...he flexibility of the R environment. The eaze with wich I was able to generate simple plots of my EEG data made me wonder if someone tried to implement an ERP package. For the non-cognitive scientists ou there: EEG is electrical activity measured from the scalp (usually multi-lead) that is used in psychophysiological experiments to infer cortical activation. In a typical experiment this data can be linked to events: usually stimulus presentations, to calculate 'trial means' in distict trial subcategories. Did someone out there made an effort to put together some sort of package for the analysis of...
