image(x,y,z, col=gray(0:19/19),xlab="x", ylab="y") contour(x,y,z,xlab="x", ylab="y") persp(x,y,z, col="gray")
Thanks, I've had a play with some of these and they look good. A very minor bug report is that the help for contour says that the source is in `$RHOME/src/main/plot.c' but it is actually in `$RHOME/src/main/plot3d.c' (might as well be fixed until someone makes real documentation). One other thing is that the contour() command will only draw contours where the x and y dimensions match. I went through the code and found the check that generates the error but there is no comment to explain why the check was put in there but it could be a simple thing to extend it to rectangular grids. - Tel -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
