MEA class constructorThe preferred way to create an object of class MEA is through the function readMEA.
MEA(
dataframe,
sampRate,
filter = "raw",
id,
session,
group,
s1Name,
s2Name,
uid = paste(group, id, session, sep = "_")
)is.MEA(x)
a data frame with 2 columns containing MEA data respectively for subject 1 (s1) and subject 2 (s2).
integer. The sampling rate of the MEA data. Normally derived from the framerate of the analyzed video sequence (frames per second; fps).
a string describing the pre-processing that has been applied on the raw data.
a string representing a unique identifier of the dyad that the MEA data belong to.
an integer representing the session (or experiment, interaction, etc); if each dyad is measured only once, the default value is 1.
a string naming the group the dyad belongs to, such as diagnostic group, clinic, etc.
a string naming subject 1.
a string naming subject 2.
a string providing a unique identifier of the file. By default 'group_id_session'.
object to be tested.
A list containing three objects:
MEA: the dataframe containing the motion energy data
ccf: the matrix of lagged cross-correlations between s1 and s2 (if MEAccf was run)
ccfRes: some useful row marginals
is.MEA returns TRUE if and only if its argument is of class MEA
It is advised to not create the MEA object manually but to always use the function readMEA instead.
