Dear all, I would like to plot under the same plot many curves like mycdf<-ecdf(runif(100)) plot(mycdf) curve(mycdf,from=-1,to=1) mycdf<-ecdf(runif(200)+3) plot(mycdf) curve(mycdf,from=-1,to=1) as you can see each new call to curve redraws (erases) the window. How I can have an effect like plot(mycdf) lines(mycdf2) lines(mycdf3) I would like to thank you in advance for your help

Hello everybody I'm trying to write a simple version of matlab's "quiver". The idea is that I have fluid with velocity defined on a grid. I have a matrix of x-components of velocity and a matrix of y-components and I want to see the overall flow pattern. (I work with 2D fluid mechanics problems). My first-stab function is below: quiver <- function(u,v,scale=1) # first

I am trying to figure out how to use rgl package for animation. It appears that this is done using the play3d() function. Below I have some sample code that plots a 3D path and puts a sphere at the point farthest from the origin (which in this case also appears to be at the end of the path). What I would like to do is animate the movement of another sphere along the length of the path

Hello, I'd like to be able to set options for grid and lattice globally, once for all subsequent plots, just like what ps.options() does. I walked through the functions of Grid and didn't find it. The following are related things that are available: get.gpar() trellis.par.set() any ideas? thanks.

Hello all, I set 'UDUNITS_PATH' and 'NETCDF_PATH' successfully to my custom places and then % R CMD INSTALL RNetCDF_1.1-3.tar.gz and got this: ... checking for executable suffix... checking for object suffix... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for main in -lnetcdf... yes checking for main in -ludunits...

Is there a command that marks the screen as "dirty" and hopefully redraws it? If I do a control ALT F1 and the F7 this in effect redraws the screen. I am getting video artifacts that I think is in the nvidia driver. the switching console works - I was just hoping there is a more convenient way. some command or something. Thanks, Jerry

Hello, Does anyone know how to make "movies" in R by making a sequence of plots? I'd like to animate a long trajectory for exploratory purposes only, without creating a bunch of image files and then using another program to string them together. In Splus I would do this using double.buffer() to eliminate the flickering caused by replotting. For instance, with a 2-D trajectory

Dear list, I would like to plot arrows with different colors according to arrow length, and also (if possible) with head size proportional to arrow length. The idea is to make a quiver-like plot of matlab with wind speed data. So far, I´ve been able to use different colors, but I need to find a more efficient way to recode arrow length intervals into colors. On the contrary, I can't define

Hi All, Over the years, I have written a number of custom time series graphing modules (in ANSI C). I want to make these graphs available in R. After considerable thought (as well as feedback fom this NG - thanks go to Don MacQueen and Paul Murrell), I have decided to re-write (atleast some of the routines in R). Basically, this is what my R function needs to do: 1. create a parent

Hi All, I'd like to plot something like http://www.nawcwpns.navy.mil/~weather/mugu/mesodata/analysis.html Looking through the galleries at http://addictedtor.free.fr/graphiques/allgraph.php http://r-spatial.sourceforge.net/gallery/ http://fawn.unibw-hamburg.de/cgi-bin/Rwiki.pl?GraphGallery demo(graphics) I did not find a function to plot a 2d field on a matrix. I did find mention of a

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 have finally received and am configuring my new workstations eith the NVS510 graphics cards, and have run into rather a problem. The X server seems to be loading the NOUVEAU driver properly (based on the contents of Xorg.0.log), but I have one X11 application that doesn't work correctly; it runs as though XSynchronized is always True, even though it's explicitly set to False in the

Hi, The minimize plugin conflicts with Animation. For example, it doesn't let Animation draw shade animations, and interferes with other window event animations. The animation plugin now minimizes the relevant effects to taskbar, so using the two plugins together doesn't make sense anymore. Moreover, by default Animation is off, Minimize is on, and when users enable Animation, naturally

Hi The current status is that I am keen for people to contribute some testing code (see https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951) There were also some getGraphicsEvent() changes/fixes suggested by Richard Bodewits (cc'ed), for which I am also seeking test code.

Hi, Having the minimize_open_close option in Fade wasn't enough for conflict resolution with Animation, since it was on by default. This makes sense since the Minimize plugin is used by default, which is a lightweight animation provider that some people/distributions might prefer over Animation. And nobody really needs to know that this option resolves the conflict. So here is a better method

Hi, I just installed R and am comparing it to other packages (such as Igor). So, you'll have to excuse me if this is a stupid question. I run the simple command: plot(1:1000000) And it seems SO slow! Igor blasts through this. My theory is that R is redrawing the screen for every point that's being graphed. Is it possible to control how often R redraws a plot as its building it -

This is an announcement of the release of an R package 'formatR', which can help us format our R code to make it more human-readable. If you have ugly (I mean unformatted) R code like this: ?# rotation of the word "Animation" # in a loop; change the angle and color # step by step for (i in 1:360) { ? # redraw the plot again and again

Anybody else notice how poorly Firefox 3 update on CentOS-5 works via NX connection? Any suggestions on fixing the visual artifacts/bad redraws? Craig

Hi Taking a look at those patches is now on my todo list, so I may be in touch with both of you at some point to request some testing.
