Dear Jeff,
There was a problem in LYGH and lapply threw an error, but
mclapply got stuck in an infinite loop. The doc for mclapply says that mclapply
runs under try() with silent = TRUE. So that means mclapply should run
properly, i.e output a try class object and exit. But it didn't. Can you shed
some light on why this happened?
THanking you,
Yours sincerely,
AKSHAY M KULKARNI

It does not look to me like you are providing the necessary arguments to arfima.
Try making this work with lapply first... then try mclapply.
