| Summary : Selection Response Analysis
|
Description :
Artificial selection through selective breeding is an efficient way to
induce changes in traits of interest in experimental populations. This
package (sra) provides a set of tools to analyse artificial-selection
response datasets. The data typically feature for several generations
the average value of a trait in a population, the variance of the
trait, the population size and the average value of the parents that
were chosen to breed. Sra implements two families of models aiming at
describing the dynamics of the genetic architecture of the trait during
the selection response. The first family relies on purely descriptive
(phenomenological) models, based on an autoregressive framework. The
second family provides different mechanistic models, accounting e.g.
for inbreeding, mutations, genetic and environmental canalization, or
epistasis. The parameters underlying the dynamics of the time series
are estimated by maximum likelihood. The sra package thus provides (i)
a wrapper for the R functions mle() and optim() aiming at fitting in a
convenient way a predetermined set of models, and (ii) some functions
to plot and analyze the output of the models.
