I downloaded the free CD's and installed Suse 10.0. When I tried to install the latest RPM for R, the Yast installer complained that two files were missing. I was told that I can install from the internet, and started the process, but found I must supply the name of the server and the name of the directory. I tried several combinations unsuccessfully. Can anyone help me?

I have downloaded the source code for Linux. the ./configure procedure can find gcc but cannot find f77 or f2c I have looked for the above compiler with Test and installed all what pertains to Fortran. Still not even the man pages for f77 anf fc2 work >. Where is f77 and f2c with linux 10.3 ?? Thank you do much -- Maura E.M [[alternative HTML version deleted]]

I have installed Simple Sudoku (http://www.angusj.com/sudoku/index.php) but I cannot minimise it, nor go to another screen to do something else. If I try, its window gets larger, vertically. I am using wine 20050725 (which is what is packaged for my system at present), on a Debian system running XFree86, with icewm-gnome. Can anyone advise why this program "hogs attention"? -- Phil

Dear All I am doing the following: > x <- yacas("3/2") > for (i in 2:400) + x <- yacas(paste(x,"*",x)) > x expression(Inf^1.260864167e+117/Inf^6.304320836e+116) > Eval(x) [1] NaN No luck this way. However, I am successful with > y <- yacas("(3/2)^400") > y expression(7.05507910865533e+190/2.58224987808691e+120) > Eval(y) [1]

Hello I am trying to install the R RPM for Suse 10.0 on an x86_64 PC.

Hi, I am writing a function which requires user to enter a single character. Something like: hello<-function(){ input<-scan(n=1,what="a") if(input=="h")cat("Hello") # What goes after the 'if' is completely arbitrary, for simplicity sake I simply put a cat command here. } I want R to automatically finish scanning after the user has entered the 1st

Hi Folks, I'm relatively new to r. I'd like to have a user respond by pressing a 1 or a 2 and determining their choice and the time of response. Previous postings have indicated that keyboard responses can be processed using scan and readline but both seem to wait for the user to also press return. Is there a way to detect the initial key press without requiring them to hit return?

Team, I am trying to learn a GUI for Ruby and I picked wxRuby. The problem is that I am kind of slow learning this and I now feel frustrated after trying for about at least 7 hours. I am trying to design a simple Sudoku 9x9 grid to display numbers, 1 - 9, using buttons. I posted a question on Ruby forum ruby-talk and a gentleman, Alex Fenton, answered my questions. Alex gave me what appear to be

Hi everybody - this is an oddball question. I wonder if anybody has programmed any games in R, such as Sudoku, Tic-Tac-Toe and the like. Or even a flight simulator... R mateys! Let's make some t-tests! Regards, David

I have started with using R on Windows, and I am really happy about the system. Now, one of my other ambitions is to learn how to use Linux, so yesterday I downloaded OpenSuse and installed that. The next problem was to try to use R with Linux. And there I met the wall. I've understood that RPM's are somewhat like installing programs on Windows, so that was downloaded and started

as.character.factor contains this line (where cx=levels(x)[x]): if ("NA" %in% levels(x)) cx[is.na(x)] <- "<NA>" Is it possible that this is no longer the desired behavior? These two results don't seem very consistent: > as.character(as.factor(c("AB", "CD", NA))) [1] "AB" "CD" NA > is.na(.Last.value)[3] [1] TRUE

The following code produces 6 plots on a page, but the first is distorted and different from the others: par(mfrow=c(3,2), las=2) for (i in 1:6) { frame() par(mar=c(7, 7, 1, 1)) axis(2); box(); abline(h=seq(0,1,.5), col=2:4) } The first plot's axes are mis-aligned with the plotting area implied by the box. It seems to be a result of calling par(mar) after frame(). Is this expected

Thanks to David Meyer [david.meyer@ci.tuwien.ac.at] and David Brahm [brahm@alum.mit.edu] who suggested: m[ cbind(index.i, index.j) ] <- vals This works fine for the example I gave. Unfortunately, this approach doesn't extend to using the row and column names to make assignments: > m <- matrix("",ncol=3,nrow=3) > dimnames(m) <-

R> x <- 0. + 1:8000 R> y <- outer(-x, x, pmin) Error: cannot allocate vector of size 1000000 Kb Why does R need to allocate a gigabyte to create an 8000 x 8000 matrix?

After upgrading to R-2.3.1 on Linux Redhat, I was suprised by this: R> x <- c(721.077, 592.291, 372.208, 381.182) R> sum(x) - 2066.758 [1] 4.547474e-13 Now I understand that floating point arithmetic is not precise, but 1) the result is exactly 0 in R-2.2.1 (patched) on the same machine, 2) .Machine$double.eps = 2.2e-16, so the error seems quite large. Also note I get the same

I have been curious about rSpec for a while, so I thought I''d give it a try... I started reading Ron Jeffries'' articles on Sudoku (http://www.xprogramming.com/xpmag/OkSudoku.htm), and noticed he was doing TDD, I thought, this would be fun to do with BDD... Can you comment on the following? (note that I added a method in the Game class called cells which return @cells) to make

I sent a message to <r-announce at stat.math.ethz.ch> last Thursday ("New package: colSums"), and still haven't seen it echoed on r-help or on the web archive (in fact there is no r-announce web archive for 2002). Is something broken? Did I need to use <r-announce at lists.R-project.org> instead? -- -- David Brahm (brahm at alum.mit.edu)

I want to use R to run a reaction-time experiment: Something appears on the screen, I respond by typing something (one keystroke), the system measures the speed of my response. R would be great for this if only I didn't have to hit Enter to enter that keystroke. I am doing such experiments now but they require two actions per trial: hit keystroke, hit Enter. Is there some way that R can be
