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) }

These are the ways that occur to me. ## This produces a logical vector, which will get converted to a numeric ## vector the first time a number is assigned to it. That seems ## wasteful. x <- rep(NA, n) ## This does the conversion ahead of time but it's still creating a ## logical vector first, which seems wasteful. x <- as.numeric(rep(NA, n)) ## This avoids type conversion but still

I'm finding that readLines() and read.fwf() take nearly two hours to work through a 3.5 GB file, even when reading in large (100 MB) chunks. The unix command wc by contrast processes the same file in three minutes. Is there a faster way to read files in R? Thanks!

Hi! Coral isn''t working from Xen. If you can please try it, maybe i''m just doing something wrong. However it works from outside Xen with the same setup. Can Xen cause this kind of DNS errors? Try something like: http://www.scs.cs.nyu.edu.nyud.net:8090/coral/ or http://www.google.com.nyud.net:8090/ -- /Varga Péter/ ------------------------------------------------------- The

Folks, I am terribly puzzled by an issue reported as bug 2381 [http://bugs.centos.org/view.php?id=2381] ? definitely an upstream bug, as it does the same under X/OS 5 and StartCom 5. Simply put: Hibernation fails with horrendous I/O errors after swsusp starts dumping to swap. What bugs me is that hibernating from the CentOS 5 LiveCD *works*!!! (on the same hardware) How could I investigate to

Hello List, A special thanks to Mr John Terpstra for helping me get back on the straight and narrow with an install of Samba 2.2.5 on RH8 . 1)I needed to remember the installation is linux centric, do the permission's based on linux ........ 2)I needed authorization to access the files, if you set " permission's to ''share", make "share" the viable
