This function will set all values in morphdata which are *not* part of the labeldata to NA (or whatever is specified by 'masked_data_value'). This is typically used to ignore values which are not part of the cortex (or any other label) during your analysis.
apply.labeldata.to.morphdata(morphdata, labeldata,
masked_data_value = NA)numerical vector, the morphometry data for one hemisphere
integer vector. A label as returned by [subject.label()].
numerical, the value to set for all morphometry data values of vertices which are *not* part of the label. Defaults to NA.
numerical vector, the masked data.
