2 # Mini tools for Galaxy scripting
3 # Coded by: M.Petera,
4 # - -
5 # R functions to use in R scripts and wrappers
6 # to make things easier (lightening code, reducing verbose...)
7 # - -
8 # V0: script structure + first functions
9 # V1: addition of functions to handle special characters in identifiers
