Subsets a bammdata object. Returns a bammdata
object after extracting a specified set of samples from the posterior.
Usage
subsetEventData(ephy, index)
Arguments
ephy
An object of class bammdata.
index
A vector of integers corresponding to samples to be extracted
from the posterior distribution of shift configurations included in
the bammdata object.
Details
This will result in an error if you attempt to access samples
that do not exist in the ephy data object. For example, if your
bammdata object includes 100 samples from a posterior
distribution sampled with BAMM, you can only attempt to subset
with index values 1:100.
