      Branch naming convention

      Suppose your changes are related to a current issue in the current project; please name your branch as follows: <issue_id>_<short_description>. Please use underscore (_) as a delimiter for word separation. For example, 420_fix_ui_bug would be a suitable branch name if your change is resolving and UI-related bug reported in issue number 420 in the current project.

      If your change affects multiple repositories, please name your branches as follows: <issue_id>_<issue_repo>_<short description>. For example, 69_awesomeproject_fix_spelling_error would reference issue 69 reported in project awesomeproject and aims to resolve one or more spelling errors in multiple (likely related) repositories.

monorepo and staged.dependencies - -

+

Sometimes you might need to change upstream dependent package(s) to be able to submit a meaningful change. We are using staged.dependencies functionality to simulate a monorepo behavior. The dependency configuration is already specified in this project’s staged_dependencies.yaml file. You need to name the feature branches appropriately. This is the only exception from the branch naming convention described above.

Please refer to the staged.dependencies package documentation for more details.

Dependency version management

If the code is not compatible with all (!) historical versions of a given dependenct package, it is required to specify minimal version in the DESCRIPTION file. In particular: if the development version requires (imports) the development version of another package - it is required to put abc (>= 1.2.3.9000).

R & package versions

We continuously test our packages against the newest R version along with the most recent dependencies from CRAN and BioConductor. We recommend that your working environment is also set up in the same way. You can find the details about the R version and packages used in the R CMD check GitHub Action execution log - there is a step that prints out the R sessionInfo().

If you discover bugs on older R versions or with an older set of dependencies, please create the relevant bug reports.

We highly recommend that you use the pre-commit tool combined with R hooks for pre-commit to execute some of the checks before committing and pushing your changes.

Automatic digit formatting: The number of digits to display can be automatically determined from the analyzed variable(s) (vars) for certain statistics by setting the statistic format to "auto" in .formats. This utilizes the format_auto() formatting function. Note that only data for the current row & variable (for all columns) will be considered (.df_row[[.var]], see rtables::additional_fun_params) and not the whole dataset.

    • If x is an empty factor, a list is still returned for counts with one element per factor level. If there are no levels in x, the function fails.

    • If factor variables contain NA, these NA values are excluded by default. To include NA values set na.rm = FALSE and missing values will be displayed as an NA level. Alternatively, an explicit factor level can be defined for NA values during pre-processing via df_explicit_na() - the default na_level ("<Missing>") will also be excluded when na.rm is set to TRUE.

row_labels -

row_labels

(character)
as this function works in columns space, usually .labels character vector applies on the column space. You can change the row labels by defining this parameter to a named character vector with names corresponding to the split values. It defaults to NULL and if it contains only one string, it will duplicate that as a row label.

-
do_summarize_row_groups -
+
do_summarize_row_groups

(flag)
defaults to FALSE and applies the analysis to the current label rows. This is a wrapper of rtables::summarize_row_groups() and it can accept labelstr to define row labels. This behavior is not supported as we never need to overload row labels.

-
split_col_vars -
+
split_col_vars

(flag)
defaults to TRUE and puts the analysis results onto the columns. This option allows you to add multiple instances of this functions, also in a nested fashion, without adding more splits. This split must happen only one time on a single layout.

-
imp_rule -
+
imp_rule

(string or NULL)
imputation rule setting. Defaults to NULL for no imputation rule. Can also be "1/3" to implement 1/3 imputation rule or "1/2" to implement 1/2 imputation rule. In order to use an imputation rule, the avalcat_var argument must be specified. See imputation_rule() for more details on imputation.

-
avalcat_var -
+
avalcat_var

(string)
if imp_rule is not NULL, name of variable that indicates whether a row in the data corresponds to an analysis value in category "BLQ", "LTR", "<PCLLOQ", or none of the above (defaults to "AVALCAT1"). Variable must be present in the data and should match the variable used to calculate the n_blq statistic (if included in .stats).

-
cache -

cache

(flag)
whether to store computed values in a temporary caching environment. This will speed up calculations in large tables, but should be set to FALSE if the same rtable layout is used for multiple tables with different data. Defaults to FALSE.

.indent_mods -

.indent_mods

    • This is an experimental implementation of rtables::summarize_row_groups() and rtables::analyze_colvars() that may be subjected to changes as rtables extends its support to more complex analysis pipelines in the column space. We encourage users to read the examples carefully and file issues for different use cases.

    • In this function, labelstr behaves atypically. If labelstr = NULL (the default), row labels are assigned automatically as the split values if do_summarize_row_groups = FALSE (the default), and as the group label if do_summarize_row_groups = TRUE.

        • For factor variables, denom for factor proportions can only be n since the purpose is to compare proportions between columns, therefore a row-based proportion would not make sense. Proportion based on N_col would be difficult since we use counts for the chi-squared test statistic, therefore missing values should be accounted for as explicit factor levels.

Note

These defaults are experimental because we use the names of functions to retrieve the default statistics. This should be generalized in groups of methods according to more reasonable groupings.

Formats in tern and rtables can be functions that take in the table cell value and return a string. This is well documented in vignette("custom_appearance", package = "rtables").

    The variables list needs to include the following elements:

    • arm: Treatment arm variable name.

    • response: The response arm variable name. Usually this is a 0/1 variable.

    • covariates: This is either NULL (no covariates) or a character vector of covariate variable names.

    • interaction: This is either NULL (no interaction) or a string of a single covariate variable name already included in covariates. Then the interaction with the treatment arm is included in the model.

Analysis Functions

+ +

Analyze functions with their corresponding statistics functions and formatted analysis functions.

  • Analyze functions are used in combination with rtables layout functions in the pipeline which creates the table.

  • Statistics functions (denoted by s_ prefix) compute the numbers that are tabulated later. In order to separate computation from formatting, they do not take care of rcell type formatting themselves.

  • Formatted analysis functions (denoted by a_ prefix) have the same arguments as the corresponding statistics functions, and can be further customized by calling rtables::make_afun() on them. They are used as afun in rtables::analyze().

    • This function uses logistic regression for unstratified analyses, and conditional logistic regression for stratified analyses. The Wald confidence interval is calculated with the specified confidence level.

    • For stratified analyses, there is currently no implementation for conditional likelihood confidence intervals, therefore the likelihood confidence interval is not available as an option.

    • When vars contains only responders or non-responders no odds ratio estimation is possible so the returned values will be NA.
