Cognitivemodels

Cognitivemodels is an R packages that provides a number of cognitive models, using a formula interface similar to the aov- or lm-syntax. The models can be fit to data by maximum likelihood, minimum MSE, and more fit measures using optimization routines like rsolnp or Nelder-Mead, and various others. Also, the package provides a model development back end: a class that you can use to develop new cognitive models easily.

    pacman::p_load_gh("janajarecki/cognitivemodels")

You will see a prompt, please type Yes into the console.

    Do you want to install from sources the packages which need compilation? (Yes/no/cancel) 

(Optional) This installs the latest development version of the package:
