In formatR 0.1-5, the dependency on the gWidgets and animation packages are removed. The GUI by gWidgets is optional now. Meanwhile, the function tidy.source() has been moved from the animation package to this package. > library(formatR) > tidy.source(textConnection(' # rotation of the word "Animation" # in a loop; change the angle and color # step by step for (i in

Recently in our R 3.1.0 installation the package formatR was upgraded to version 1.0, doing my usual thing, I got the following error, and the destination html file was not generated. What can I do if I want to stay at the current formatR version? Jun Error: unrecognized fields specified in html_dependency: attachment In addition: Warning messages: 1: 'function (...) {

Good morning folks: Made a second go at installing this and succeeded, but with some strange behaviours along the way. First the system back story. Using up to date edition Ubuntu 8.04 Using up to date edition of R 2.10.1 Using the Toronto, Ontario repository to draw from. After the first attempt ended up with two of the four dependencies installed so only the Rgtk related items would be

Hola: Me suena algo de que el año pasado alguien dijo algo sobre unas sugerencias de reglas de estilo para escribir código en R. No he oído nada más en esta lista (a lo mejor se me ha pasado por alto) Ayer se publicó un mensaje sobre esto precisamente en un blog en inglés: http://pairach.com/2012/06/06/r-style-guide/ (copiado debajo para facilitar la lectura y comentarios en esta lista)

It happens in the token function in gram.c:     c = SkipSpace();     if (c == '#') c = SkipComment(); and then SkipComment goes like that: static int SkipComment(void) {     int c;     while ((c = xxgetc()) != '\n' && c != R_EOF) ;     if (c == R_EOF) EndOfFile = 2;     return c; } which effectively drops comments. Would it be possible to keep the information

Most of my animations that used to work on windows() version 2.11.1 and earlier now flash as if the double buffering is turned off or buffer swapping is triggered by other events than in the past. The simplified example below using symbols should illustrate the problem in a windows environment. windows() radius <- 8 n <- 6 ang <- seq(0,2*pi,length=n+1)[-(n+1)] ca <- cos(ang) sa

I needed to clean someone else code and run it through tidy.source. It encountered a number of hangups which after some experimentation lead me to suspect that the culprit is # symbol when it is a part of literal string. For example if i copy the following to the clipboard confuse.tidy <-    function() {   txt <- 'abra # cadabra' } and run with default arguments >tidy.source()

Hi list, Could anyone recommend some good website for formatting R code? For example, when you copy paste R code to gmail and back to R, it loses its format, the dash symbol causes errors. I've had someone used it to format my code here on the list, but can't find it anymore. Mike [[alternative HTML version deleted]]

Hi I'm seeing some "odd" behaviour with cbind(). My code is: > cat <- read.table("cogs_category.txt", sep="\t", header=TRUE, quote=NULL, colClasses="character") > colnames(cat) [1] "Code" "Description" > is.factor(cat$Code) [1] FALSE > is.factor(cat$Description) [1] FALSE > is.factor(rainbow(nrow(cat))) [1]

Does: rainbow(3)[1] rainbow(3)[2] rainbow(3)[3] ... solve your issue?

Hi, I am using a old code (probably written for R 2.5) and it stops when calling rainbow() with gamma argument. I saw that gamma argument is not present in newer version of R rainbow function. How can I translate this line of code: rainbow(100, s = 1.0, v = 0.75, start = 0.0, end = 0.75, gamma = 1.5) ? It fails with: Error in rainbow(100, s = 1, v = 0.75, start = 0, end = 0.75, gamma = 1.5) :

Hi R folk I have a distance time graph for a locomotive and at various times different events occur on board the loco. I want to put a vertical line on the speed time graph for each event, but I want to colour each different kind of event differently to see visually whether there's any pattern to these events happening. I could just create a vector of colours and use abline which is easy

I have 11 vectors representing insect survival probabilities in response to different levels of toxins at 10 concentrations lx100=c(1,1,1,.8,.5,.4,.2,0) day100=c(0,1,2,3,4,5,6,7,8) lx90=c(1,1,1,1,.9,.8,.6,.4,.2,.1,0) day90=c(0,1,2,3,4,5,6,7,8,9,10) #...and so on10% and a zero (control) series lx0=c(1,1,1,1,1,1,.9,.9,.8,.8,.6,.5,.4,.3,.2,.1,.1,0)

I've tried looking at ?colors and ?palette and if I'm understanding it correctly, I'm supposed to type in (for example) palette(rainbow(13)) before I type in my plot (of 13 lines) if I want 13 different colors. But this does not work. Other things that i have tried besides rainbow give me errors. Am I just doing something completely wrong? Anna

Dear r-helpers, Can one save a dynamic graphic produced by rgl, e.g.: open3d(); x <- sort(rnorm(1000)); y <- rnorm(1000); z <- rnorm(1000) + atan2(x,y); plot3d(x, y, z, col=rainbow(1000), size=2) as a dynamic figure that can be embedded in a pdf? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400

Hi I use pixmapIndexed tmp.vimp <- array(0,c(x.dim,y.dim)) tmp.vimp <- pixmapIndexed(tmp.vimp, col=rainbow) to plot values of a 2D matrix. I 'fill' the pixmapIndexed like: for (x in 1:x.dim) { for (y in 1:y.dim) { tmp.vimp at index[x,y] <- my.matrix[x,y] }} how can I define, that the colors are painted e.g. according the rainbow

Hi, how can I create a rainbow gradient in R? For example, let's say I have a plot of y = x...and I want the plot to go from red -> orange -> yellow -> green -> blue -> etc. Right now, I know how to do something like go from red to blue, using the plotrix library: library(plotrix) redToBlue <-
