Partools 1.1.4. August 21, 2015. Partools 1.1.4 is now on GitHub. The main change this time is enhancement of the debugging facilities (which work not only for partools. But also the cluster-based portion of R’s parallel. Package in general). As some of you know, I place huge importance on debugging, so much so that I wrote a book on it (. The Art of Debugging with GDB, DDD, and Eclipse. N Matloff and P. Salzman, NSP, 2008). But debugging parallel code is hard, especially in the parallel. Package with Yi...

June 4, 2015. In programming, sometimes it’s useful to write a. Rather than a function. (Don’t worry if you’ve never heard the term before.) In this post, I’ll give an example of use of macros in R. using the gtools. I wanted to write some utility code to help me reuse my earlier R commands during an interactive R session. Most (though not all) of what I wanted is already provided in the excellent R user interface systems such as ESS. Choose one of the recent commands for re-execution. In which to goal i...
