...r, the lm model seems to support higher order polynomials, e.g.: > lm(dist ~ speed + I(speed^2)+I(speed^3), cars) Is there some sense in which that model is "linear", or is R's lm() providing extra functionality?

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

...A, or must the independent variables be quantitative in nature? If the answer is that it can be done, and that it can be done with anova/aov, how do I go about expressing the "data model" for qualitative factors?

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 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

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.

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 R wizards: is it possible to use a postscript font symbol as a plot symbol? in particular, I want to use the four postscript symbols for playing cards (club, heart, spade, diamond) as points. In LaTeX, these four are \Pisymbol{psy}{"A7} \Pisymbol{psy}{"A8} \Pisymbol{psy}{"A9} \Pisymbol{psy}{"A10} and what I would love to do is place them, at say, (x=1,y=1),

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
