arfcorrelation-class: Class "arfcorrelation"

In arf3DS4: Activated Region Fitting, fMRI data analysis (3D).

Description

Object of class "arfcorrelation" hold information on correlations between regions of the spatial model. The functions fitConnectivity and roiConnectivity have as output an object of class "arfcorrelation".

Objects from the Class

Objects can be created by calls of the form new("arfcorrelation", ...).

Slots

timebyreg:

Trial-by-trial amplitude estimates per region (time x nreg)

corr:

Correlation matrix.

corr.pval:

P-values of the correlations

pacorr:

Partial correlation matrix (corrected for all other regions).

pacorr.pval:

P-values of partial correlations

num.corr:

Number of correlations tested.

Methods

Standard arf3DS4 accessor and replacement functions can be used to access and replace slots.

access

.classname.slotname(object)

replace

.classname.slotname(object)<-

In this case classname is "arfcorrelation" and slotname is for example "correlation". So to access the "correlation" slot of an r-object "arfcor" (of class "arfcorrelation") type .arfcorrelation.correlation(arfcor).
