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

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 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

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

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
