s_diff: Calculate slopes from time points and time series matrix.

In SPEM: S-system parameter estimation method

Description

This function allows users calculate slopes from time points and time series data.

Usage

## S4 method for signature 'ExpressionSet'
s_diff(TS_eSet)

Arguments

TS_eSet

Time series data in ExpressionSet class. assayData: Matrix with n metabolite in row and m time points in column. phenoData: phenoData type. The sample data.frame should include the label "time", which represents the values of time points.

Value

This function directly return a slope matrix.

Methods
