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>

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

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")

Hi, Has anyone started a javascript device for R. I don't see something like that googling or at on http://www.stat.auckland.ac.nz/~paul/R/devices.html For example, using that graphics library : http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm (I cc that message to the author.) ps : this is not a feature request, i will do it. But if someone has started that, let me know. Romain --

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 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'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

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 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:

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

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-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

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

Bonjour, je travaille actuellement sur le logiciel R et mets en place des procédures d'analyse de données : sur des procédures de classification employant la commande dist(), je rencontre des problèmes de memoire : avec des data.frame d'environ 100 000 lignes j'obtiens le message d'erreur suivant : Error : cannot allocate vector of size 668 481 330 Ou une autre erreur souvent

Hello, Suppose I simulate 20 observations from the Poisson distribution with lambda = 4. I can summarize these values using table() and then feed that to barplot() for a graph. Problem: if there are empty categories (e.g. 0) or empty categories within the range of the data (e.g. observations for 6, 7, 9), barplot() does not include the empty cells in the x-axis of the plot. Is there any way to

hello, I have just started using R for doing a project in time series... unfortunately, I am having trouble using the read.table function for use in reading my data set. This is what I'm getting: I inputted: data <- read.table("D:/Oliver/Professional/Studies/Time Series Analysis/spdc2693.data", header = TRUE) I got: Error in file(file, "r") : unable to open connection

Hi, I'm trying to draw a 2D plot using multiple tints of red. The (simplified) setup is the following: || year | x | y || My idea is that each year is plotted with a different tint of red. Older year (lightest) -> Later year (darkest). I've managed to plot this with different scales of grays simply by doing: palette(gray(length(years):0/length(years))) before the plot and for each

I came across this one: http://www.nysun.com/article/32787 which says that the violent death rate in Iraq (which presumably includes violent deaths from the war) is lower than the violent death rate in major American cities. Does anyone have any insights from statistics on how to interpret this?
