Object finalization
...ode the finalizer? R_RegisterCFinalizer accepts a C function, but I can't see how to get it to operate on the pointer, since the pointer is not passed to the function when its called. RegisterFinalizer takes an R closure, but how is it called from R (tried .Internal)? Tim -- Timothy H.

"break" breaks _outer_ loop -- ugh!
It appears that "break" will break from the outermost enclosing loop not the innermost loop. Is it a bug or language feature? Tim -- Timothy H.

name spaces?
...behavior. (An alternate approach would be to use DBI.connect() and add a switch to 'library' or global option that strips off the 'DBI' prefix.) Anyway, it would help in nailing down the DBI interface to know if some name space mechanism is in the works. Cheers, Tim -- Timothy H.

Layout of Fourier frequencies
...but I need to know if I've got this part correct first.) I think in 1D the pattern is: 0 1 2 3 -2 1 (even) 0 1 2 3 -3 2 1 (odd) In 2D is it simply (for a square matrix): 0 1 2 -1 (horizontal) 0 1 2 -1 0 1 2 -1 0 1 2 -1 and the above transposed for the vertical?

Summary of Suggestions for poor man's parallel processing
Thanks to Luke Tierney, Agustin Lobo, Stephen Eglen, A.J. Rossini, Simon Wood and Timothy H. Keitt for responding to my question about poor man's parallel processing. Much of the substantive material was cc'ed to r-help already, but my take is as follows. 1) Currently, there is nothing "simple" for solving my problem. 2) I thought that Timothy Keitt's description of the u...
