extract.equivalent_shifts takes an object of class
equivalent_shifts, result of function equivalent_shifts,
and returns the shifts of root values for a given trait.
"extract"(x, trait = 1, what = c("shifts_values", "root_values"), ...)equivalent_shifts, result of
function equivalent_shiftswhat = "shifts_values") or
the root (what = "root_values") for the trait for each equivalent
configuration. Each column is one configuration.
