v0.7.4

• Added new safety layout functions:
  • count_abnormal_by_marked tabulates marked laboratory abnormalities.
  • summarize_patients_exposure_in_cols tabulates patient counts and sum of exposure across all patients.
• Enhanced mmrm related functions for fitting models without arm variable.
• Updated cox_regression to work without covariates. Also in case of interaction model summary, p-values for main effect coefficients are no longer displayed.
• Descriptive statistics returned by summarize_vars now include quantiles. In addition, summarize_vars now accepts the the control function control_summarize_vars to specify details about confidence level for mean and median and quantile details. The control argument replaces conf_level.
• Added var_labels and show_labels arguments to count_occurrences_by_grade.
• Changed indent argument in append_varlabels to accept non-negative integer to represent the indent space defined by user. Previous calls with Boolean indent will do an integer conversion and produce a warning.
• Corrected tabulate_survival_subgroups and related survival forest plot functions to use total number of events, instead of observations, as default for scaling the symbol sizes in the plot. (The user might still use total number of observations manually if they wish to do so.)
• Helper function h_adsl_adlb_merge_using_worst_flag will now correctly impute BTOXGR for missing visits.
• Deleted count_abnormal_by_worst_grade_by_baseline and its related statistic and analysis functions as lab abnormality tables can be achieved using a simpler design.
• Switched data in examples to use scda instead of random.cdisc.data package.
