derivativeTransform {RTCA} | R Documentation |
Derivative transform of RTCA object, returning the change rate of cell impedance
derivativeTransform(object)
object |
An object of |
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.
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
.
