assignStrainTraits: Internal function to assign stochastic strain traits

In HelenKettle/microPop: Modelling Microbial Populations

Description

Produces a random distribution of trait values where the mean is groupVal and the range is determined by percentRange (if not pHtrait) and by maxPHshift if it is the pHtrait (see strainOptions)

Usage

assignStrainTraits(numStrains, groupVal, strainOptions,
  parName = "unspecified param", pHtrait = FALSE)

Arguments

numStrains	Integer. Number of strains per group
groupVal	Scalar. Group parameter value i.e. the mean parameter value
strainOptions	List containing 'distribution' i.e. the shape of the distribution ('normal' or 'uniform'). If it is not for a pH trait and the distribution is 'normal' then its std dev is groupVal*percentRange/200, if distribution is 'uniform' then its range is groupVal*(1 +/- percentRange/100). For a pH trait, 'maxPHshift' is the max shift in pH units and 'normal' has std dev = maxPHshift/2, and 'uniform' distribution has range groupVal +/- maxPHshift;
parName	Name of parameter. This is only used to help with error catching
pHtrait	TRUE/FALSE whether or not trait is the pH trait.

Value

vector of values for each strain for one parameter
