Rf_initEmbeddedR in Windows
Hi All My C++/linux program uses Rf_initEmbeddedR to start R and then calls some R functions. Now I try to port it to Windows. Give the fact that Rf_initEmbeddedR is missing in Windows, I try to use the implmentation in Rserve by Simon Urbanek. When I build in MS Visual Studio, I get the following linking error error LNK2019: unresolved external symbol __imp__putenv referenced in function

linking to R.dll on Win32 - issues with recent MinGW?
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.

Script editor for Windows GUI
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

R's DYLD_LIBRARY_PATH override problems on Mac OS X
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

R-devel with Darwin: some issues (mostly due to latest R.framework changes)
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

eventloop
Hello. I'm writting a glx device and I've some performance problem with the eventloop registration system. The device is not refresh when there's no X event. That's problematic for animation and "smoothness" of display. Should I use threads or fork the R process to get and independant way to refresh my device ? Or do you know another way to refresh it ? Thanks

R as OS X Framework
After the recent discussion about future direction of the Mac OS X port, I was toying with the idea to make R a proper Mac OS X framework. There are several advantages: OS X locates frameworks automatically, therefore any program wishing to link against R has only to specify "-framework R" at link time. Furthermore versioning is supported, i.e. if a program is linked against R 1.7.1

RAqua too hungry of cpu time
It seems that RAqua consumes too much cpu time when doing nothing. I can't see exactly why this is happening. We have few days to fix this up. Any idea (after having look at the code) would be fine. stefano

predict in Pspline package (PR#2714)
To whom it may concern, I don't know whether this is really a bug with the Pspline package or only a problem with my installation. Things work fine in Linux but not in Mac OS X (Darwin). Both system run the latest public versions of R and Pspline. predict.smooth.Pspline produces only NaN instead of predicted values when norder>2: > library (Pspline) > tt <- seq

Failed installation on Mac OSX 10.3 (PR#5697)
I've installed R 1.8.1 on OSX 10.3 (Panther) using the RAqua.pkg and all indications were that the installation was successful.

R-1.5.1 for Darwin/X11
The file ftp://gifi.stat.ucla.edu/pub/R-1.5.1.dmg has grown to 60 MB. It consists of a meta-package and its packages and it will allow you to install binaries for R-1.5.1 and about 300 packages, just by clicking the R-1.5.1.mpkg file. It also install quite a few dylibs in /sw, but not the ones for X11R6 and gnome yet. You can choose which of the packages to install, of course. The same

Callbacks seems to get GCed.
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

Re. When is *interactive* data visualization useful to use?
Hello Tal, You asked *When is it helpful to use interactive plots? Either for data exploration (for ourselves) and data presentation (for a "client")?* My answer: It's helpful for checking data quality, for exploration with and without "clients", for checking results, and for data presenting. Notes: (1) It's difficult to explain interactive data visualization in

about REPL and loops in general ...
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

Response to R across the university
This email isn't asking for assistance, but I thought R-help readers would find it interesting. This week we offered a half-day introduction to R for researchers at Augsburg University. The response was astonishing. Although Augsburg has no medical faculty and no engineers, there was far too much demand, with interest from every faculty (barring theology, "for one small
