I downloaded and installed R-1.3.1 yesterday, and had to change line 2 of the "packages.html" file in $RHOME/doc/html/ The configuration steps were "the usual", tar zxvf ... cd ... ./configure make make check make install If it's relevant, Sys.info() sysname release "Linux" "2.2.14"

Thanks to Rolph Turner and Jason Turner ... I guess I was too excited about getting back on the list after an absense of several years ... I'll be a little more thoughtful about the problem before posting next time, and a little less trigger-happy with the "Send" e-mail button. Never-the-less, much appreciated. - Mohamed -----Original Message----- From: Rolf Turner

Sorry for the off-topic question, but I know there are some talented LaTeX users out there. Which bibliography style gives only the year in text citations (e.g "for further details, see Anderson (1992)" )?

Dear List, creating factors in a given non-default orders is notoriously difficult to explain in a course. Students love the ifelse construct given below most, but I remember some comment from Martin M?chler (?) that ifelse should be banned from courses. Any better idea? Not necessarily short, easy to remember is important. Dieter data = c(1,7,10,50,70) levs =

Dear all, Our department uses the linux system and we are not allowed to submit job directly. We must make a batch to submit through "qmon". so, I make a foo.sh file, which only contains one line: nohup R --vanilla < foo.txt > foo.results foo is all my codes. It is a simulation of 200 times. I set the seed at the beginning. It is to estimate the success probability, which is

My question is: is there a way for Rtangle() to *not* print re-used code chunks? It'd be easy enough to brew up a perl script to do just this, but if methods exist already, I'd rather use them. My reading of the help pages and FAQs has missed something, if it's there. Background: I have course notes on R, written using Sweave. I want to provide the R code separately so the

Probably doing something wrong here. I'm getting an empty file called "Rplot.ps" when I do this: > foo<-rnorm(100) > postscript() > boxplot(foo) System info: Version: platform = i586-pc-linux-gnu arch = i586 os = linux-gnu system = i586, linux-gnu status = major = 1 minor = 2.2 year = 2001 month = 02 day = 26 language = R Search Path: .GlobalEnv,

Lattice experts: Can you think of a way to produce a levelplot as below and then add a histogram of the z variable to the top margin of the plot that would sit on top of the color key? x <- seq(pi/4, 5 * pi, length.out = 100) y <- seq(pi/4, 5 * pi, length.out = 100) r <- as.vector(sqrt(outer(x^2, y^2, "+"))) grid <- expand.grid(x=x, y=y) grid$z <- cos(r^2) *

I am new to using S4 methods and have run into this problem (on Windows XP using R 2.4.1): I am writing a package in which I use the graph package. I define my own classes of graphs as: setOldClass("graphsh") setOldClass("ugsh") setIs("ugsh", "graphsh") (I know that I "should have" used setClass instead - and I will eventually - but right now

Given the example: R> (levs <- quantile(volcano,c(0,0.1,0.5,0.9,0.99,1))) 0% 10% 50% 90% 99% 100% 94 100 124 170 189 195 R> levelplot(volcano,at=levs) How can I make the key categorical with the size of the divisions equally spaced in the key? E.g., five equal size rectangles with labels at levs c(100,124,170,189,195)? Apologies if this is obvious. -A R> version

For ordered factor the natural contrast coding would be to parametrize by the succsessive differences between levels, which does not assume equal spacing of factor levels as does the polynomial contrasts (implicitly at least). This requires the contr.cum, which could be: contr.cum <- function (n, contrasts = TRUE) { if (is.numeric(n) && length(n) == 1) levs <- 1:n

Dear R-devel list members, I'd like to suggest a more flexible procedure for generating contrast names. I apologise for a relatively long message -- I want my proposal to be clear. I've never liked the current approach. For example, the names generated by contr.treatment paste factor to level names with no separation between the two; contr.sum simply numbers contrasts (I recall an

Found one that stumped me. I did a search on R-bugs for the string "d-p-q-r-tests", and found zero entries in all categories (I don't think I secretly gave it a regex). Did the usual configure, make, make check on OpenBSD 3.0, and encountered this message on d-p-q-r-tests.Rout: running code in `d-p-q-r-tests.R' ... OK comparing `d-p-q-r-tests.Rout' to

I am trying once again. By just changing f <- match(xlevs[f], nlevs) to f <- match(xlevs, nlevs)[f] , function 'factor' in R devel could be made more consistent and back-compatible. Why not picking it? -------------------------------------------- On Sat, 25/11/17, Suharto Anggono Suharto Anggono <suharto_anggono at yahoo.com> wrote: Subject: Re: [Rd] Function

In R devel, function 'factor' has been changed, allowing and merging duplicated 'labels'. Issue 1: Handling of specified 'labels' without duplicates is slower than before. Example: x <- rep(1:26, 40000) system.time(factor(x, levels=1:26, labels=letters)) Function 'factor' is already rather slow because of conversion to character. Please don't add slowdown.
