Dear List, I need to add a subscript and a superscript to some of the ions in the labels on some plots. I have got to here but now I'm stuck: plot(1:10, xlab = expression(paste("nm SO"[4], " ", mu, "eq cm"^{-2}, " yr"^{-1}))) Which gives almost what I require. No matter what I tried, however, I could not get bot a sub script *and* a superscript

Dear List, I have the following function: coca <- function(x, ...) { if(is.null(class(x))) class(x) <- data.class(x) UseMethod("coca", x) } and a default method coca.default <- function(x, y, method = c("predictive", "symmetric"), reg.method = c("simpls", "eigen"), weights = NULL,

Dear list, given this formula: > fmla <- formula(y1 ~ spp1 + spp2 + spp3 + spp5) > fmla[[3]] spp1 + spp2 + spp3 + spp5 is this the intended behaviour of as.character: > as.character(fmla[[3]]) [1] "+" "spp1 + spp2 + spp3" "spp5" ? Where does the extra "+" come from? > as.character(fmla) [1] "~"

##data y1 <- matrix(c(3,1,0,1,0,1,1,0,0,0,1,0,0,0,1,1,0,1,1,1), nrow = 5, byrow = TRUE) y2 <- matrix(c (3,0,10,3,3,0,0,1,1,0,0,0,0,0,1,0,1,0,0,2,1,0,1,1,0,2,1,1,4,1), nrow = 5, byrow = TRUE) y1 <- as.data.frame(y1) y2 <- as.data.frame(y2) rownames(y1) <- rownames(y2) <- paste("site", 1:5, sep = "") colnames(y1) <-

Dear List, I have the following problem with axis.Date, here is an artificial example: dates <- scan(what = "character") "25/03/2000" "26/03/2000" "27/03/2000" "28/03/2000" "29/03/2000" "30/03/2000" "31/03/2000" "01/04/2000" "02/04/2000" "03/04/2000" "04/04/2000"

Dear List, I often have to merge two or more data frames containing unique row names but with some columns (names) common to the two data frames and some columns not common. This toy example will explain the kind of setup I am talking about: mat1 <- as.data.frame(matrix(rnorm(20), nrow = 5)) mat2 <- as.data.frame(matrix(rnorm(20), nrow = 4)) rownames(mat1) <- paste("site",

Dear list, I am using Sweave to build a small report. I want to produce a series of figures, each figure containing a number of plots and then have them included in the Sweave file. An example would be to : postscript(file = "ANCbwplot%03d.eps", onefile = FALSE, other options...) oldpar <- par(mfrow = c(2,2)) .... do lots of plots to produce a number of eps files .... par(oldpar)

Hi, I noticed the following problem with xy.coords() in R 2.2.1-patched (version info at the foot of this email) and R 2.3.0 unstable (subversion no: r37123): > xy.coords(x = matrix(1:20, ncol = 2)) Error in xy.coords(x = matrix(1:20, ncol = 2)) : argument "y" is missing, with no default > xy.coords(x = matrix(1:20, ncol = 2), y = NULL) $x [1] 1 2 3 4 5 6 7 8 9

Hi I'm having a problem with model.frame, encapsulated in this example: y1 <- matrix(c(3,1,0,1,0,1,1,0,0,0,1,0,0,0,1,1,0,1,1,1), nrow = 5, byrow = TRUE) y1 <- as.data.frame(y1) rownames(y1) <- paste("site", 1:5, sep = "") colnames(y1) <- paste("spp", 1:4, sep = "") y1 model.frame(~ y1) Error in model.frame(formula, rownames,

Dear List, My colleague has been having a problem with the following data and plotting commands. The example below is part of a larger set of plots, but I've isolated the problem to this example using this small dataset (below), which kills rgui consistently. My version info > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status

Hi, I have a bit of a problem with a legend in png, eps and pdf plots produced from a custom plotting function. I was writing a little function to produce some stock plots for a routine analysis conducted in our lab. I have a wrapper function figures() (see below) that produces eps, png and pdf versions of the lab output. When I draw the plot on the X11() device the correct amount of space is

Hi, Following the Writing R Extensions manual, I created a method for the cor function. As cor is not a generic, I followed the advice of section 6.1 of the same manual and did the following: cor <- function(x, ...) UseMethod("cor") cor.default <- stats::cor cor.symcoca <- function{ some code } I used package.skeleton to create the basic set-up of my package, containing the

Dear List, I have a 47 species * 83 samples matrix containing percentage abundance data. I have two cluster analyses one of the samples and one of the species, and have ordered the rows and columns of the species by samples matrix according to these two cluster analyses. So far so good! Now what I want to do is create a plot with the species dendrogram at the top of the plot, the samples

Dear list, I just hit an error that stopped my make && make check-devel operation on my linux box (FC3, i686 P4 2GB RAM). Just to note that I've been building the development branch(?) for some time and this is the first hint of a problem. 1) updated the src tree using svn update 2) ran ../configure --with-recommended-package=no from my build directory 3) got: R is now configured

Hi I am having a particular problem with some glm models I am running. I have been adapting code from Bill Venables 'Programmers niche' in RNews Vol 2/2 to fit ca. 1000 glm models to a combination of species 0/1 data (as Y) and related physicochemical data (X), to automate the process of fitting this many models. I have successfully managed to fit all the models and have stored the

Hi, I've had a look the bug list and searched though the R documentation, email lists etc. but didn't see anything on this: when I do: summary(species.glm1, correlation = TRUE) I get a correlation matrix like this: Correlation of Coefficients: ( p I(H C pH * 1 I(pH^2) * B 1 Ca . . 1 I(Ca^2) . . B attr(,"legend") [1] 0 ` ' 0.3 `.'

Dear list, I have been using and testing the alpha/betas of R 2.4.0, sources for which I got from svn.r-project.org/R/branches/R-2-4-branch, and which I compiled on my Fedora Core 5 machine. No problems there. I have just updated the source tree today and re-compiled - which also works just fine. When run, this gives: R version 2.4.0 Patched (2006-10-03 r39576) So I assume from that, that I am

Dear List, I'm using Sweave to produce a series of class handouts for a course I am running. The students in previous years have commented about wanting output within the handouts so they can see what to expect the output to look like. So Sweave is a godsend for producing this type of handout - with one exception: Is there a way to suppress some rows of printed output so as to save space

Hi, On a new Dell laptop, with a fresh FC3 installation (with latest updates applied) I am experiencing make hanging consistently after/during building grDevices. This happens when using the configure flag --with-lapack (I have the LAPACK rpm distributed with FC3 installed). The last two lines of output are: make[5]: Leaving directory

Dear list, Following advice posted to this list a while back by Prof Ripley [1], I have been trying to draw a per mille character [2] in an axis label. This should give the correct character: plot(1:10, ylab = "\u2030") but all I get is '"S'. I'm running linux (FC5) and have fonts installed that have the correct character (viewed in the Gnome character map at least).
