The erpR package includes a series of functions for importing Event-related potential (ERP) data, carrying out exploratory analyses, computing traditional ERP measures and ERP plotting.
erpR package is dedicated to the analysis of event-related potentials (ERPs). Event-related potentials are the measured brain responses associated with a specific sensory, cognitive, or motor event and are obtained from electroencephalographic (EEG) signal. The
erpR package contains a series of functions for importing Event-related potentials (ERP) data, carrying out exploratory analyses, computing traditional ERP measures and ERP plotting. Many
erpR functions require to specify two arguments:
numbers. The names of the objects for the
erpR functions are obtained from the combination of
numbers. The argument
base typically indicates the name of the experimental condition (or group, or both), while
numbers indicate the numbers of the subjects on which function is applied. This system is crucial to keep order in objects and files names and to tell
erpR the correspondence between the objects. In particular a given
base will always refer to the same condition, and a given
number will always refer to the same subject. The data frames containing ERP data (named by the combination of
number) are stored in lists called erplists.
