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.
