This has been in the R-admin manual for a least a week, and I reported it here earlier than that. R 2.0.0 alpha does not allow f2c on 64-bit platforms. It's all been dealt with quite awhile ago ....

dear wizards: FYI: gentoo is a linux meta distribution, which compiles all packages. Once running, gentoo is stable on most applications. (it has some problems with system tools, such as grub.) the compiler is gcc 3.3.3. I do not expect anyone to track down for me why R fails on the gentoo amd64+gcc3.3.3 system, but I thought that it would be good to put it on the record to save

dear wizards: my .Rprofile has just one command for testing, loadhistory("~/.Rhistory") but this gives me an error on R startup: Error: couldn't find function "loadhistory" Invoking loadhistory() as the first interactive command works fine; incidentally, I believe loadhistory() in the .Rprofile worked in earlier or other platform R releases, too. Is the .Rprofile

Dear R Wizards: Running R 1.9.1. on amd64. Promise<- c(0,20,40); Expect<- c(0, 20, 0.2*20+.8*40 ); # this omits printing numbers on the axes labels. pdf(file = "bug.pdf" ); plot(Promise, Expect, type="b", ylim=c(0,60)); dev.off(); # this works postscript(file = "bug.eps" ); plot(Promise, Expect, type="b", ylim=c(0,60)); dev.off(); apologies if

hi: could someone please point me to a function that allows me to solve general non-linear functions? > irr.in <- function(r, c1, c2, c3 ) { return(c1+c2/(1+r) + c3/(1+r)^2); } > solve.nonlinear( irr.in, -100, 60, 70 ); 0.189 If someone has written an irr function, this would be helpful, too---though not difficult to write, either. thanks for any pointers. Regards, /iaw

dear R wizards: I would like to write a function that roughly places the equivalent of the following latex text into the current plot: \newcommand{ \placesigma }[4]{ \put(\#1,\#2){ \sigma_{A , #3} = #4 } I cannot figure out how to do this. I know I have to use a function that uses expressions in a text() invoke. But passing arguments and nesting strings and expressions has so far not

For me as a beginner a cookbook would be welcome. so many great code examples are posted into the help list, but finding these is quite difficult. I think it comes all down to the problem who is compiling / contributing and can judge what should go in. In this respect, Detlef Steuer (suggestion , might be a solution http://fawn.unibw-hamburg.de/cgi-bin/Rwiki.pl?RwikiHome. Frank >

SAS * better manuals. * tech support for most universities contracted into the price, thus for researchers. * batch orientation. if you have to handle data sets that are as large as your memory, SAS generally does it better. It seems to be an "n-pass design." Years ago, when memory was expensive, I could not use S/R even for simple problems. Just a few simple operations, and I

dear R community: i have been looking but failed to find the following: is there a function in R that updates a plain OLS lm() model with one additional observation, so that I can write a function that computes recursive residuals *quickly*? PS: (I looked at package strucchange, but if I am not mistaken, the recresid function there takes longer than iterating over the models fresh from

Dear R wizards: under R-2.1.0: eargs <- 3:5; line <- paste(c("echo A B", eargs)); cat("executing from R: '", line, "'\n"); system(line); Oddly, only "A" and "B" are echoed, not the eargs. I had hoped that line would be one string at this point, and for printing this seems to be true. However, unlist(line) still gives me the 4

hi: where would I find facilities to draw circles, ovals, and semicircles? (or should I construct them myself using curve?) regards, /ivo

I ran into an interesting oddity of R, if (0) { print(1); } else { print(2); } is a syntax error, while if (0) { print(1); } else { print(2); } or if (0) { print(1); } else { print(2); } is not. I presume it has to do with the duality of the newline functioning as an end of command (;) character, though it still seems a bit odd, and it took me a while to figure out

dear R wizards--- I would like to do some book-on-demand printing at a popular printer named lulu, but lulu requires inclusion even of the basic postscript fonts. Interestingly, my book itself does not need the 14 base acrobat fonts, only the embedded R figures do. Of course, I really would like to get pdftex to embed the fonts, but how to do this is not obvious either. [This method seems

Dear R help reader, I'm not an expert in R and are lerning a lot by reading the help digest, which is sometimes difficult because the huge amount of data posted. I have posted some questions before, and are impressed how quick I got a solution for my problem. Sometimes with quite different suggestions. I was always wondering if my questions didn't come up before. On the other site,

I am new to R. I want to graph group data using a "Traditional Bar Chart with Standard Error Bar", like the kind shown here: http://samiam.colorado.edu/~mcclella/ftep/twoGroups/twoGroupGraphs.html Is there a simple way to do this? So far, I have only figured out how to plot the bars using barplot. testdata <- scan(, list(group=0,xbar=0,se=0)) 400 0.36038 0.02154 200 0.35927
