similar to: Hook for running a function before evaluation

Hello, I have a question about addTaskCallback It is said that the argument visible allows to know wether the result of the top-level evaluation was printed or not. Nevertheless, in the following example, I encountered a problem, as it seems not all printed objects are visible... Could someone tell me where is the tip? TIA

Byron, I just read your blog (statcomp.blogspot.com, linked from your other post) and rand across your idea of an R/Flash graphics device. I've also been giving this some thought because of this amazing interactive flash app: http://tools.google.com/gapminder and others from http://www.gapminder.org/. I would love more than anything to work on this. The only hitch is that I'm so

Hi, Did anyone sucessfully install SJava package to R and was able to call R function from java in redhat linux8.0? I tried several days it still give me error either in libR.so or libjvm.so. for example, I can compile JavaRCall.java(a example with the SJava package) without problem. When I run it, it can connect to R and accomplish part of results, but fail for other calls. The outputs are:

R does provide the addTaskCallback / taskCallbackManager to run a callback function after every top level command. However there is not an equivalent interface that would be run _before_ each command, which would make it possible to time of top level calls and provide other execution measurements.

Hi , can some body tell to me "how to run a R method /function as a background process from R interface" Thanks K.Ravichandra [[alternative HTML version deleted]]

Hello, Following a discussion initiated on r-devel, that mentions SciViews-R and other GUIs issues for R, I would like to make comments (and would be happy if these comments would initiate interesting initiatives). A big, big problem with SciViews-R is that a part of it is written in Visual Basic 6, a M$$$$ language, not supported any more, buggy, non transposable to other platforms, etc,

Letting a user supply the autoprint function would be nice also. In a way you can already do that, using addTaskCallback(), but that doesn't let you suppress the standard autoprinting. Having the default autoprinting do its own style of method dispatch doesn't seem right. Bill Dunlap TIBCO Software wdunlap tibco.com On Tue, May 21, 2019 at 10:50 AM Lionel Henry <lionel at

Hi, this is Charlie. I have installed the Rpad on my server (using Fedora Core 6 with httpd2.24-2, mod_perl 2.0.2-6.1, perl 5.8.8 from RPM). When I access to the Rpad (through http://localhost/Rpad/basehtml), it shows me the main page as normal, however, problems occurs when I am testing the examples. It shows me a long message like: ----------------------------------------- #!/usr/bin/perl -w

Doing the same in R 2.9.2 gives clickable links in the browser. Furthermore, in both cases an empty graphics window
