Hi Carlos, Thanks for the response. The plot you suggested was not in line with what I'm trying to produce in R. The last plot found at:
http://www.advsofteng.com/gallery_contour.html is more along the lines of what I'm looking for. Notice the scatter points (shown by "x") are not laid out in a regular/gridded fashion, yet the plotting software was still able to use some kind of interpolation and plot contours. All the contouring options I'm finding in R require the spatial locations of data points to be in a 'regular' grid. That is, data in each row must have the same y coordinate and data in each column must have the same x coordinate. I'm seeking flexibility in the location of the points on which the contours are based. -- View this message in context: http://r.789695.n4.nabble.com/contouring-x-y-scatter-data-tp3912828p3913544.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org 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.
