we still do not have dynamic graphics in R natively. i just found out about a widget library called fltk info is at www.fltk.org it has all the stuff r currently can do only through tcl/tk or (as i do it) excel: sliders, knobs, spinners and so on. it is multiplatform, there are production versions for unixen and windows, and there is a beta for macs. this could be a way of getting some of

Hello. I was wondering how one can find the exact values of the range of an axis within a plot. In xlispstat it was (send plot :range 0). Thanks much, Jason

Dear R users, I was trying to install the package RXLisp by Duncan Temple Lang on a MDK 9.1 Linux machine running R 1.8.0 installed from a RPM. Unfortunately I had a problem loading the shared library into R. Since I'm a Linux newbie I was not able to solve the problem. Maybe some of you can help me. First of all I downloaded the source archive for Xlisp-Stat and for the RXlisp package.

I am sorry for this off-topic question. Just curious how xlispstat is used in the industry and what's it strengthen compared with other computing languages such as R or matlab? Thanks a lot. [[alternative HTML version deleted]]

Has anyone experimented with the Network Common Data Format (netcdf) described at http://www.unidata.ucar.edu/packages/netcdf for archiving data? Is this format widely used outside of atmospheric research? -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info",

Here is the summary on predict when using an arima0 object: The arima0 object must be based on a time series vector. That is; x <- ts(xm1, frequency=12, start=c(1975,1)) x.ar <- arima0(x,order=c(1,1,1)) predict(x.ar,n.ahead=3) Thanks so much to Prof. Brian Ripley and David Brahm and other! Sincerely, Erin Hodgess

A student is trying to cluster some data. Tree-building things seem to be pretty hopeless (we've tried most of the ones in R, I think). Multi-dimensional scaling produces somewhat tantalising results: things do clump together somewhat, but the clusters overlap a lot. I was wondering if these was an artefact of squeezing it down to 2D, and whether 3D might be better. So loc <-

Hello. Sorry for the elementary post. I've looked through the documentation, but can't seem to find a function which allows one to extract the position of an element within a list...for example the position of the element 4 in the vector c(1,2,4,3,6) is 3. Thanks much for any help. Jason

Hi All, I've done some work recently making some of our image analysis library callable from R and Splus. Most of the C image functions use an abstract data type, and R only sees a pointer to this. All memory allocation is done by the library. This leads to some interesting problems. I'm interested in your views about possible solutions. 1) assignment. something like a<-b, where a and

Hi, My collector supports only base pointers as stack roots. This wasn't a problem until I tried to run some optimizations before RS4GC, which introduced (interior) derived pointers. The statepoint documentation mentions that these collectors exist, but doesn't mention whether and how this is currently supported. What could I do to make it work? -Manuel

John Fox (see below) raises important questions for the Lisp-stat community (and perhaps the R community) to consider. This message thread was not cross-posted to r-devel@lists.r-project.org, so I do so now. I have never been an active or particularly adept Lisp-stat programmer. But I have worked on or used several projects for which Lisp-stat seemed the ideal environment-- for implementing

We have a few questions about the current state of GC. We decided to start (and finish?) our work by finishing SemiSpace. process_pointer is meant to move objects from CurSpace to OtherSpace. How can it find pointers to a moved object? How does it know the size of each object? Assuming we are writing a GC that will only work from llvm assembly our best option seems to be forcing the assembly code

This is entirely up to you, as you're basically implementing the semispace

Is it possible to run R soley from the shell? I'm evaluating necessary fixes to R and XLispStat (and eventually SAS and S-PLUS 4) for running as subprocesses to Emacs (NTEmacs) for ESS. Currently, I lose control of R when running via Emacs; is it possible to "remove" the windows? (all, or all but the graphics window)? best, -- -tony (Anthony Rossini) Statistics

Hello. In messing around with some of the graphical parameters using the par() function (setting margins for example), I've noticed that the plot doesn't always immediately respond to changes...for example when lines are added, if they are out of the range you need to physically find out what the new max range has to be. Is there a companion function in R to the xlispstat function
