Hi, I was playing with Mandelbrot sets and come up with the following code, I thought I would share: library(fields) # for tim.colors library(caTools) # for write.gif m = 400 # grid size C = complex( real=rep(seq(-1.8,0.6, length.out=m), each=m ), imag=rep(seq(-1.2,1.2, length.out=m), m ) ) C = matrix(C,m,m) Z = 0 X = array(0, c(m,m,20)) for (k in 1:20) { Z =

Here's some code to make lissajous dance. I've attached a small sample GIF. Cheers, Rob Steele robsteele at yahoo dot com plot.lissajous = function(omega.x, omega.y, delta = 0, num.thetas = 200) { thetas = seq(0, 2 * pi, length = num.thetas) xs = sin(omega.x * thetas + delta) ys = cos(omega.y * thetas) plot(xs, ys, type = 'l', lwd = 3, ann = FALSE, axes = FALSE) }

Dear R-helpers, Is it possible to create a type of 'movie' in R based on the output of several figures (e.g., jpegs) via the plot() function. I obtained dynamic results with the plotting function and would like to save these as a movie (e.g., avi or other formats)? Regards, Jan _________________________________________________________________ Ir. Jan Verbesselt Research

I was wondering if anyone out there has created a series of images (e.g. jpegs) using R, then animated them on a web page. I have looked around a bit and it seems fairly complicated. One approach that seems sensible is to use a java script that displays the list of images. I have only used html on web pages before so I don't know how to use java... Ideally the final result is easily ported to

hi, is it possible to resize animated gifs with file_column? if i upload an animated gif file with file_column than the animation no longer exists... -- Posted via http://www.ruby-forum.com/.

Hello all I am playing with R for to make a animated GIF. any suggestions, improvements are welcome :-) case somebody could help me, i thanks! Cleber N. Borges ( klebyn ) my objective: (steps TODO) ------------------- 1) to save PNG files; -----> i don't know the best way to make this; 2) transform the PNG files into GIF files (easy! no problem! ... i think ...) 3)

Dear all, I have used RMagic to read and write a image while uploading. An animated gif was read from my local machine and was written in my images folder using RMagick. But the animated gif which i read was witten in my folder without animation. What should i do to write the gif image with animation. Here is my code to read and write image while uploading. image = params[:image][:blob]

I want to get three .gif image files test.1.gif, test.2.gif, & test.3.gif by using a loop. The code I tried is like this: x=c(0, 1, 2, 3, 4) y=c(1, 2, 3, 4) for(i in 1:3) { x11() jpeg("test.i.gif") plot(x, y) dev.off() } but I only could get one image file, test.i.gif. How can I get three image files? Thanks.

I have a data frame with two columns: image pattern 1 http://$IMAGE_ID$ www.url.com/image.jpg 2 $IMAGE_ID$ http://www.blah.com/image.gif ... I want to replace "$IMAGE_ID$" with the corresponding entry in the pattern column such that the result would appear as follows: url http://www.url.com/image.jpg

I'm have a (minor) problem and a question. Problem: The following code creates 5 clusters of dots of different colors. However, I need the second call outside the data.frame call to get the colors to change for some reason. I assume there's an error in the data.frame() call, but I don't know what. Question: Is there is a way to cause the resulting graphic to rotate on it's

Hello, While running the following code I encountered a bit of a funny error. First the code: library(animation) ani.options(convert = shQuote('C:/Program Files/ImageMagick-6.7.0-Q16/convert.exe')) plot.ani<-function() { for (ts in 1:730){ dat<-read.table(paste("c:/temp/ConcProfile_",ts,".txt",sep=""),

I have button that slides down a menu using Effect.BlindDown, but the function that slides it down also makes it so that the opening link now slides the menu back in. If the user double clicks the link (thuse opening & closing immediatley) the slide animation breaks, then will not extend correctly (but no JS errors). How would you go about stopping this happening? Also, is it just me or is

I have an int, ''floorfrozen,'' in my table, ''channels'' that can take a value of 0 or 1. When I render a page, an image in a link_to_remote is called differently depending what the value of channel.floorfrozen is, in a partial, as follows: <% if @channel.floorfrozen %> <%= link_to_remote image_tag("/images/icecube.gif"), {:url =>

Hi all, I'm making an animation of a rotating persp plot of some data. It's easy, really: I just plot the persp in a loop over the theta parameter, saving each plot, and then chain them together with ImageMagick (as suggested on Paul Johnson's R-tips page). But... when you run the animation, because each graph is individually re-scaled, the image is not the same size in each

As a followup to pi-day, I attempted to make a .gif of a simulation based estimation of pi by plotting points inside a single quadrant of a circle (a la?http://www.drewconway.com/zia/?p=2667 ). ?When rendering the individual x,y pairs with points() I intermittently see points crop up around (2,0.5) but the input values for x and y are bounded between 0 and 1. square<-structure(c(0, 0, 1, 1, 0,

Hi, I''d like to call a background image for every item in a list. Something like div#nav li.submenu {background: url(dropmenu.gif) 95% 50% no-repeat;} the image is in public/images/dropmenu.gif Thanks, Peter

I need to make a fairly complex animated graphic and decided to use grid for it. A very simple example of what I need: ##============================================================================== library(grid) grid.newpage() pushViewport(plotViewport()) pushViewport(viewport(xscale = extendrange(c(0, 100)), yscale = extendrange(c(0, 100)))) grid.xaxis() grid.yaxis()

I don't want to get into the debate w.r.t. which IR style is better - ask me over beer if you care about my opinions - but as an FYI, there are serious proposals being worked on to introduce some notion of memory def-use edges to help in analysing memory operations. I don't think we've settled on a concrete proposal yet, but I wouldn't be surprised to see something in the
