In bbuchsbaum/neurosurf: Data structures and visualization for surface-based neuroimaging data

Create an instance of class ROISurfaceVector

Description

Create an instance of class ROISurfaceVector

Usage

ROISurfaceVector(geometry, indices, data)

Arguments

geometry	the parent geometry: an instance of class SurfaceGeometry
indices	the parent surface indices
data	the data values, a matrix

Value

an instance of class ROISurfaceVector

Examples

verts <- matrix(c(0,0,0,
                  1,0,0,
                  0,1,0), ncol=3, byrow=TRUE)
faces <- matrix(c(1,2,3), ncol=3, byrow=TRUE)
geom <- SurfaceGeometry(verts, faces, "lh")

vec <- matrix(c(0.5, 1.5), nrow=1)
ROISurfaceVector(geom, c(1L,2L), vec)

try(ROISurfaceVector(geom, c(1L,4L), vec))
try(ROISurfaceVector(geom, c(1,2.5), vec))
