Final question: in your code you have mean(M[t-1L,]): what is the 'L'
for? I removed it at apparently the code produces the same output...
<SNIP>
The constant "1L" is stored as an integer; the constant "1" is stored as
double precision. This sometimes makes no difference and sometimes
makes a huge difference (especially in the context of numerical
comparisons). If something is supposed to be an integer it is safer to
use the "L" form.
See ?NumericConstants.
