衍生变换的RTCA对象,返回的单元阻抗变化率
用法----------Usage----------
derivativeTransform(object)
参数----------Arguments----------
参数:object
An object of RTCA
一个RTCA的对象

smoothTransform and interpolationTransform for smoothing and interpolating the RTCA data. rgrTransform calculates relative growth rate, which calls derivativeTransform.
smoothTransform和interpolationTransform平滑和插值RTCA数据。 rgrTransform计算相对增长速度,这要求derivativeTransform。

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