Calculate differences between stages

Usage

calc_Deltas(
  .tilde_data = NULL,
  key_analysis_vars = ReboundTools::key_analysis_vars,
  rebound_stages = ReboundTools::rebound_stages,
  .all_vars = "all_vars"
)

Arguments

.tilde_data: A data frame containing rebound calculations, original data, star data, hat data, and tilde data, likely calculated by calc_tilde().
key_analysis_vars: See ReboundTools::key_analysis_vars.
rebound_stages: See ReboundTools::rebound_stages.
.all_vars: A column names used internally for all variables. Default is ".all_vars".

Value

.tilde_data with additional columns containing all possible difference terms.

  calc_orig() %>% 
  calc_star() %>% 
  calc_hat() %>% 
  calc_bar() %>%
