Hello all!
I would like to create a 3d plot, with the option price explained
by the underlying price and time. Unfortunately, I can't quite
get it to work. I would very much appreciate your help!
The usual problem with lattice calls that you "can't quite get ...
to work" is failure to read the R-FAQ ( or the help(lattice) page)
where it is explained that you need to print() the function result.
At the moment my R-machine is tied up with a long process but try
wrapping print() around that wireframe call.
There is an error message in the actual plot.
Error using packet 1.
NAs not allowed in subscripted assignments.
When I got around to running it I was hampered by a lack of knowledge
about what sort of data-object "price" might have been. I tried
putting in a single number on hte theory that it would saitisfy the
seq() call, and also got the error you report. More input is needed
from the OP about the problem specification, and hopefully she will
provide a test dataset.
