Full_Name: Sundar Dorai-Raj Version: 2.8.0 OS: Windows Submission from: (NULL) (76.220.41.126) The following code crashes R: library(tcltk) tt <- tktoplevel() tc <- tkcanvas(tt, yscrollcommand = function(...) tkset(ts, ...)) > sessionInfo() R version 2.8.0 (2008-10-20) i386-pc-mingw32 locale: LC_COLLATE=English_United States.1252;LC_CTYPE=English_United

Hi, all, (sessionInfo at the end) I've been struggling with the tcltk package and can't seem to get the ttkcombobox to work. Here's an example: library(tcltk) p <- tktoplevel() l <- tclVar() ## I don't know if I'm even calling it correctly cb <- ttkcombobox(p, values = letters[1:4], textvariable = l) tkpack(cb) 1. How do I know when the value of the combobox has

I've just encountered a segfault when using DierckxSpline::percur function. Below is the minimal example which triggers the error: --- library(DierckxSpline) x <- 1:10 y <- rep(0, 10) pspline <- percur(x, y) --- *** caught segfault *** address (nil), cause 'memory not mapped' Traceback: 1: .Fortran("percur", iopt = as.integer(iopt), m = as.integer(m), x =

Hi, all, I just recently upgraded my computer though I'm using the same OS (XP). But now I'm having difficulty building packages and I cannot seem to solve the problem. I'm using R-2.1.1pat on Windows XP. Here is what I tried: D:\Users\sundard\slib\sundar\R>R CMD CHECK sundar * checking for working latex ... OK * using log directory

I'm new to lattice and can't figure out what the problem is with the following example: ######################### > library(lattice) Loading required package: grid Attaching package `lattice': The following object(s) are masked _by_ .GlobalEnv : xyplot The following object(s) are masked from package:base : levels > test.data <- data.frame(x=rnorm(100), +

Hi all, Here's a curosity I ran into since upgrading to 1.6.2 (precompiled for Windows). When using the chm help I get the following warning. I saw a recent post regarding this as a new warning (``dyn.load warning message in R1.6.2 on Windows XP'' dated 1/28/03), but not in the context of the help system. The warning only appears once and does not prevent the chm file from

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[,

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,

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. I know of

Hi, all, I just recently noticed a change in terms.formula from 2.2.1 to 2.3.1 (possibly 2.3.0, but I didn't check). Here's the problem: ## 2.2.1 > update(~ x | y, z ~ .) z ~ x | y ## 2.3.1 > update(~ x | y, z ~ .) z ~ (x | y) and in the NEWS for 2.3.1 o terms.formula needed to add parentheses to formulae with terms containing '|'. (PR#8462) So, there must be

Hi all, I have a question that I don't have a good answer for (note the word "good"; I have an answer, but I consider it not "good"). Take the following data in a single tab-delimited text file: <text> A Labels Value SE 2.5% 97.5% R90 0.231787 1.148044 0.035074 1.531779 R0 0.500861 0.604406 0.185336 1.353552 B Labels Value SE 2.5% 97.5% (Intercept) 1.367514

Hi, I'm wondering if someone has solved the problem of converting very large integers to hex. I know about format.hexmode and as.hexmode, but these rely on integers. The numbers I'm working with are overflowing and losing precision. Here's an example: x <- "6595137340052185552" # stored as character as.integer(x) # warning about inaccurate conversion

Hi All: This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess. See if it got corrected now (I do not have

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
