merge.epiICM: Merge Model Simulations Across epiICM Objects

Description

This function merges data from two independent epiSPM simulations.

Usage

## S3 method for class 'epiICM':
merge(x, y, ...)

Arguments

x

an EpiModel object of class epiICM.

y

another EpiModel object of class epiICM, with the identical model parameterization as x.

...

additional arguments required by generic merge method, but not used.

Details

The purpose of this generic merge function is to facilitate analysis of multiple simulations of epiICM class models that may have been simulated under different function calls, but where the model parameterization between the two calls is exactly the same. Such a situation would occur when one runs sets of simulations in parallel across computing clusters for efficency.

Note that this merge function does not work the same as the default merge in allowing for a combined object where the structure differs between the individual elements: instead, the function checks that objects are identical in model parameterization in every respect except number of simulations.

Examples

x <- epiICM(type="SI", s.num=1000, i.num=100,
            trans.rate = 0.2, act.rate = 0.8,
            nsteps = 10, nsims = 3)

y <- epiICM(type="SI", s.num=1000, i.num=100,
            trans.rate = 0.2, act.rate = 0.8,
            nsteps = 10, nsims = 2)

z <- merge(x, y)
x$i.num
y$i.num
z$i.num
