All,
I've read several tutorials re: generating wireframes, but am clearly
missing something. I have data along the lines of:
tbl [1:10,]
Visits Activity Course.Grade
1 17 2 18.31
2 7 11 20.67
3 9 17 24.69
4 28 71 38.72
5 43 107 45.46
6 14 5 47.77
7 25 51 57.81
8 32 27 59.46
9 60 43 64.39
10 31 46 66.26
Looks like you are after a 3D scatterplot rather than a wireframe - the
latter only works on a regular grid of Vistits and Activity.

When I run the command:
wireframe(Course.Grade ~ Visits * Activity, data = tbl)
I get an appropriately labeled, but empty, cube. Can anyone tell me
why there's no data in my cube?
Thanks in advance,
David
