• {tern} is a dependency but now that the qenv doesn't inherit the environment from the parent.env it must be loaded or functions prefixed to make code fully reproducible in a fresh session (without previous loading anything.
  • append_varlabels
  • summarize_num_patients
  • count_occurrences
  • count_occurrences_by_grade
  • score_occurrences_cont_cols
  • summarize_num_patients
  • summarize_occurrences_by_grade
  • extract_survival_subgroups
  • combine_levels
  • tabulate_survival_subgroups
  • g_forest
  • extract_rsp_subgroups
  • tabulate_rsp_subgroups
  • g_km
  • control_surv_timepoint: Thre is one call within do.call("control_surv_timepoint" that I didn't prefix it because it would fail, we might need to load the package for that module.
  • estimate_multinomial_response
  • estimate_odds_ratio
  • estimate_proportion_diff
  • test_proportion_diff
  • summarize_coxreg
  • fit_logistic
  • default_na_str
  • control_coxreg!
  • control_incidence_rate
  • estimate_incidence_rate
  • estimate_proportions
  • summarize_ancova
• {rtables} isn't loaded by default: prefixing for:
  • sort_at_path
  • split_fun
  • drop_split_levels
  • add_overall_level
  • trim_levels_to_map
  • keep_split_levels
• {formatters} is not available on a fresh session for:
  • obj_label
• Modules tm_t_ancova and tm_t_mmrm depended on the option set on .onLoad for TMC. Instead of removing the call for the default via default_na_str the modules set the default via tern::set_default_na_str
• Modules tm_t_mmrm, tm_g_barchart_simple, tm_t_g_forest_tte and tm_t_coxreg now use the label instead in the modal on "Show R Code" to be consistent with other modules.
