Convert onsets to global timing

Generic accessor for converting block-wise onsets to global onsets.

Usage

global_onsets(x, ...)

# S3 method for class 'sampling_frame'
global_onsets(x, onsets, blockids, ...)

Arguments

x

Object describing the sampling frame

...

Additional arguments passed to methods

onsets

Numeric vector of onset times within blocks

blockids

Integer vector identifying the block for each onset. Values must be whole numbers with no NAs.

Value

Numeric vector of global onset times

Examples

# Convert block-relative onsets to global timing
sframe <- sampling_frame(blocklens = c(100, 120), TR = 2)
global_onsets(sframe, onsets = c(10, 20), blockids = c(1, 2))
#> [1]  10 220
