Thanks for this,

With the data i have what is the best method to convert it into the required matrix, as i am a little unsure how it would be done - i imagine this must be a common task?

Those points don't form a surface that wireframe could draw. cloud() would work, but if you want a wireframe surface, then the FD values need to be something like what persp() needs: a matrix of values, with rows and columns being combined values from Elevation and Temperature. wireframe() is different in that the matrix is presented as a column in the data, with the rows and columns repeated correspondingly.

See the g dataframe produced in example(wireframe) for an example of the right sort of structure.
