Re: [R] filling the area

Ok. I´ve tried before and all I got was a polygon indeed with the extremes points connected. Please where is the error ? polygon(x,y,col=gray, border = red) Benilton Carvalho escreveu: take a look at: ?polygon b On Jan 25, 2007, at 8:18 AM, Mauricio Cardeal wrote: Please, how to fill

Re: [R] filling the area

Thank you all. One more question about the syntax below: min(y) twice, is it? polygon(c(min(x), x, max(x)), c(min(y), y, min(y)), col = blue) polygon( c(min(x), x, max(x)), c( min(y), y, min(y)), density=100 ) Best whises, Mauricio Marc Schwartz escreveu: On Thu, 2007-01-25 at 10:18 -0300,

Re: [R] filling the area

Yep. Keep in mind that you need to define the complete boundaries of the region to be colored. So you need to add the coordinates of the lower left and lower right hand points, which are [min(x), min(y)] and [max(x), min(y)]. HTH, Marc On Thu, 2007-01-25 at 11:14 -0300, Mauricio Cardeal wrote:

[R] filling the area between two curves in a plot

Hi, does anybody know how I can color the area enclosed between two curves on a plot? Thanks, --- Rajarshi Guha [EMAIL PROTECTED] http://jijo.cjb.net GPG Fingerprint: 0CCA 8EE2 2EEB 25E2 AB04 06F7 1BB9 E634 9B87 56EE

RE: [R] filling the area between two curves in a plot

Assuming the coordinates for the two curves are x1, y1, x2 and y2, and that the pairs are sorted by x1 and x2, respectively. Then just do something like: polygon(c(x1, rev(x2)), c(y1, rev(y2), ...) HTH, Andy From: Rajarshi Guha Hi, does anybody know how I can color the area enclosed
