run1 <- list(Dom = (my_vector), mean = (my_single_number))
I can do that in a for loop for 40 runs, ending up with 40 lists: run1,
run2, ..., run40.

segfault while running an R script
> MS <- floor (log2 (MinFileLen)) #NUMBER OF DECOMPOSITION LEVELS
*** caught segfault ***
address 0x31343142, cause 'memory not mapped'
Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Any idea ? Thank you in advance.
