...or what I need. I haven't gotten into the sql thing yet. Most recently I've been trying to install the new package ff (not yet on the CRAN repository). I can't find emails of the folks developing ff, so I was hoping someone here might have an idea how to deal with this. >From http://wsopuppenkiste.wiso.uni-goettingen.de/ff/ I've downloaded the ff_1.0.tar.gz. > install.packages(pkgs="ff_1.0.tar.gz",repos=NULL,destdir="/temp",type="source") <much output omitted> g++-4.0: installation problem, cannot exec 'i686-apple-darwin8-g++-4.0.0': No su...

...own configuration, and has decided to use gcc. That would probably work, except that it is mixing up the Sun C++ compiler (CC) with the Gnu command line options (-Wall -pedantic -fno-exceptions .....) AND the Sun command line options (-xO4 -xlibmil -dalign). All my attempts to follow the http://wsopuppenkiste.wiso.uni-goettingen.de/~dadler/rgl link on the rgl catalogue card at CRAN have failed. - Did I do something wrong? - What if anything can I do about it?

Does anyone have any suggestions on perspective plotting of piecewise constant functions? Ideally, I would like something like plot.stepfun for functions that are piecewise constant on polygons. Even pointers to non-R strategies would be welcome at this stage. url: www.econ.uiuc.edu Roger Koenker Dept. of Economics UCL, email rkoenker at uiuc.edu Department of Economics Drayton House, vox:

Hello, I am trying to compare two histograms using barplot. the idea is to plot the histograms as pairs of columns side by side for each x value. I was able to do it using barplot before but I can't remember now for the life of me now how I did it in the past: > d [,1] [,2] -37.5 0.0000000000 2.789396e-05 -32.5 0.0001394700 5.578801e-05 -27.5 0.0019804742

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

Hello, I am dealing with numeric vectors 10^5 to 10^6 elements long. The values are sorted (with duplicates) in the vector (v). I am obtaining the length of vectors such as (v < c) or (v > c1 & v < c2), where c, c1, c2 are some scalar variables. What is the most efficient way to do this? I am using sum(v < c) since TRUE's are 1's and FALSE's are 0's. This

I have found XLispStat's spinning plots illuminating. I'd like to do the same thing in R. A dozen or so probes with help, help.search, apropos haven't turned up anything, and I've even resorted to grepping through the entire R source distribution looking for 'spin.*plot', to no avail. Either the feature is called something else in R (what?), or it's in some other

Dear all, Is there a camera rotation for 3d graphics in R. I have seen it in a conference one time and thought it is pretty neat. the presenter was able to rotate the 3d graph with dragging the mouse up down left right. If not in R is there something that is open source that does this. Thank you Jean Eid

Hi, I'm new to R (and math ;) Would somebody please be so kind as to direct me in plotting a 3D sphere? I tried something in the lines of: #### y <- x <- seq(-pi, pi, length=pi*10) f <- function(x,y) { z <- sqrt(pi - x^2 - y^2) #z[is.na(z)] <- 0 z } z <- outer(x, y, f) persp(x, y, z, theta = 120, phi = 30) #### I've also tried: .... make.surface.grid(...) ..
