similar to: On RObjectTables

We recently started noticing freezes that appear only on 32bit systems (both linux and windows) with a relatively recent versions of R 3.2.0, including the RC. It looks like the problem can be traced back to the use of R_ObjectTables (see R_ext/Callbacks.h) The problem is a bit difficult to reproduce because it does not appear on x64 and because the official R interface to this functionality, the

Hello all, I am trying to port the package RProtoBuf to windows. The developers of RProtoBuf have given me some helpful pointers so far, but now I am stuck. After having made what I think are the necessary changes to the package to compile on windows, "R CMD build RProtoBuf" outputs a somewhat cryptic error ("This application has requested the Runtime to terminate it in an unusual

Hi, I notice that the CRAN binary for the macOS version of RProtoBuf is built against quite an old version of protocol buffers (from 2014, before v3 format support was added). the windows version is (blessedly) kept up-to-date, but I'd like to float the suggestion that the macOS version get an update too. with thanks jonathon

Hello everybody, by the way, speaking about the r-cran-rcurl package in Ubuntu, the versions in trusty and vivid are linked by error to the "NSS" flavour of libcurl3 instead of the "OpenSSL flavour", which cause at least problems when using the CRAN devtools package. A bit more details are available in the Debian bug tracking system (https://bugs.debian.org/786473). I am not

A new package "g.data" is available on CRAN, to create and maintain databases that work more like the S-Plus model. Here's the official Description for g.data (v1.2): Create and maintain delayed-data packages (DDP's). Data stored in a DDP are available on demand, but do not take up memory until requested. You attach a DDP with g.data.attach(), then read from it and assign

I would like to propose that Rf_mkString(NULL) and Rf_mkChar(NULL) return NA rather than segfault. Case: the mkString() and mkChar() functions are convenient to wrap strings returned by e.g. external C libraries into an R vector. However sometimes a library returns NULL instead of a string when the result is unavailable. In some C libraries this can happen unexpectedly or is even undocumented. A

Hello, I've been trying to make LinkingTo work when the package linked to has c++ code. I've put dumb packages to illustrate this emails here ; http://addictedtor.free.fr/misc/linkingto Package A defines this C++ class: class A { public: A() ; ~A() ; SEXP hello() ; } ; Package B has this function : SEXP say_hello(){ A a ; return a.hello() ; } headers of package A are copied

A new version of the ggplot2 web application is available at http://www.yeroon.net/ggplot2. New features include 1D geom?s (histogram,?density, freqpoly), syntax mode (by clicking the tiny arrow at the?bottom), and some additional facet options. Furthermore some minor?improvements and fixes, most notably for Internet Explorer. As usual, a little demo video that shows how to use the new features:

Hi, I have been enjoying r for some time now, but was wondering about working with larger data files. When I try to load in big files with more than 20,000 records, the programs seems unbable to store all the records. Is there some way that I can increase the size of records that I work with? Ideally I would like to work with census data which can hold a million records. Greg

I think that this is because `[<-` dispatches on S4 methods only if the first argument is S4. ?"[<-" says: "These operators are also implicit S4 generics, but as primitives, S4 methods will be dispatched only on S4 objects ?x?."

I would like to print some tables and figures to a PDF device on a CentOS 5 vps. However, I cannot seem to get the latex function from Hmisc working. I followed the example, and got an error: sh: xdvi: command not found. I tried installing the 'tetex-xdvi' linux package, and now it returns: Error: Can't open display. I guess the reason for this is that the machine is a VPS terminal, so

I am using numerical optimization to fit a 1 parameter model, in which the input parameter is bounded. I am currently using optimize(), however, the problem turns out to have local minima, and optimize does not always seem to find the global minimum. I could to write a wrapping function that tries multiple intervals or starting values, but I would prefer a package that has built-in methods to make

Is there a way to get the status code of a pipe() command? The documentation suggests that it might be returned by close, however this does not seem to be the case. con <- pipe("cat /etc/passwd", "r") stream <- readLines(con, n = 10) err <- close(con) print(err)

I am looking for a function to flatten a list to a list of only 1 level deep. Very similar to unlist, however I don't want to turn it into a vector because then everything will be casted to character vectors: x <- list(name="Jeroen", age=27, married=FALSE, home=list(country="Netherlands", city="Utrecht")) unlist(x) This function sort of does it: flatlist

I use recordPlot() to save plots to disk that I render later to a variety of formats. This works fine for base R plots and ggplot2 plots, and also used to work for lattice plots. However somewhere in version 2.14 things stopped working for lattice plots. Here is an example: library(lattice); histogram(rnorm(100)); x <- recordPlot(); saveRDS(x, "myplot.rds"); y <-
