*Summary: * During package loading the library function calls file.info to determine if a file is a directory. This uselessly invokes getpwuid and getgrgid which can be expensive if the user/group database are held on a network. Note that file_test ALSO uses file.info for the same purpose Suggest rebuilding file_test to use ‘stat’ based call for directory search, and using file_test in

Hi , I tried to do the following . Before I execute the R script , i tried to clear the work space using rm(list = ls(all = TRUE)); . I get the following back trace .

Dear list, I am trying to implement a publish-subscribe mechanism in for an embedded R interpreter. But somehow my registered closures seem to get collected by the GC, even though I have protected them. I have reducted my code to the following sample. Sorry if it is a little verbose. The first couple of call of calls still work, but at some point one of the callbacks (callback1 in my

Hi I think I have asked these questions earlier, but I been able to find answers from the documentation (which I found poorly written in several places). Will someone be kind enough to give me answers and enlighten me? (as in explain with CODE?) I want to embed R in my application and use the fPortfolio package for carrying out risk management computations. Right now I'm reading the Rmetrics

Hello. I'm a new user of R, and I have a question regarding the use of aov and lm-functions. I'm doing a fractional factorial experiment at our production site, and I need to familiarize myself with the analysis before I conduct the experiment. I've been working my way through the examples provided at http://www.itl.nist.gov/div898/handbook/pri/section4/pri472.htm

Greetings all, Recently ran into a seg fault the keeps reoccurring whenever R-java is used (I believe). Not sure if this is an R issue or an openjdk issue so I'm trying to cover all bases with this report. I tried downgrading R version from 3.4.0 to 3.3.3 with the same results. Also tried downgrading java version from 1.8 to 1.7 with no luck. Running on a fully updated CentOS 7 x86_64,

Hi, R_tryEval, exported in Rinternals.h but not part of the API, is currently defined as: R_tryEval(SEXP e, SEXP env, int *ErrorOccurred); I'm trying to embed R in an application (basically yet another GUI), and this has been very helpful to catch errors. It would be even more helpful if it also gave access to the visibility flag. I can wrap this in a call to withVisible, and that works

On an azure centos VM, I can reproduce this bug which reports either: *** caught segfault *** address 0x70000006a, cause 'memory not mapped' (crash) Or incompatible types (from builtin to integer) in subassignment type fix (no crash) Like Gabriel, I could not reproduce the bug on a mac laptop.

The following code crashes after about 300 iterations on my?x86_64-w64-mingw32?machine on R 3.5.2 --vanilla.?? Others have duplicated this (see?https://github.com/tidyverse/magrittr/issues/190?if necessary), but I don't know how machine/OS-dependent it may be.?? If it doesn't crash for you, please try increasing the length of the x vector. Substituting the commented-out line for the one

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

I'm new to R development, so this may be a trivial question. In C, How do you convert a SEXP value returned by an R function to a primitive C type (int, double, char, array, etc.)? I've tried using the INTEGER(x), VECTOR_ELT(x,i), and similar functions found in /src/ include/Rinternals.h, but doing so results in incorrect results or a seg-fault. For example, I modified

Hello, I have successfully (hopefully) configured samba to run in Kubernetes pods, basically I have a pod (i.e. container) that run winbindd and join the Windows AD, and a pod (i.e. container) that run smbd. I have used socat to allow the unix socket communication between winbindd and smbd pods: *** winbindd pod *** UID??????? PID? PPID? C STIME TTY????????? TIME CMD root???????? 1???? 0? 0

Hi, I want to be able to get at the described class in my shared behaviour.

I've got a file that's approximately 2.2GB and it seems to be foiling file.info().

I think there is a memory bug in `substr` that is triggered by a UTF-8 corner case: an incomplete UTF-8 byte sequence at the end of a string.? With a valgrind level 2 instrumented build of R-devel I get: > string <- "abc\xEE"??? # \xEE indicates the start of a 3 byte UTF-8 sequence > Encoding(string) <- "UTF-8" > substr(string, 1, 10) ==15375== Invalid read of

Hi, I'd like to construct an R list object in C++, fill it with relevant data, and pass it to an R function which will return a different list object back. I have browsed through all the R manuals, and examples under tests/Embedding, but can't figure out the correct way. Below is my code snippet: #include <Rinternals.h> // Rf_initEmbeddedR and other setups already performed

I'm trying to get a reference to this object in C SWX.RET[1:6,c("SBI,"SPI","SII")] While i am able to access and use a plain SWX.RET object, I'm getting confused on how to create an object with the array subscripts like above. Here is what I tried to do. It doesn't work because "[" is obviously not an operation or function on SWX.RET. So how do I
