Extract Time Series from Surface Vector

Source: R/neuro_surface.R
series-methods.Rd

Extracts time series data from specific vertices in a surface vector.

Usage

# S4 method for class 'NeuroSurfaceVector,numeric'
series(x, i)

# S4 method for class 'NeuroSurfaceVector,integer'
series(x, i)

# S4 method for class 'NeuroSurfaceVector,ROISurface'
series(x, i)

# S4 method for class 'NeuroSurface,numeric'
series(x, i)

Arguments

x

the object to extract the series from

i

the indices of the series to extract

Value

A matrix with time points in rows and the requested vertices in columns, i.e. T x length(i) for a NeuroSurfaceVector with T time points, matching the neuroim2::series() convention for NeuroVec. The orientation does not depend on whether i is stored as integer or double; a single index gives a T x 1 matrix. For a NeuroSurface (one value per vertex) the result is a 1 x length(i) matrix.
