similar to: is it necessary to always register C routines with R_registerRoutines?

Hello dear R-help mailing list. Looks like the same issue in Russian: library(RCurl) library(XML) u = " http://www.cian.ru/cat.php?deal_type=2&obl_id=1&room1=1" a = getURL(u) a # Here - the Russian is fine. a2 <- htmlParse(a) a2 # Here it is a mess... None of these seem to fix it: htmlParse(a, encoding = "windows-1251") htmlParse(a, encoding =

I am writing a package, which contains several functions and variables. The variables are for internal use by functions. Functions are ment to be callable by a user. However, the function cannot access these variables. The package contains only R code, and was created using package.skeleton package.skeleton(name="ac9", list=c(ls(pattern="(AB2)|(ac9)"),

It seems, I don't understand something, or there is a bug in R. I have made some experiments after my yesterday post about using "=" with -e switch to the Rscript. Now, I've found: (1) C:\users\wl\trainings\r>rscript --verbose -e "mean(x=1:3)" running 'C:\Program Files\R\bin\Rterm.exe --slave --no-restore -e mean(x=1:3)' Error in -args : invalid

Hello, I do not have an account on R Bugzilla, so I will post my bug report here. I want to report a very old bug in base R *source()* function. It relates to sourcing some R scripts in UTF-8 encoding on Windows machines. For some reason if the UTF-8 script is containing cyrillic letter *"?"*, the script execution is interrupted directly on this letter (btw the same scripts are sourcing

Thanks for the pointers to the above

Hi, I want to read a text file into R with .Call(). So I define some NEW_CHARACTER() to store the chracters read and use SET_STRING_ELT to fill the elements. e.g. PROTECT(qNames = NEW_CHARACTER(10000)); char *foo; // This foo holds the string I want. while(foo = readLine(FN)){ SET_STRING_ELT(qNames, i, mkChar(foo))); } In this way, I can get the desired character from qNames. The only problem

(the same mail was sent to the author) When I called the function DEoptim with control=list(strategy=1) or control=list(strategy=2) I got the error: Error in mui[rtd + 1, i] : incorrect number of dimensions Analysis of the source code of the DEoptim reveals the following fragment if (con$strategy > 5) st <- con$strategy - 5 ## binomial crossover else { st <-

On Windows this warning may be a false positive if R cannot find "objdump.exe" which is required for this check. I think this is actually a bug in R because it should be looking for "objdump.exe" inside BINPREF (where gcc is) rather than on the PATH. Can you check if you get the same warning if you upload the package to https://win-builder.r-project.org ? On Fri, Feb 23,

I recently noticed a change between R-3.3.3 and R-3.4.0 in the definition of the R_CMethodDef struct. typedef struct { const char *name; DL_FUNC fun; int numArgs; - R_NativePrimitiveArgType *types; - R_NativeArgStyle *styles; - } R_CMethodDef; I suspect this is the reason that packages installed by R-3.4.0 and loaded into R-3.3.3 will crash the

My understanding (which could be wrong) is that when you source a file, it first gets translated to your native locale and then parsed. When you parse a character vector, it does not get translated. In your locale, every "?" character (U+044F) gets replaced by the byte "\xFF": > iconv("\u044f", "UTF-8", "Windows-1251") [1]

Dear list, I am trying to update a package to pass the CRAN-checks. But I am struggling with the following note: File 'psgp/libs/i386/psgp.dll': Found no calls to: 'R_registerRoutines', 'R_useDynamicSymbols' File 'psgp/libs/x64/psgp.dll': Found no calls to: 'R_registerRoutines', 'R_useDynamicSymbols' It is good practice to register native

Sorry, resending with correct subject line. I didn't find the development version of your package but the latest version archived on CRAN uses Rcpp, RcppArmadillo. Since the latest versions of Rcpp and Armadillo support registration, it may be something related to RcppAttributes() or similar. I think that you don't need to do registration manually. I had a similar problem but when I

Thanks a lot for your answer Jeroen! I should have mentioned that I had actually only checked with the win-builder, as I did not have R-devel installed on my computer. But based on your answer I installed R-devel locally on a Linux-server (Redhat), and the package could be checked without the NOTE. So you might be right that this is a windows issue. However, another package that I am maintaining

Hello folks, I'm embarking on a project to embed R into the Apache web server, and I'd like your help. Currently, I'm looking for a way for R code to call back into a shared library from which the R shared library was loaded. Essentially, apache starts and loads mod_R.so which runs an initialization routine which calls Rf_initEmbeddedR() and the following code: /* override to

Dear People, I'm trying to write an R wrapper for a C++ library, using .Call. I've never used .Call before. I'm currently having some difficulties converting a R character string to a C one. Here is a little test program. #include <R.h> #include <Rinternals.h> #include <stdio.h> SEXP testfn(SEXP chstr) { char * charptr = CHAR(chstr); printf("%s",

Hello: I was hoping to get some advice about how to return a tree (basically a linked list -- with each node containing a parent, left, and right node pointers) from a C routine back into R. Each node itself contains several attributes (a double, a char *, an int, and a void * ) Initially I was thinking I could just return to R a SEXP containing a pointer to the Root Node, but then realized

Hi, I have an SEXP obj in a C function called via .Call(). The obj is protected (in fact it is an argument to .Call and therefore automatically protected). If I set an attribute of obj does the attribute become protected too? Here is an example SEXP foo(SEXP obj) { SET_NAMES(obj, NEW_CHARACTER(3)); /* are names protected or not? */ ... } Thanks, Vadim [[alternative HTML version

Hi, It seems that new("externalptr") is always returning the same instance, and not a new one as one would expect from a call to new(). Of course this is hard to observe: > new("externalptr") <pointer: (nil)> > new("externalptr") <pointer: (nil)> since not a lot of details are displayed. For example, it's easy to see that 2
