DERIVATIVE TRANSFORM OF RTCA OBJECT

Description

Derivative transform of RTCA object, returning the change rate of cell impedance

Usage

derivativeTransform(object)

Arguments

Details

The first derivative of the cell impedance curve measured by RTCA. The derivative of the last time point is estimated by that of the next to last point.

Value

An RTCA object populated with derivative values

smoothTransform and interpolationTransform for smoothing and interpolating the RTCA data. rgrTransform calculates relative growth rate, which calls derivativeTransform.

Examples

require(RTCA)
  
ofile <- system.file("/extdata/testOutput.csv", package="RTCA")
x <- parseRTCA(ofile)

xDeriv <- derivativeTransform(x)
