similar to: Rprintf will not build in my C++ compiler

I'm looking for a function that lists a few summary stats for a column (or row) of data. I'm aware of summary(x), but that does not give me what I'm looking for. I'm actually looking for something that is very similar to the descriptive statistics tool in excel; i.e. Mean, Std. Error, Std. Deviation, Kurtosis. I'm positive that I came across a function that did this (possibly

I am trying to delete a section of rows from a data frame (based on no condition). Lets say my data frame has 200 rows and I want to delete rows 1 through 25. How would I do this? I know x[ -1, ] deletes the first row (or any desired row). I tried using different variations of this, like x[ -c(1:25), ] but that didn't work. I also tried writting a few functions, for example: deleteRows

I'm trying to calculate the percent change for a time-series variable. Basically the first several observations often look like this, x <- c(100, 0, 0, 150, 130, 0, 0, 200, 0) and then later in the life of the variable they're are generally no more 0's. So when I try to calculate the percent change from one observation to the next, I end up with a lot of NA/Nan/INF, and

I'm trying to find information about how to use Rprintf with a UTF-8 encoded string, and I'm not sure what the right cross-platform usage is. I found an earlier thread about this (http://r.789695.n4.nabble.com/How-to-print-UTF-8-encoded-strings-from-a-C-routine-to-R-s-output-td4724337.html) but it wasn't very helpful. If I want to print a UTF-8 string, I can do one of the

Hello all, I am using Rprintf in a C for loop (from .Call) to print a progress indicator showing the current percent complete. The loop I am doing is an time intensive call to another function. I have noticed that Rprintf does not print to the R-window until the entire loop has been completed. When it reaches the end of the loop it suddenly prints 0 percent to 100 percent in a split second.

Dear R-devel, My g++ complains about the first argument to Rprintf being non-const char *. For example when compiling the line Rprintf("hello world\n"); the following warning is emitted: warning: deprecated conversion from string constant to 'char*' Is there a reason for the non-const? It is curious that Rf_error, which is similar to RPrintf, is const. If there is a need

Hi, I've been using Rprintf from a shared library compiled under various unix flavour for a while now. I get a warning about Rprintf being undefined when constructing the library, but everything works OK after loading. I've also been cross compiling the same library using the mingw32 tools for a while now, but the inclusion of Rprintf seems to be messing up this process. It can't

Is it safe to call Rprintf and REprintf from a background thread? I'm working on a package that makes calls to fprintf(stderr, ...) on a background thread when errors happen, but when I run R CMD check, it says: Compiled code should not call entry points which might terminate R nor write to stdout/stderr instead of to the console, nor the system RNG. Is it safe to replace these calls

Hi, I would appreciate if someone could comment on this problem I am experiencing. I am writing a C++ program to be called from R. In this program, there is a verbose switch that decides whether to print some debugging info using Rprintf. On windows, things work ok. On linux, things are fine in non-verbose mode, but in verbose mode, I get error saying "C stack usage is too close to the

Thanks - I'll find another way to send messages to the main thread for printing. -Winston On Tue, Nov 21, 2017 at 12:42 PM, <luke-tierney at uiowa.edu> wrote: > On Tue, 21 Nov 2017, Winston Chang wrote: > >> Is it safe to call Rprintf and REprintf from a background thread?

Does not seem to be a straight error with LLVM itself, but rather the tools, linking issues, here are the errors: Opt: 30> Creating library R:\SDKs\llvm\trunk_VC8_building\lib\Debug\opt.lib and object R:\SDKs\llvm\trunk_VC8_building\lib\Debug\opt.exp 30>LLVMScalarOpts.lib(IndVarSimplify.obj) : error LNK2019: unresolved external symbol "public: bool __thiscall

thank you! yes, i guess that is the problem. unfortunately libcmt doesn't work. could it have another name for lli? The function missing seems to be part of libcmt since i get a similar error on linking if i remove the libcmt D:\llvm\examples\helloworld>lli -load=libcmt hello.bc Error opening 'libcmt': libcmt: Can't open: The specified module could not be found.

I assume you are using Visual Studio as your build tool? The LLVM project set turns into a bunch of Visual Studio project files, and my experience has been that they do not always coordinate correctly. Often just running the build again will solve a problem like this. I'm not really familiar with the sanitizers so I don't have any ideas about the specific error, if re-running the build

I've followed all the LLVM+clang build-from-source instructions for Windows using MSVC++ 2008. It all builds fine. I initially had troubling getting any linking to work at all until I made sure to have the right environment variables set using a wrapper batch script. Now C programs compile, link, and execute fine, but C++ programs don't link, not even a simple "hello, world"

I'm trying to write R functions into VBA code. I've done this many other times in other documents and everything has run great. But today I keep recieving an error message "Run-time error '1004': Application-defined or object-defined error." Has anyone else encountered this same error message? I do not recieve this error in the document when running regular VBA code.

Hi guys, I discovered xapian today and I'm trying it because it looks promising compared to other FTS engines. However I'm in a windows environment so it's a bit painful to set up as there is no official binaries. I've heard about http://www.flax.co.uk/xapian_binaries And I'm trying to build their latest release (1.2.8). After a few tries I manage to compile everything with
