Hi Simon, Thanks very much for this. Very much appreciated. I will communicate with the package authors but they only support windows and linux at the moment. I was hoping it would be straightforward to get it to work for Mac OS and then send them a patch. From what you say, it shouldn’t be too difficult. I will try next week but I may need a bit more help.
BTW the package is really cool. It allows you to call R from Haskell in an integrated way. I need to be able to perform non linear least squares and there is no existing library in Haskell to do this; enter R :-) Thanks once again, Dominic Steinitz [email protected] http://idontgetoutmuch.wordpress.com On 30 May 2014, at 15:36, Simon Urbanek <[email protected]> wrote: > > On May 30, 2014, at 6:07 AM, Dominic Steinitz <[email protected]> wrote: > >> My googling skills are failing.
