We have an R package which needs to include a JAR file. Is there a canonical directory for it?

Hi, I've successfully used it on a Linux setup, but when I try to load rJava on Windows 7 64-bit (session info below) I get: % R --vanilla > library("rJava") Error : .onLoad failed in loadNamespace() for 'rJava', details: call: dirname(this$RuntimeLib) error: a character vector argument expected Error: package/namespace load failed for 'rJava' >

OK, I managed to create an example without callr, but it is still somewhat cumbersome. Anyway, here it is. Terminal 1: mkfifo fif R --no-readline --slave --no-save --no-restore < fif Terminal 2: cat > fif Sys.getpid() This will make Terminal 1 print the pid of the R process, so we can send a SIGINT: Terminal 3: kill -INT pid The R process is of course still running happily. Terminal 2

I encountered several strange issues when linking to R.dll on Windows and I wonder if anyone of the Windows savvy-folks here had seen some of the issues before and have some explanation. My Rserve links to R dynamic library. That works perfectly on unix boxes and worked fairly well with older MinGW and older R (<=1.7.1). What I do in fact is that I specify -L$(R_HOME)/bin -lR when linking.

Yeah, I get that they are async. What happens is that the background process is not doing anything when the process gets a SIGINT. I.e. the background process is just listening on its standard input. AFAICT for an interactive process such a SIGINT is just swallowed, with a newline outputted to the terminal. But apparently, for this background process, it is not swallowed, and it is triggered

In Mac OS X native version: The R shell wrapper (bin/R) overrides default library search path with DYLD_LIBRARY_PATH and adds (among others) /usr/X11R6/lib. This causes problems when modules need (directly or indirectly) libraries from Apple's frameworks which are masked by X11. Examples for such packages are SJava and RGL. SJava needs JavaVM which in turn loads OpenGL framework. RGL

Unfortunately --interactive also makes the session interactive(), which is bad for me, as it is a background session. In general, I don't want the interactive behavior, but was wondering if I could send as SIGINT to try to interrupt the computation of the background process, and if that does not work, then I would send a SIGKILL and start up another process. It all works nicely, except for

Presumably one could stream over the data twice, the first to get the size, without storing the data. Slower but more memory efficient, unless I'm missing something.

Dear R users / devs, There's been requests in the past for a text editor built into the Rgui for Windows, from which code can be submitted to the R console. Something along the lines of the script editor in S-Plus. Currently Rgui can only display a file read-only in a pager. As far as I can tell there's been little motivation to implement an editor, as most developers use (the

I'm not sure the user would know ;). This is very system-specific issue just because the Linux network stack behaves so differently from other OSes (for purely historical reasons). That makes it hard to abstract as a "feature" for the R sockets that are supposed to be platform-independent. At least TCP_NODELAY is actually part of POSIX so it is on better footing, and disabling

Some issues with the recent R-devel (rsync today) on Darwin: 1) Recent R-devel is a bit misleading concerning the R-framework installation: A new option --enable-R-framework was introduced, but install-Rframework ignores its absence (or --disable-R-framework for that matter) and tries to install the framework anyway in / which fails just after the R itself was copied into /Versions/.... I

Hello, I hope this is the right place to post this. I added readline support to the sftp client. It adds optional --with-readline parameter for configure to enable this feature. You'll of course need to re-run autoheader and autoconf after applying this patch. It's patched against 3.4p1 but should work with any recent openssh. It works fine for me (GNU/Linux) - feel free to test it and

Yes I am running on Rstudio 1.2.5033. I was also running this code without error on Ubuntu in Rstudio. Checking again on the terminal and it does indeed work fine even with large data.frames. Any idea as to what interaction between Rstudio and mclapply causes this? Thanks, Shian On 28 Apr 2020, at 7:29 pm, Simon Urbanek <simon.urbanek at R-project.org<mailto:simon.urbanek at

I need to implement some external callbacks to R and I'm not happy with the current REPL, since it prevents any general solution. Are there plans to improve the current REPL anytime soon? The current approach has some deficiencies you are surely aware of (only one input (=external event loop), the loop is blocked while waiting for input in R_ReadConsole, ...). But the major problem is
