interpolationTransform: TRANSFORM RTCA DATA WITH INTERPOLATION

In RTCA: Open-source toolkit to analyse data from xCELLigence System (RTCA)

Description

Interpolate RTCA data

Usage

interpolationTransform(object, interval=0.01, method=c("linear","constant","fmm","periodic","natural", "monoH.FC"))

Arguments

object	An RTCA object
...	other parameters, interval and method are implemented, see below
interval	numeric, the interval between interpolated points, set to 0.01 by default
method	character, specifying the method for interpolation, “linear” by default (for linear interpolation). Allowed options are: “linear” and “constant” for approx interpolation, and “fmm”, “periodic”, “natural” and “monoH.FC” for cubic spline interpolation

Details

Since most RTCA experiements record the experiments in the irregular time-series, sometimes however it is desired to have regular intervals. interpolationTransform interpolate between data points to estimate results of regular intervals.

Two classes of interpolations are supported by now: linear (using approx) and cubic spline (spline) interpolation. By default linear interpolation is used.

Value

An interpolated object of RTCA.
