Journal of Open Source Software

A week ago, I received a request for refereeing a paper for the Journal of Open Source Software, which I have never seen (or heard of) before. The concept is quite interesting with a scope much broader than statistical computing (as I do not know anyone in the board and no-one there seems affiliated with a Statistics department). Papers are very terse, describing the associated code in one page or two, and the purpose of refereeing is to check the code. (I was asked to evaluate an MCMC R package but declined for lack of time.) Which is a pretty light task if the code is friendly enough to operate right away and provide demos. Best of luck to this endeavour!

Of hunter-gatherers and R packagers

After an exhausting day spent in the train to escort my daughter back from Petite Bretagne, I came home to read about the on-going action of the North Sea fishermen, who blockaded the North Sea ports protesting against the EU fishing quotas.

I usually find the train a great environment to work and this was true on the morning trip where I spent three hours building the R package for our new MCMC book with George Casella. [But on the way back, there were noisy people all over the place and concentrating was a problem…] It took me two days to understand the structure of writing R packages, first by mimicking the LearnBayes package of Jim Albert, then by reading the on-line available documentation. Once I got over the error messages than seemed to imply I did not have the right version of R and once installed the additional codetools package, due to Luke Tierney, I managed to run

R CMD check mcsm

R CMD build mcsm

R CMD INSTALL mcsm

satisfactorily, including the documentation (the worst part!)… I have done the first four chapters so far and the remaining chapters should follow rather quickly. This is quite comforting because this is the very last step of writing the draft of Enter Monte Carlo Statistical Methods (this is the current title, by the way).

PS-Getting back to those fishermen, I quite understand their plight, i.e. that the current quotas are pushing them out of business, but the answer from the French government, namely to sponsor them for not fishing rather than for changing jobs, is absurd. There is enough evidence to support the thesis of a depletion of the fish population in the North Sea and the Atlantic to understand that the culture of hunting-gathering that still underlies commercial fishing is not sustainable. Some species like the tunas are already close to extinction if nothing short of a ban is enforced. This is obviously tough on tuna hunter-gatherers, but they must be stopped…
