[R] Difficulty with formatting scatter.smooth output
Hello, I have been using scatter.smooth and been trying to format my plots and been unable to adjust the line type or color of the smooth curve. When I specify col in scatter.smooth, I can adjust the color of the scatter plot points, but the line always stays black and solid. lty has no effect. When I specify par prior to calling scatter.smooth, col will change the color of the points, smoothed line, and bounding box. lty, col.axis, col.lab work as expected. What I would like to be able to do is format each element of the graph specifically - bounding box, points, and smoothed curve. Thank you for any advice. __ [EMAIL PROTECTED] mailing list 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.
Re: [R] Difficulty with formatting scatter.smooth output
From looking at ?scatter.smooth it appears that scatter.smooth uses the function loess.smooth to calculate the smoothed line. So you could create your own scatterplot using the plot function, then call loess.smooth and use the lines function (with whatever parameters you want) to add the line to the scatter plot. This gives you as much control as you want over any of the details. Hope this helps, -- Gregory (Greg) L.

Hi Bing, I had exactly the same requirement, so I modified the original function where you can specify different colours, line widths, etc... (and you can easily add other parameters the same way). I'm attaching my version here, in case it saves you 2 minutes of typing :-) Jose -- Dr. Jose I. de las Heras Email: [EMAIL PROTECTED] The Wellcome Trust Centre for Cell BiologyPhone: +44 (0)131 6513374 Institute for Cell Molecular BiologyFax: +44 (0)131 6507360 Swann Building, Mayfield Road University of Edinburgh Edinburgh EH9 3JR UK __ [EMAIL PROTECTED] mailing list 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.
