similar to: options(chmhelp = TRUE)

I cannot seem to get compiled help working with XP in neither 1.6 or 1.61. The ReadMe.rw1061 specifies: (ii) Compiled HTML files. Set this as the default by options(chmhelp=TRUE) or for individual help items by help(topic, chmhelp=TRUE). Full text search is available from the Search tab. According to Microsoft, to make use of this you will need to have IE3 or later installed and a recent version

For the following code below, the x-axis ticks are 1,2,3,4,5,6,7 when I was expection them to be 1,2,8,9,10,11,12. Please help me figure out where is the mistake. library(lattice) testdata <- as.data.frame(t(structure(c( 1,2005,9.24,6.18,634, 2,2005,8.65,6.05,96, 8,2004,6.81,6.51,16, 9,2004,9.0,7.29,8, 10,2004,8.84,6.18,524, 11,2004,8.54,6.35,579, 12,2004,9.97,6.3,614, 12,2005,8.75,5.84,32,

Hi When I use plot(hclust(dist..)...)...) etc to create a dendrogram of a hierarchial cluster analysis, I end up with a vertical tree. What do I need to do to get a horizontal tree? Also, my users are used to seeing trees who's leaves all "end" at the same place (eg. Like in minitab). Is this possible in R? Thanks Mick Michael Watson Head of Informatics Institute for Animal

Dear useRs, I'd like to produce some scatter plots where N units on the X axis are equal to N units on the Y axis (as measured with a ruler, on screen or paper). This approach x <- sample(10:200,40) ; y <- sample(20:100,40) windows(width=max(x),height=max(y)) plot(x,y) is better than plot(x,y) but doesn't solve the problem because of the other parameters (margins etc). Is

Hi all, Say I have a matrix A with dimension m x 2 and matrix B with dimension n x 2. I would like to find the row in A that is closest to the each row in B. Here's an example (using a loop): set.seed(1) A <- matrix(runif(12), 6, 2) # 6 x 2 B <- matrix(runif(6), 3, 2) # 3 x 2 m <- vector("numeric", nrow(B)) for(j in 1:nrow(B)) { d <- (A[, 1] - B[j, 1])^2 + (A[,

Hello, as I just spent a (too long) while searching for a way how to persistantly switch back the help display routines from chm to text, here a small documentation how to do that with the windows version of R. The windows installer asks which help type you want to use, I wanted to test the chm version -- which I didn't like. If you after installation want to switch back, you have to edit

I just noticed the following in update.formula and I'm wondering if this behavior is the intention of the developers. Here's an example: update(`a: b` ~ x, ~ . + y) Note now that the response has no backticks and is interpreted as a:b (i.e. ":" is now an operator). This is because in update.formula the call to terms.formula uses simplify = TRUE. I'm working with data that

Hi, All, I'm writing a wrapper for stop that produces a popup window using tcltk. Something like: error <- function(...) { msg <- paste(..., sep = "") if(!length(msg)) msg <- "" if(require(tcltk, quiet = TRUE)) { tt <- tktoplevel() tkwm.title(tt, "Error") tkmsg <- tktext(tt, bg = "white") tkinsert(tkmsg,

Hello, i know that i have to use optim, but i'm confused how its possible maximize the sum over all l[i] and get the optimized max(LL), r and alpha? LL <- function(trans,time){ for(i in 1:length(trans){ l[i] <- log(lgamma(r+trans[i] - gamma(r+1)*(alpha/alpha+t[i]))**r)*(t[i]/alpha+t[i]))**trans[i] } return(sum(l)) } i'm confused how i have to set r and alpha and i

Hi, all, I'm looking a utility for removing a directory from within R. Currently, I'm using: foo <- function(...) { mydir <- tempdir() dir.create(mydir, showWarnings = FALSE, recursive = TRUE) on.exit(system(sprintf("rm -rf %s", mydir))) ## do some stuff in "mydir" invisible() } However, this is assumes "rm" is available.

Hi all, I have a data.frame with the following colnames pattern: x1 y11 x2 y21 y22 y23 x3 y31 y32 ... I.e. I have an x followed by a few y's. What I would like to do is turn this wide format into a tall format with two columns: "x", "y". The structure is that xi needs to be associated with yij (e.g. x1 should next to y11 and y12, x2 should be next to y21, y22, and
