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 all constants "object numbering" should be printed: out << '%' << ctxt.RNumbering[V]; // V = CaseValue in our case....

...m 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 R-ish. PrintValue() seems promising (it understands when I change options(digits) but I did not get it to print a single value. I tried SEXP variable; PrintValue(VECTOR_ELT(variable, i)); which lead to crash, while PrintValue(variable); prints the whole vector. StringFromReal() (and printing as CHAR)...

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.

...Syntax errors are causing my rterm to shut down, apparently because I'm not catching the exceptions that are thrown. How are exceptions thrown? 2. If I want to get R to give me a string showing how an existing variable would be printed, what's the normal procedure? I tried calling "PrintValue", passing it the Rinternals export "R_LastvalueSymbol", but I just get an access violation in R.DLL. This could be because I'm not handling the export properly (DLLs normally export entry points, not pointers to variables, so I had to try to guess what indirection was being used...

...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, it will print the right value. My debug result shows that the variable "colNames" failed the "isObject" call. I am not sure whether this is a new feature or bug. Anyone can help? Thanks, Gang Liang

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 <- c(1.234,-3.45)" expression(x <- c(1, -3)) I'm using MS Visual C++. The code works fine in a small test project with the same R startup...

Hi, I want to print real numbers in C code with different values for digits. How to do that? As I have understood, what I should do is to call StringFromReal() which calls FormatReal(), that one suggests the parameters (width, decimal places and exponential form). FormatReal() includes eps = pow(10.0, -(double)R_print.digits); So I guess I have to change the value of R_print.digits.

Rather, Constants inside...

Hi the list, Is there a way to give a matrix to a C function, and then to use it as a matrix ? I write a function to print a matrix, but I use it as a vector : 1. void printMatrix(double *mTraj,int *nbCol, int *nbLigne){ 2. int i=0,j=0; 3. for(i=0 ; i < *nbLigne ; i++){ 4. for(j=0 ; j < *nbCol ; j++){ 5. Rprintf(" %f",mTraj[i * *nbCol + j]); 6. } 7.

Dear All, I've read the manual on "Writing R Extensions" and in particular the part on calling R from C. (Most of the manual is about calling C from R, not the other way around.) The good news is that I can now call _some_ R from C, specifically the R functions which have C header files. However it isn't clear to me how to call R functions that are written in R. I

Hi, I think this is a bug (even though I can't find documentation explicitly saying that it should work). Basically, Rf_PrintValue(obj) fails when 'obj' is an S4 object that should be printed using show() rather than print(). From the error message I'm guessing that the need to use show is detected correctly but then show is not found. "cbind2" in the code below is just a representative object, the same...
