[R] Fit elipse to xy scatter

Hi, I know there is a package 'elipse' available but I'm not sure how to use it for my specific implementation. What I would like to do is fit an elipse to two lines of identity (at right angles to each other), as indicated in the following figure: http://imageshack.us/photo/my-images/30/poinca

Re: [R] superscript characters in title with '+'

Hi, Thanks for all of your replies! David, a slightly modified version of what you gave did the trick: hist(X,main = expression("["*Ca**""^paste(2,"+")*"]i"~'onsets')) But I prefer the way '2+' is italicized in the solution Dennis gave: hist(X, main = bquote('[Ca'^'2+'*']i'~'onsets'), xlab

[R] Saving/loading custom R scripts

Hi, How does R automatically load functions so that they are available from the workspace? Is it anything like Matlab - you just specify a directory path and it finds it? The reason I ask is because I found a really nice script that I would like to use on a regular basis, and it would be nice n

[R] Error: could not find function "ad.test"

Hi, I'm trying to run an anderson-darling test for normality on a given variable 'Y': ad.test(Y) I think I need the 'nortest' package, but since it does not appear in any of the Ubuntu repositories for 2.10.1, I am wondering if it goes by the name of something else now? Thanks -- View this me
