vertex.hemis: Return the proper hemi string ('lh' or 'rh') for each vertex.

In dfsp-spirit/nitools: Managing and Visualizing Brain Surface Data

Return the proper hemi string ('lh' or 'rh') for each vertex.

Description

Return the proper hemi string ('lh' or 'rh') for each vertex.

Usage

vertex.hemis(surface, vertices)

Arguments

surface	hemilist of surfaces or a single integer which will be interpreted as the vertex count of the left hemisphere.
vertices	vector of positive integers, the query vertex indices. Can be in range 1..(nv(lh)+nv(rh)), i.e., across the whole brain.

Value

vector of character strings, each string is 'lh' or 'rh'.

Note

It is not checked in any way whether the vertex indices are out of bounds on the upper side (higher than the highest rh vertex index).

Examples

  vertex.hemis(100L, vertices=c(99L, 100L, 101L));
