similar to: x labels out of Quartz canvas

Hi, I finally came up with a nice colored matrixplot, using the color2D.matplot function of the plotrix package. But I can't assign xtics and ytics to this plot. I made sure that the matrix has correct colnames() and rownames(). Here's what I do: a=matrix(1:16, 4, 4) colnames(a) <- c("X1", "X2", "X3", X4) rownames(a) <- c("Y1",

Hi I am relatively new to R and am trying to figure out to plot 3d scatter plot using defined colors based on x-axis and y-axis values. Right now in the code below, I assign colors based on certain values in the names of the x-axis. Now if I want to extend the condition to assign a color based on the names of both x-axis and y-axis values, what should I be doing? Any help or ideas would be

Dear R devel I've been wondering about this for a while. I am sorry to ask for your time, but can one of you help me understand this? This concerns duplicated labels, not levels, in the factor function. I think it is hard to understand that factor() fails, but levels() after does not > x <- 1:6 > xlevels <- 1:6 > xlabels <- c(1, NA, NA, 4, 4, 4) > y <- factor(x,

Hello :-) I am trying to run the next script, it generates "random areas" inside a map of the american continent, and then plot it, it?s suppose that every frame gives you the evolution of the program but at some point it stops with the weirdest of the errors I?ve ever seen in R, I don?t even have a line like that :-| Error in if (random_matrix[x_list[random_sq] - 1,

Hi! I want to display 2 graphs with different number of data points on the x-axis. The code below scales them so it seems that testtwo has the same number of data points as testone. How can I fix that? thanks. z<-1:50; x<-1:100; plot(x,testone,type="l",xlab="",ylab="",main="",lty=4,axes=FALSE,ylim=c(-1.0,1.0),cex=1); par(new=TRUE);

I noticed something strange in my app today. It appears that the extra canvas path appended in url_for is back but only for controllers that are not resources. Here is an example I have in my site: campaigns is a resource checkout is not # With the canvas false flag (rdb:1) @controller.url_for(:controller => ''campaigns'', :action => ''show'', :id

How can I use the drawing canvas and its off-screen image buffer, say FXImage, to dynamically resize or have its width and height attributes changed in reply to user interaction with the main window (FXMainWindow)? It seems that whem I put initial values to W and H of the canvas or FXImage, they remain with its initial values no matter what I do whem resizing the main window. -- Ranieri Barros

Hi all, Just looking for a quick sanity check. I was thinking of writing a plugin for rails to give rails developers a good way of using the new firefox 1.5/safari canvas tags. I was thinking of grabbing an existing ruby graphics library and modifying it so that it renders via the canvas tag.. So you could have link_to_remote pointing to controller actions that instead of returning

Hi, canvas is a new R package implementing a graphics device that emits javascript code conforming to the HTML 5 CanvasRenderingContext2D interface. Available on CRAN soon, but you can get it here immediately: http://www.rforge.net/canvas If you have access to a beta web browser like Firefox 3.1 or later, you can see example plots here: http://www.rforge.net/canvas/plots/index.html

Hello, I want to save a pdf plot using Cairo, but the canvas of the saved file seems too large when compared to the actual plotted area. Is there a way to control the relation between the canvas size and the size of actual plotting area? Thanks in advance, and best regards, Eduardo Horta [[alternative HTML version deleted]]

I just encountered a bug that caused the links in my partials to be generated as non-canvas routes when the partial was loaded via ajax. This bug is due to facebooker url rewriting checking for fb_sig_in_canvas to determine if the application is running in or outside a canvas, and fb_sig_in_canvas is not sent for ajax requests. My hacked together patch diff is below, sorry I didn''t have

I have been checking the params for params[:fb_sig] to detect if the client is in the Facebook canvas, but those don''t work at the beginning of a controller when you''re calling before_filters. I have a require_login in the before_filter, but I want to skip it if the user is from Facebook. So are there any other ways to check that the client is coming from the canvas?

In Splus, I often use graphics windows with a black background and white foreground. The S print.graph() function sends the current plot to my printer but with a white background and black foreground. I'd like to be able to do something similar in R, but can't figure out how. I've tried various permutations of dev.copy() and dev.print(), but it seems that the foreground color is

Hi, I think that R-tcltk doesn't have the capacity to display an image stored in memory on a tkcanvas object, am I right? I have digged around everything I can find from Peter Dalgaard and tcltk references and drew my conclusion. Can you, Peter, or some other gurus on the list, give us a pointer or two on how to proceed to solve this problem? I am afraid that it may involve writing C

Muchísimas gracias Carlos, de verdad que te agradezco la ayuda, pero no es lo que voy buscando. Quiero colocar en el eje de abscisas la secuencia temporal de los meses, es decir, agosto septiembre, octubre, etc? pero no las fechas de las toma de datos, sino que aparezca la marca de un mes, y la siguiente marca sea la del siguiente mes, etc?, y además que las muestras estén separadas de acuerdo con

Background: I'm trying to make sure my Unix and NT users are being assigned the correct UID from both platforms so they own files correctly from both sides. I was hoping to avoid username maps since our users with cross platform access already have matching usernames on both sides (or will when we reconfigure). I've been playing with several parameters, and fixed some things, but I did
