Skydivide is a package for doing divide-and-conquer MCMC in phylodynamics. User first split the genomic data into disjoint subsets, run MCMC using each subsets in BEAST separately. Then skydivide combines all the outputs of BEAST and reconstructs the effective population size.
You can install the development version of skydivide from GitHub with:
# install.packages("devtools")
devtools::install_github("liusf15/skydivide")
The example can be found in the vignette
