Hi, Is there a way in R to plot an envelope line from a cloud of points (x, y data) ? That is, a smooth line that include all points, where the points do not follow a strait linear pattern. Could somebody redirect me to some package or function for this? Thanks in advance. Juli -- http://www.ceam.es/pausas
smooth is in the eye of the beholder, but you could look at the function convex.hull in the package tripack. url: www.econ.uiuc.edu/~roger Roger Koenker email rkoenker at uiuc.edu Department of Economics vox: 217-333-4558 University of Illinois fax: 217-244-6678 Champaign, IL 61820 On May 5, 2008, at 7:56 AM, juli pausas wrote:> Hi, > Is there a way in R to plot an envelope line from a cloud of points > (x, y data) ?
