Dear Samuel, Many may object (for good reasons) that adding options would clash with functional paradigm, but it is possible. I don't know about the least worse practice but as far as I would do it, you could:
1. directly write and then read elements in the (hidden) list .Options that is present in the global environment: options(test = "blabla") ## add element in .Options .Options$test ## read element (for use in your own function) 2. you could also create your own alternative to options(), as ex: https://github.com/courtiol/IsoriX/blob/master/IsoriX/R/options.R Option 2 has the benefits of not risking conflict with existing names in .Options and it would thus also not mess up the way other packages may work. Option 1 uses what is already in place. I hope this help, Best Alex On Thu, 6 Sep 2018 at 17:18, Samuel <samuel.granje...@inserm.fr> wrote: > Hi, > > I would like to change the default value of some arguments of some > functions in a package of mine.
