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

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

I just wrote a graphics device taking the X11 device in R-devel as a guide (I was told it's the reference device). It works perfectly with R-devel, but I just noticed that the API (e.g. the use of R_GE_gcontext) is incompatible with previous versions of R. Is the current API in R-devel set in stone or are there any further plans to change the API? (If so, how far?) Also, is there any

As Jason Turner told you, one possibility is to use the communication interface SJava (for another documentation, see this article: Urbanek, S. (2002) "No need to talk to strangers - Cooperation of Interactive Software with R as Moderator", http://simon.urbanek.info/simon/yawe/research/pub.html) but it seems not so easy to use (but if you want to do sophisticated things from what

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. However, after double clicking the R icon in the Applications folder, nothing appears to happen. The following message appears on the console: Mac OS X Version 10.3 (Build 7B85) 2003-12-11 08:45:31 -0500 prefs written dyld:

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

A while ago I compiled R 1.7.0 for AIX (with the above compiler - I'll call it xlc) and I was surprised that it went quite smoothly. Unfortunately with R 1.8.0 it's not as easy, but I succeeded at least partially. Static R works fine (after some tweaking), but --enable-R-shlib fails resp. produces a buggy R. Following are the problems I encountered (in a warning-to-fatal-error

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

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.

I'm trying to cross-compile R on a Mac OS X box to target Win32. It works quite well, everything works, except for one fortran file ppr.f in the stats package: ---------- Making package stats ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata making DLL ... i386-mingw32-g77 -O2 -Wall -c ppr.f -o ppr.o ppr.f:803: sorry, unimplemented: data

Madam, I've read your answer : /////////////////////////////////////// Here are other alternatives that are easy to implement and that you should consider depending on what you want to do: 1- one is to use R in batch mode ie you create a file in your java code with all the R commands and send it to R (via Process pc=Runtime.getRuntime().exec(Rcall); )and then R creates an

I re-generated configure of the latest R-devel with autoconf 2.57 and got the following problem: configure: error: conditional "HAVE_ORBIT" was never defined. Usually this means the macro was only invoked conditionally. (resolving HAVE_ORBIT leaves us with HAVE_GNORBA causing the same problem. You should be able to reproduce it by running autoreconf (or aclocal; autoconf - not just

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

Has there been a recent change in the behavior of binary operators? In SparseM it was, until quite recently ok to do scalar multiplication but now, > A*4 Error in A * 4 : non-numeric argument to binary operator > 4*A Error in 4 * A : non-numeric argument to binary operator > A%*%A An object of class "matrix.csr" Slot "ra": [1] 1 1 1 Slot "ja": [1] 1 2 3

Yes, lots of packages do use C/Fortran code ... it would be great if there were more packages that are "pure R" especially since the advent of S4 classes and namespaces. Is it worth suggesting that we create a designation "pure R" for packages that have no external source code and encourage more of these? Indeed, now the number of packages is so big could they be classified to

While playing around with panther I discovered (with surprise) that tcltk seems to work (even if not smoothly) with RAqua without first calling tkStartGUI. I switched back to 10.2.6 and it works as well. I think this is due to the "last minute" fix in RAqua now using idle timers because of too much cpu usage. Some "mouse" trick is needed though. If you want to test it you
