Vincentizing Reaction Time data in R
I have one more suggestion: Consult a local statistician. Psychology, neuroscience (and a host of other professions that I have encountered) are full of bad statistical practice and reinvention of wheels. "Vincentizing" sounds suspiciously like such an example. A statistician could help you sort it out and either validate the methodology or point you to equivalent more standard versions (and R packages or functions that might implement them) or other better alternatives. Psychology and neuroscience are in particular undergoing public soul searching regarding their research methodology and the irreproducibility of many of their published results. Don't add to the problem: get help from someone local with the necessary statistical expertise. Cheers, Bert Bert Gunter Genentech Nonclinical Biostatistics (650) 467-7374 "Data is not information.

John Kane : I already read the paper and wrote an e-mail to the author, he used matlab and suggested me to ask this same question on this forum. But thank you for your answer. 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.

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. And I failed statistics in school. But a Google search got me to this page, which I hope might be of some help to you. If not, my apologies. https://stat.ethz.ch/pipermail/r-help/2003-May/034272.html [https://stat.ethz.ch/pipermail/r-help/2003-May/034272.html]
I never heard of it either and I passed a couple out of some number > 2 but we always thought the perception and cognition people strange. I think this paper may be a lead. An email to the authors might help http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4017132/ [http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4017132/]
