurent, the main point here is that ParseVector() just like any other R API has to be called in a correct context since it can raise errors so the issue was that your C code has a bug of not setting R correctly (my guess would be your'e not creating the initial context necessary in embedded R). There are many different errors, your is just one of many that can occur - any R API call that

Hola, es la primera vez que mando un correo a cualquiera de las listas de correo de R y no se si esta consulta se ajusta al próposito de la r-help list o debería haberlo mandado a otra de las listas que hay. Mi problema es el siguiente: Estoy desarrollando un programa en java con llamadas a R y no puedo usar jri 0.4-1 con la version 2.7 o 2.6 de R. Curiosamente si me funciona si uso jri 0.4 o la

Dear R-Help, I am trying to get JRI (the rJava interface allowing Java to connect to R) to work. I was able to run it a week ago when I was doing some testing using Java 1.5. However, I am developing a GUI application using some of the new Java 1.6 features and I just can't get JRI to work with this setup. Here is what I get: Cannot find JRI native library! Please make sure that the JRI

Hi all, I am writing R code and I want to interface with JAVA i.e. I want to call R from JAVA. That's why i have installed JRI on my machine. There is also documentation available in "Javadoc". But as i am very new to JAVA and well as R, I don't understand much of it. If someone is using this package i.e. JRI, please let me know whether i am going in right direction or not.

Hello All I am trying to get the JRI examples from rJava to work on Windows XP and failing. (And as a more general and connected question is there any review/summary of front-end software for R?) I have installed rJava from the Windows binary supplied. I compile and run the example supplied (rtest.java) and get the results below. I do not think the notes about a deprecated API are a problem. But
