Changelog • rpact.cloud

RPACT Cloud 2.8.1

Saving Designs
- Sessions (including all designs) can now be downloaded as a file and restored via an HTML link
- Sessions can be bookmarked in the browser, preserving all designs
- All designs are automatically restored after a session timeout (just reload the page, e.g. with the F5 key, when the app is greyed out)

Comparison Tool
- Added a Comparison Tool Help page to the comparison tab
- Comparison tables are now generated with the flextable package
- Added filters for relevant parameters
Survival Design Simulation (Two Groups)
- Users can define the number of raw datasets per stage (maxNumberOfRawDatasetsPerStage)
- Raw data can be exported as an Excel file
Standard Deviation
- For two-armed trials, it is possible to specify the standard deviations separately, i.e., different standard deviations for group 1 and 2 can be defined.

Improved performance by replacing all conditional panels with a server-side rendering solution
Several design comparison settings have been moved to a central settings tab on the right for easier access and usability

Installation Qualification & Quality Assurance
- Added User Requirements Specification (URS). Details: https://docs.cloud.rpact.com/articles/urs.html
- Perform installation qualification directly in the System Status section while the app is running.
- Download qualification reports as HTML or PDF.
- Enhanced UX with a progress spinner and real-time status updates.
Session Timeout Handler
- Introduced session timeout logic with an environment variable fallback.
- Display remaining session time with conditional formatting based on time left.
Table Rendering Improvements
- New options in the project comparison UI to toggle rounding and set decimal precision via checkbox and select inputs.
- Dynamically enable or disable related UI controls (roundingEnabled, digits) based on user selections.
- Refactored roundNumericTableColumnsBeforeRendering to return both the modified data frame and the list of numeric columns, allowing precise rendering control.

Report Legend Position
- Added a drop-down menu to select the legend position in generated reports.
Markdown Rendering
- Switched from markdown::markdownToHTML to markdown::mark_html for more flexible resource embedding.
Internal Utilities
- Documented utility functions (appendTabItem, closeTabItem, getPreConfigurationFromURL) for improved code clarity.
- Strengthened validation logic to robustly handle edge cases (e.g., numeric and grouping values).
