later
(Package: Laterality) :
later: this function calculates handedness index (HI) and z-score.
Returns an array with x dimensions corresponding to each activities performed. For each individual it will return the total of left and right hand grasp (and eventually other data like "bimanual" for example). The HI and the z-score is also returned for each individual with the corresponding p-value and each individual is classified as right handed (R), left handed (L) or ambiguous (A). These results can be saved directly in a .csv file (see "savetable" below).

laterAFCM
(Package: Laterality) :
laterAFCM: this function calculates disjunctive table, Burt table and contributions for multiple correspondence analysis (MCA).
Calculates disjunctive table, Burt table and contributions for MCA.
laterhist
(Package: Laterality) :
laterhist: this function plots an histogram of the different type of grasp (Left, right, bimanual...) for each kind of activity.
Counts the number of occurences of each type of grasp and plot the corresponding histogram for each task performed.
HIndiv
(Package: Laterality) :
HIndiv: this function calculates the Handedness Index of each individual for each activity and plots the corresponding histogram.
Calculates the Handedness Index of each individual regarding to each task performed and plots the corresponding histogram for each individual. The results can be saved in a .csv file.
Calculates handedness index (HI) and z-score for each individual and each task performed. It plots barplots of the different type of grasp (Left, right, bimanual...) for each kind of activity. It plots also the Handedness Index of each individual for each activity. The mean Handedness Index and the absolute HI and absolute mean HI can be calculated. Finally some functions (based on ade4-package functions) calculates disjunctive table, Burt table and contributions for MCA and then plots multiple correspondence analysis graphs.
HIndivabs
(Package: Laterality) :
HIndivabs: this function calculates the absolute Handedness Index of each individual for each activity and plots the corresponding histogram.
Calculates the absolute Handedness Index of each individual regarding to each task performed and plots the corresponding histogram for each individual. The results can be saved in a .csv file.
