Hi, I have a couple of questions: * would it be possible to add more information on the history, for example the number of the command and a timestamp. With the number of command, one could do some stuff like in a terminal to recall a specific command : $ !45 and with the timestamp, one could imagine to ask for commands that were typed in a given interval of time. For example : R>

Hi, Consider the code : g <- function(){ print(.x) .x <- 3 } f <- function(){ environment(g) <- environment() .x <- 2 g() .x } > f() [1] 2 [1] 2 I would like f() to return 3. How can I do that ? Am I completely out of place ? Doing that, I want to avoid to pass .x as a parameter in f, because in real life .x is pretty big and g() is called over and over in a

Hi, I'm trying to build a simple R package 'helloWorld' with just one function that prints 'hello World' on the C side. I agree that it is completely useless, but I just start mixing R and C. My C file is as follows : #include <stdio.h> void helloWorld() { printf("hello world !\n") ; } When I call it from R, here is what happens : R>

Hi, Sometimes I need to consult the history of commands that are matching a regex, so I modified the utils::history function for that purpose. I found it useful. I append the code ( I only added the two lines with #**) Romain. history2 <- function (pattern="", max.show = 25, reverse = FALSE, unique = pattern!="", ...) { file1 <- tempfile("Rrawhist")

Dear R users and developpers, My question is adressed to both of you, so I choose R-help to post it. Are there any plans to jazz up the main R website : http://www.r-project.org The look it have now is the same for a long time and kind of sad compared to other statistical package's website. Of course, the comparison is not fair, since companies are paying web designers to draw lollipop

I''ve recently made a first release of what I''m calling "bundled_resource" which is a plugin that makes our lives *much* easier when we need to use javascripts, stylesheets and images in conjunction with one another to deliver a special effect or tool on the client (browser) side. If you missed the release, read about it on my blog at

Hi all, I'm trying to superimpose a rchisq density line over a histogram with something like: hist(alnlength) lines(density(rchisq(length(alnlength), 4)),col="red") But the rchisq line won't appear anywhere, Anyone knows what I am missing here? Thanks in advance, Albert.

I agree with Martin "R Graph Gallery" has a lot of neat stuff. I also think there should be a on CRAN website a list of "R websites". And in a perfect world one of the search engines scope would get extended to search them all.

I'm sure I'm being stupid so flame away... R2.2.1 on Windoze (boohoo) latest updates of packages. I'm exploring a dataset (land) with three variables looking at an narrowly unbalanced two group (GROUP) ANCOVA of a randomised controlled trial analysing endpoint score (SFQ.LOCF.ENDPOINT) entering the baseline score (SFQ.BASELINE) as covariate and the following work fine: > res.same

I seem to remember reading somewhere about some style guide regarding R the number of comment characters (#) prior to the comment meaning something. Anyone know to what I'm referring? Where? ---------------------------------------------------------- SIGSIG -- signature too long (core dumped)

Hi R users This looks a simple question Is there any difference between between rnorm(1000,0,1) and running rnorm(500,0,1) twice in terms of outcome ? TM

Dear r-list, I am trying to visually seperate the two main clusters of a dendrogram. The idea is to use: 'edgePar=list(lty=3)' for 'dend1[[1]]' and 'edgePar=list(lty=1)' for 'dend1[[2]]' I have not found a way to solve this. Any suggestions? Patrick hc <- hclust(dist(USArrests), "ave") (dend1 <- as.dendrogram(hc)) par(mfrow=c(2,2)) plot(dend1)

Dear R-help, This is my first R day. I want to ask some more beginner's questions. Q1. How can I obtain the covariance matrix for parameter estimates of a multiple regression? I checked ?lm but didn't get the information. Q2. How can I see the old graphs in the graph window? Q3. Can R plot animated graph? For example, I want to see the dynamic change of a 2D graph during a time

When using drag and drop, the browser window will not scroll if you move the mouse off the page. This makes it very difficult, if not impossible to create certain types of web applications. I know this has been mentioned before and is on the Wish List, but it''s very frustrating. If you look at this other Javascript library called "Drag''nDrop & DHTML Library"

Does anyone have an idea of how to make a chart in R like the ones here that use a graphic: http://bigpicture.typepad.com/comments/images/slide1.gif

Folks, I was drawn to R, like many others, partly for the opportunity to draw nice, colorful graphs (occasionally ones with meaning, too :-) ). I am still quite a newbie to R. As such, I have been trying to understand the code for the graphics on the home page (the ones from the 2004 contest -- the dendrogram, the cluster plot with different coloured circles, etc.) I was wondering whether anyone

Dear All, I have a question on overlaying a filled.contour (e.g. on soil properties data) and contour (by elevation) in one graph. Both have the same z matrix dimension. I'm able to overlay both graph, but the plots dimension did not overlap well on the same plots. How can I have both filled.contour and contour on the same graph? The commands that I have written are as follows:
