• beastier runs BEAST2
• mauricer: install BEAST2 packages
• tracerer pastes BEAST2 output (.log, .trees, etc) files.

# Obtain an example log file its name
filename <- get_tracerer_path("beast2_example_output.log")

# Parse that log file
beast_log_full <- parse_beast_log(filename)

# Remove the burn-in
beast_log <- remove_burn_ins(
  beast_log_full,
  burn_in_fraction = 0.1
)

# Calculates the effective sample sizes of all parameter estimates
esses <- calc_esses(beast_log, sample_interval = 1000)
