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 all, When using gdb to debug my C code, I use R_PV to show the content of SEXP variables: SEXP sexp; // it is a data.frame SEXP colNames = getAttrib(sexp, R_NameSymbol); A strange thing is that after halting the program: (gdb) p R_PV(colNames) does not show the content of colNames. I am positive my code is right because if I insert "PrintValue(colNames);" in the c code,

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

I was surprised by this: R --interactive -e 'interactive()' bash-3.2$ R -q -e 'interactive()' --interactive > interactive() [1] FALSE > as the command options document says that --interactive should force interactive=TRUE: " When *R* is run in a terminal (via |Rterm.exe| on Windows), it assumes that it is interactive if ?stdin? is connected to a (pseudo-)terminal

list(...), I am looking for a way to interrupt R from a callback: specifically, to interrupt plotting (typically on a cairoDevice, but would be good if it worked with other devices too). Of course, one can interrupt R nicely from the console with Ctrl-C (or Esc in Rgui), but I need to do it from a GUI. Callbacks run in a new thread, so obviously stop() etc will not work. I tried to look into how

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

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

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

I'd like someone familiar with the R options initialization to comment on a difference of behavior within/without mpiexec I have a (.NET) application with embedded R that is proven to run in a single process: ./Sample1.exe on a Debian Linux with R 3.0.2 Running the same code with mpiexec, it fails at the R engine initialization: mpiexec -n 1 ./Sample1.exe Fatal error: you must

Hi all, Can anyone help me understand why an implicit print (i.e. just typing df at the console), is so much slower than an explicit print (i.e. print(df)) in the example below? I see the difference in both Rstudio and in a terminal. # Construct large df as quickly as possible dummy <- 1:18e6 df <- lapply(1:10, function(x) dummy) names(df) <- letters[1:10] class(df) <-

Hi folk, I'm writing a set of small C code to verify whether my pass handle some instruction correctly. One of the instruction I want to test is "va_arg", but compiling my variadic function does not generate any va_arg instruction. Is va_arg deprecated? Will va_arg instruction ever be generated by any front-end? The source code and llvm instructions are appended as follows. the

Neal, FYI, my group has added a flag to llvm-gcc for emitting the va_arg instruction (instead of lowering in the front-end), and we also have an implementation of the VAARG instruction for X86-64. (which is currently not implemented in the LLVM backend). Both of these things will be sent upstream to LLVM soon, pending some more testing and review. If you are dire need of these features now, I

is it possible to run delphi apps/forms(that was build, compiled, and targeted to windows machines) on linux(fc6, suse 10.x) These delphi apps connects to MS SQL server. if it is possible, then I can easily ground all those windows xp machines, that are just use to run these delphi apps... and use linux instead Regards --------------------------------- Got a little couch potato?

Hi, I have an app with Delphi7 + MSSQL, developed during 10 years. Now, the users have asked me about some way to run this app into Linux Fedora Core 2/3. I use Fedora for apps in Java with no problems, but I never heard about Delphi run. I look at WineHQ site about this combination of Delphi + MSSQL but I didn't find. I found some thing about Delphi 7 install and slow behaviour in

Hi, everyone. I'm trying to debug an R-module, written in C, and I'm using gdb for this. How can I print "standard" R objects from within C code? BTW, I'm familiar with the advice to use R_PV given in Writing R Extensions, but it's not working for me. E.g., I get (gdb) p R_PV(x) $1 = void and yet (gdb) p *x $2 = {sxpinfo = {type = 16, obj = 0, named = 0, gp = 0,
