Hello dear R-help mailing list, The other day I published a blog post (with some R code) to help R-users who want to implement a simpler upgrading strategy for R (under windows - but probably the same will be true of mac OS, I am not sure about Linux). This e-mail has 3 goals: (a) To share, (b) to get feedback, and (c) to propose to implement this strategy to R's core. * * *a) Share* The

I'm surprised this isn't a FAQ, but I searched all over and could not find a reference to it. Chambers (1998) makes repeated references to "Chapters" in S (e.g., p. 6), but I can find no reference to "Chapters" in R. Since Chapters were not used in earlier versions of S, I'm wondering if R uses them or not. If it does, how does one get them to work? I've

Hi, I am trying to read a tab-delimited file that has trailing tab delimiters. It's a simple file with two legitimate fields. I'm using the first as row.names, and the second should be the only column in the resulting data frame. Initially, R was filling the last column with NA's, but I was able to stop that by setting

Hi, I can't get the colClasses option to work in the readHTMLTable function of the XML package. Here's a code fragment: require("XML") doc <- "http://www.nber.org/cycles/cyclesmain.html" table <- getNodeSet(htmlParse(doc),"//table") [[2]] # The main table is the second one because it's embedded in the page table. xt

Hi, I've been struggling with this problem the last few days and finally discovered it's happening at a very fundamental level. Going through Stephen Turner's tutorial on ggplot2, I entered these base graphics commands: > with(diamonds, plot(carat,price)) > with(diamonds, plot(carat,price), xlab="Weight in Carats", ylab="Price in USD",

Hello, I have a function with these lines: test <- function(object,...){ cat("object: has ",nrow(object),"labels\n") cat("Head:\n") head(object,...) cat("\nTail:\n") tail(object,...) } If I feed it a data frame object, it only prints out the tail part. If I comment out the last two lines of

Hi R fans, As a newbie following the five-hour rule (after hitting my head against the wall for five hours, post to this list), I am appealing for some help understanding geom_rect() in ggplot2. What I want to do is very simple. I want to generate a plot of rectangles. Each one represents a business cycle. The x-values will be pairs representing the start and end of each cycle. The y-values

Hi, I have a bright, diligent second-year graduate student who wants to learn statistics and R and will, in effect, be taking a tutorial from me on these subjects. (If you've seen some of my questions on this list, please don't laugh.) As an undergrad he majored in philosophy, so this will be his first foray into computer programming and statistics. I'm thinking of having him use

Hello R wizards, What is the best way to read a data file containing both fixed-width and tab-delimited files? (More detail follows.) _*Details:*_ The U.S. Bureau of Labor Statistics provides local area unemployment statistics at ftp://ftp.bls.gov/pub/time.series/la/, and the data are documented in the file la.txt <ftp://ftp.bls.gov/pub/time.series/la/la.txt>. Each data file has five

I am a new R user, and am struggling with how to add a comma to the tick mark labels in a bwplot or a boxplot. I think the default values of the labels are fine, I just want them to appear with commas. If I use the function boxplot, I can then use axis(2,labels=format(axTicks(2),big.mark=",")) but that just overlays them on the existing labels which I don't know how to

Hello, Hierarchical factors are a very common data structure. For instance, one might have municipalities within states within countries within continents. Other examples include occupational codes, biological species, software types (R within statistical software within analytical software), etc. Such data structures commonly use hierarchical coding systems. For example, the 2007 North

Hello, I've been very impressed by the reshape package and how easy it makes reorganizing statistical data structures. This makes me wonder if there's another package out there that addresses another set of tasks that one often does when preparing data for analysis. For any particular set of analyses, one typically recodes variables and deletes cases and variables. It would be really

Hi, I have two further comments/questions about large datasets in R. 1. Does R's ability to handle large datasets depend on the operating system's use of virtual memory? In theory, at least, VM should make the difference between installed RAM and virtual memory on a hard drive primarily a determinant of how fast R will calculate rather than whether or not it can do the calculations.

Folks, Haven't been able to find any information on either issue. 1) We have Windows clients (primarily NT4sp6a and WinXP sp1) connecting to Samba servers, and it works fine but the connections are slow. They take 5-10 seconds whereas connections to native Windows servers are nearly instant. 2) The WinXP machines seem to disconnect the SMB session to the Samba servers ASAP rather than

To whom it may concern: I am using R version 1.9.1 beta on a windows machine, and I am trying to use a function called lmer (in packages lme4 and Matrix). I am not sure if this version will support these packages (when I install them from the GUI, the function lmer does not work). I wondered if I need to install a newer version of R, and if so, which version should I install, and how should I

To whom it may concern: I recently used lmer (for non-normally distributed data and mixed effects, using the Laplace method). All 3 of my fixed effects were categorical, including two ordered factors and one unordered factor. In my tables, I currently report the number of observations for the response variable, and both the degrees of freedom and Chi Square values from tests of reduced

Hello, Besides the problem with using "names," one has a similar problem using ".Data" together with "VIRTUAL." Consider the top of p. 295 of the green book. This should work (I had to change "structure" to "junk" because "structure" is a sealed class definition): setClass("junk",
