similar to: loadhistory() in .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

History files saved using nFile Save History do not open when using File Load History. I notice that when they are saved they do not seem to have a file extension and there is no option to chose an extension. Is this a problem. Other than this it seems so simple that I can't see what the problem is. I've tried using loadhistory and savehistory with the same problems. The syntax guide

Dear R-Helpers, I'm fiddling with my .Rprofile in Windows XP & R 2.7.0 Beta. I prefer to manually save my workspace but automatically save my command history via the .Rprofile. That is working fine once I found that "utils::" was required before the loadhistory & savehistory functions. What I would like to do is add a separator line with a date between the histories of each

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

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: 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

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

I think I've said it before, but I think such a book ought to coauthor Paul Johnson, whether or not he does any work beyond the Rtips web pages. A few of the tips may need a bit of

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

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 wizards: an operation I execute often is the deletion of all observations (in a matrix or data set) that have at least one NA. (I now need this operation for kde2d, because its internal quantile call complains; could this be considered a buglet?) usually, my data sets are small enough for speed not to matter, and there I do not care whether my method is pretty inefficient (ok, I

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

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),

NOTE: WinXP, R2.2.0 All, a while back I posted a question about using relative filereferencing.
