hi, 1. How to find the best fit of inner cut ellipse to points in polar plot?
2. How can we find the ellipse passing through most of the points in polar plot? And can we get the center x, center y, major radius, minor radius, and rotation angle of the ellipse? The csv data is attached. Thanks. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
