Resample timeseries

Description

Resample single- or multi-variate time series using linear or nearest neighbour interpolation

Usage

  resample(raw, rawTime, time, stop, type = 1)	

Arguments

raw	stop-by-3 matrix with raw values of x, y and z.
rawTime	vector with stop elements of raw time.
time	array with required time points.
stop	Number of rows in raw
type	integer to indicate type of interpolation, 1=linear, 2=nearest neighbour

Examples

  raw = cbind(1:10, 1:10, 1:10)
  rawTime = seq(0.1, 1, by = 0.1)
  time = seq(0.15001, 1.05001, by = 0.1)
  stop = 10
  dat_lin = resample(raw, rawTime, time, stop, type = 1)
