The paper said that they had used R ! They must have forgotten to add what may have been a minor bit of use of mintabl I had a look at the equation in the Wiki article and I have long ago forgotten how to read such a thing but I wonder how complicated it is as an algorithm? R is very flexible and it might be fairly easy to just write a function to do it. Actually I just had a very quick look at the Ratcliff paper in Psychological Bulletin 1979, Vol. 86, No. 3, 446-461 (http://star.psy.ohio-state.edu/coglab/People/roger/pdf/Papers/psychbull79.pdf) I am tired and it is not my area of expertise but it does not look too difficult to write a function in R to do this. But I have been wrong before. :) > > John McKown : thanks a lot, this could be a great help to me but I have > to take a closer look. > > Again thank you for your replies. > > Regards, > > -- > Gabriel Weindel > Master student in Neuropsychology - Aix-Marseille University (France) > > > > Le 20/05/2015 18:41, John Kane a écrit : >> John Kane >> Kingston ON Canada >> >>> -----Original Message----- >>> From: john.archie.mck...@gmail.com >>> Sent: Wed, 20 May 2015 09:38:47 -0500 >>> To: gabriel.wein...@gmail.com >>> Subject: Re: [R] Vincentizing Reaction Time data in R >>> >>> On Wed, May 20, 2015 at 5:13 AM, Gabriel WEINDEL >>> <gabriel.wein...@gmail.com> >>> wrote: >>> >>>> Dear all, >>>> >>>> For my master thesis, I'm currently working in cognitive neuroscience >>>> on >>>> executive control through measurement of reaction time and I need to >>>> get >>>> my >>>> data 'vincentized' with an exclusive use of R set by my statistic >>>> teacher >>>> for a test purpose, for this reason I can't use the python code the >>>> lab >>>> team usually uses. >>>> Despite a dozen hours of research I couldn't find any package or >>>> R-code >>>> which would allow the use of vincentization, that's why I'm querying >>>> help >>>> on the R forum. >>>> >>>> So has anyone ever used vincentization in R ? >>>> >>> >>> I haven't.
