astimedData: Convert a time series object to a timed data matrix

In smfsb: Stochastic Modelling for Systems Biology

Description

This function converts a time series object to a timed data matrix, similar to that produced by simTimes. The main purpose is for passing data to the function pfMLLik, which expects data encoded in this format.

Usage

as.timedData(timeseries)

Arguments

timeseries

An R timeseries object, such as produced by the functions ts or simTs.

Value

An R matrix object with row names corresponding to observation times, similar to that produced by simTimes.

Examples

truth=simTs(c(x1=50,x2=100),0,20,2,stepLVc)
simData=truth+rnorm(prod(dim(truth)),0,5)
timedData=as.timedData(simData)
print(timedData)
