"xifti"Replace the data in a "xifti" with new data from a data matrix.
newdata_xifti(xifti, newdata, newnames = NULL)The "xifti"
The \(V \ times T\) matrix of data values to replace those
in xifti with. The left cortex vertices should be at the top, right
cortex vertices in the middle, and subcortex vertices at the bottom (when
present). Can also be a length-one vector to set all values equally.
Replace the names in the xifti. If NULL
(default), keep the original names.
The new "xifti"
If the "xifti" has \(V\) grayordinates and T measurements
in total, newdata should be a \(V \times T\) matrix.
