Hello Using R Version 2.3.1 I have setup a cronjob to update packages, which worked successfully almost a year (it was called daily). Basically, it runs like this: Sys.getenv("http_proxy") update.packages(ask=F,repos="http://cran.r-project.org") (the http_proxy environment variable is set prior to the call). All of a sudden, I started to get this error: Error in

Hello Using R v. 2.3.1 which I installed recently, when I start it as root, there is nothing I can do. I get "Error: function xx not found" even when trying to leave R using q(). R works fine when started by an ordinary user. I rechecked the root environment several times and even have set it similar to that of an ordinary user (values of PATH etc.) but nothing helps. Using the command

Dear useRs, I'm trying to specify the colour of a factor with ggplot2. The example below gets me close to what I want, but it's missing a legend. Any ideas? Thanks, Thierry library(ggplot2) dataset <- data.frame(x = rnorm(40), y = runif(40), z = gl(4, 10, labels = LETTERS[1:4])) ggplot(data = dataset, aes(x = x, y = y, group = z)) + geom_point(colour = c("red",

Hi I have the following code which I would like to simplify. Id does linear regressions and returns the r-squares, and the coefficients. It runs slow, as it is doing the regressions for each - is it possible to get the values in a dataframe which looks as follow: expert | xx | seeds | r.squared | slope | intercept Thanks in advance, Rainer library(reshape) rsqs <- as.data.frame(

Dear useRs, Lately I noticed a strange warning in the summary of a lm-object. Any idea what this warning is about? I'm using R 2.5.1 on Win XP pro. > x <- rnorm(100) > y <- rnorm(100) > summary(lm(y~x)) Call: lm(formula = y ~ x) Residuals: Min 1Q Median 3Q Max -1,77809 -0,68438 -0,04409 0,63891 2,30863 Coefficients: Estimate Std.

Large for loops are slow. Try to avoid them using apply, sapply, etc. I've made the paste statements a lot shorter by using collapse. See ?paste for more info. Append.SQL <- function(x, channel){ sql="INSERT INTO logger (time, v1, v2, v3, v4, v5, v6, v7, v8, v9, v10) VALUES("d1=strptime(x[2],"%d/%m/%y %H:%M:%S %p '", d1, "' ,", paste(x[3:12],

Dear all, I found a discrepancy while performing a power calculation for a two sample t-test in R and S-PLUS, respectively. For given values of sample number (5 each), sd (0.2) , significance level (0.01), and a desired power (80%) I looked for the difference in means. These values differ: 0.5488882 in R and 0.4322771 in S-PLUS (see dump below). Did I overlook any detail or confuse some

Dear useRs, I'm struggling with the new version of ggplot2. In the previous version I did something like this. But now this yield an error (object "fill" not found). library(ggplot2) dummy <- data.frame(x = rep(1:10, 4), group = gl(4, 10)) dummy$y <- dummy$x * rnorm(4)[dummy$group] + 5 * rnorm(4)[dummy$group] dummy$min <- dummy$y - 5 dummy$max <- dummy$y + 5 ggplot(data

Dear useRs, Recently I've discorved ggplot2 and I must say that I really like it, although the documentation still is a working in progress. My first question: How can I change the position of the labels and the text of the labels? With a basic plot I would use axis(2, at = position.of.the.ticks, labels = text.at.the.ticks). Could someone provide me with an example of how to do this with

Hello My colleagues and I have recently established a large database (40 tables each with greater than 15 variables) in Microsoft's SQL Server 2000. Currently we are accessing this database via SQL client running an Windows XP. Our objectives are many fold including running SQL applications, outputting results to ARC/INFO IMS, production of summarizing tables - graphs and web interfaces for

Dear useRs, I'm trying to use ggplot2 in Sweave (R 2.5.1). The plots use the alpha channel, so I need to use pdf version 1.4. Search the mailinglist archive I found two solutions: \SweaveOpts{echo = FALSE, pdf.version=1.4} and explicit writing to a pdf 1.4 file. The latter works but the first doesn't. Probably I'm doing something wrong (see the Rnw file below). The file tmp_tmp.pdf is

Hello, I use newly R! I'd like to plot several data set together in one output window! How can I do that? Best regards Hadi --------------------------------- Never miss an email again! [[alternative HTML version deleted]]

Hi all, I am wondering if there is a function available in R for simulating spatial distribution of objects (plants in this case) in order to simulate sampling of a population . Specifically, I would like to be able to change the spatial correlation of individuals. I don't want to reinvent the wheel if it already exists. Thanks, Wade

I want to make a plot, but instead of showing _numerical_ values, I would like to show _symbolic_ values. For example, I want to plot a function y = a x + b, where x varies between Xmin and Xmax. I would like the plot to show, in the x-axis, the strings Xmin and Xmax, instead of their numeric values. Is it possible? Alberto Monteiro

Hi R-users I'm a beginner with R and statistics, so I need some help to start my data analysis. I've been reading some docs and tutorials on R and cluster analysis. I've got a large dataset (102000 points) with values of longitude, latitude and temperature and want to see if I can find groups (clusters). Following some tutorials I can look for principal components but get an error

Hello all-- I've been using 1.13 (v1915) on my Mac pretty intensly for about a month, but today when I tried to generate a plot I recieved this message: Error in quartz(width=9) : too many open devices I was caught by surprise, because I only had the R console open at the time. I checked to be sure, by clicking "Window" at the top bar, and R console was the only window open. I

I am trying to use apply and a list to supply names to a set of tables I want to generate. Below is an example that I hope mimics the larger original problem. EXAMPLE aa <- c( 2,2,1,1,2) bb <- c(5,6,6,7,4) aan <- c("yes", "no") bbn <- c("a", "b", "c", "d") mynames <- c("abby", "billy") mylist <-

Hi R, Please solve my problem........... I am extracting Bloomberg data from R, in a loop. R is getting fatigued by doing this process and gives some errors. I introduced sleep function. Doing this sometimes I get the results and sometimes not. I even noticed that if I give complete rest for R (don't open R window) for 1 day and then run my code with the sleep function, then the
