...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/poincareplotwip.png/ Conceptually, I'm really struggling to even come up with a way of doing this, let alone an implementation. Would really appreciate some pointers :) -- View this message in context: http://r.789695.n4.nabble.com/Fit-elipse-to-xy-scatter-tp3688117p3688117.html Sent from the R help mail...
