## FreesearchR 26.1.2

Rebuild 26.1.1

## FreesearchR 26.1.1

FIX Two bugs in the “modify factor levels” module was fixed, which would print wrong button labels and save wrong data if not selecting to save as new factor.

TRANLATIONS DA and SW translations are updated. This was mostly done using machine translations and will be reviewed in the coming months.

## FreesearchR 25.12.7

NEW The landing page was overhauled for a nicer intro and better overview with focus on the basic functions.

## FreesearchR 25.12.6

NEW Export missingness table directly.

NEW Updated and slightly extended list of allowed operators for new variable creation.

FIX The exported MS Word documents prompts a warning. The codebase now includes a fix, but it only works running locally, but was disabled.

## FreesearchR 25.12.5

NEW Added option to add pairwise differences in discriptive table.

## FreesearchR 25.12.4

Republish 25.12.3

## FreesearchR 25.12.3

NEW Extended missingness evaluation to include two different approaches. Docs will catch up and video tutorials are coming.

## FreesearchR 25.12.2

FIX Fixed hanging interface when splitting strings.

NEW New option to shorten character variables to the first N words or characters. Shortening by characters could be useful working with eg. ICD-10 diagnostic codes.

## FreesearchR 25.12.1

NEW Option to edit factor label names in the “New factor” pop-up. This allows for easier naming for tables, but also to combine levels. A new variable is appended to the dataset if label names are changed. Code is now also exported.

FIX Fixes a bug, where white space in code exported was removed. Now a little too many spaces are included. Fine tuning continues.

NEW Easily copy code by just clicking “copy” in code blocks.

## FreesearchR 25.11.2

NEW Vignettes were moved to the FreesearchR project knowledge base. This was mainly to ease rendering and allow quick and easy updates as well as future translations.

## FreesearchR 25.11.1

NEW Added option to select extensive baseline table selecting between “Minimal” (current) or “Extensive” which adds mean/sd and min/max as well as plots all levels also for dichotomous variables.

## FreesearchR 25.10.5

NEW New character/text split function available. A selection of delimiters are recognised and selectable. Function only available if splittable variables are present.

NEW Distribution plotting for factors have been much improved including two new bar plot styles and removing options better suited for continuous data.

These were the last major functions to be implemented after workshops at Jitimai in Zanzibar City, Zanzibar during October 2025.

## FreesearchR 25.10.4

NEW Two new options to create new simplified factors from factors. The “top” option will keep only the top N levels, while the “bottom” option will combine all levels occurring below set percentage.

NEW The “New factor” function received some updates to include detailed information on the methods for creating new factors.

LANGUAGE Updated Swahili strings. All Danish strings are translated. New languages are on track.

## FreesearchR 25.10.3

NEW Improvements to translations with more strings having been translated. Nearing completion of marking strings for translation, which means (almost) the complete interface is now translatable.

## FreesearchR 25.10.2

NEW Improvements to translations with more strings having been translated.

NEW More detailed label for the stacked horizontal bar plot.

NEW Better .rds import that will import the first element as data.frame if a list-type element is supplied.

NEW A limit to the imported dataset size was added to ensure performance on hosted version. The data is limited to 100.000 cells by dropping rows to fit. The vast majority of users will never experience this capping, but adds a layer of security and stability to the hosting framework.

## FreesearchR 25.10.1

NEW Improvements to translations with more strings having been translated.

NEW Sample data has been filtered to only include a few select packages (NHANES and stRoke).

NEW Missings evaluations slightly tweaked to include bold significant p-values for easier overview.

## FreesearchR 25.9.2

NEW Improvements to translations with more strings having been translated.

The Euler visualisation option has been limited to only plot dichotomous variables. This is also what makes the most sense.

## FreesearchR 25.9.1

NEW Language has been revised to make the app more accessible and easier to understand.

NEW Foundations for introducing an internationalised UI has been introduced. Initial and very rudimentary translation for Danish and Swahili is included. Other languages can be added as well.

NEW Alerts as to guide on select important steps and aspects are introduced. This is expected to expand.

## FreesearchR 25.8.2

- NEW Including the NHANES dataset for experimentation.

- BUG Improved JS to correctly handle menu drop downs on mobile devices

- DOCS Updated “Prepare > Overview” to “Prepare > Overview and filter” to better reflect options.

## FreesearchR 25.8.1

- NEW improved the use of `wrap_plot_list()` to pass on additional arguments to `patchwork::wrap_plots()` and allowed to specify axes to align in `align_axes()`.
- FIX fixed axis text printed in Euler diagrams

## FreesearchR 25.7.2

- FIX refining hiding drop downs. All JavaScript is now in separate file. Coded with GAI help from claude.ai.

- FIX refined iconography and navigation

- FIX updated intro and docs.

## FreesearchR 25.7.1

- NEW UI overhaul and navigation update. The interface is simplified to clearly show the relationship between panels and sub-items by abandoning multiple levels on panel to instead show a drop-down menu. This also results in simplified sidebar menus with room to add more controls in the future.

## FreesearchR 25.6.4

The app is now also published as a docker container. See the README for instructions. It is mainly to use for hosting the app. Work is ongoing to publish a true standalone app, preferably for both Windows and MacOS.

- FIX improved plot labels.

## FreesearchR 25.6.3

- NEW Introducing more options to evaluate missing observations. Inspired by the [visdat()] function from the {visdat} package, a specialised function has been introduced to easily visualise data classes and missing observations in the data set. This highly increases the options to visually get an overview of the data and to assess the pattern of missing data. Also under Evaluate, a comparison module has been introduced to compare the distribution of observations across variables depending on the missing vs non-missing in a specified variable.

- FIX The REDCap import module has been updated visually and the PAI token is now hidden as a password. This module should still only be used when running locally if you are accessing sensitive data.

- minor rewordings and updated UI.

## FreesearchR 25.6.2

- FIX Added warning about only using REDCap with sensitive data running locally. THis applies to all data actually. Considering taking REDCap out in hosted version. Standalone app is in the works.

- FIX Reworded the completeness filter to be on missingness, as this is a more commonly used concept.

- FIX Improved layout around data filters to improve usage.

- FIX Regression table in report respects inclusion of p-values or not.

## FreesearchR 25.6.1

- FIX big not allowing to browse data

- FIX caught the last bugs when initiating the creation of new variables

## FreesearchR 25.5.6

- FIX note on max file size of 5 mb

- FIX added a banner to the dev version on shinyapps.io

- FIX updated intro text

## FreesearchR 25.5.5

- FIX several minor bugs and polish

- FIX include/exclude p-values in regression table.

## FreesearchR 25.5.4

- FIX correctly omit NAs in `data_type()` call

- FIX omit NAs when plotting Euler diagrams.

- FIX print correct labels in horizontal stacked bars.

- FIX initial app load should feel faster.

## FreesearchR 25.5.3

- FIX a little polish on the data import

- FIX polished REDCap import and new code to reference the `REDCapCAST::easy_redcap()` function.

- FIX updated documentation to reflect new private hosting on a Hetzner server in Germany.

## FreesearchR 25.5.2

- FIX: correct export of plots. The solution in the last version broke more than it solved.

- NEW: added simple loading animation.

A privately hosted version is now live on app.freesearchr.org. For now, it is hosted on Hetzner with Yunohost.

## FreesearchR 25.5.1

- FIX: correct export of single variable plot.

- NEW: Include app version in report for reference.

- IMPROVED: analyses results are reset on data change

- NEW: app usage tracking only in hosted app. README updated to reflect.

## FreesearchR 25.4.4

Minor updates in docs and easier citation.

## FreesearchR 25.4.3

- NEW: Added a variables type filter to easily exclude unwanted types. This also includes having data type rather than data class in the summary table. Will evaluate. Types are a simpler, more practical version of the R data class to easy interpretation.

- NEW: A logo is here! It should emphasize the underlying reliance on R while also inspire to explore.

- IMPROVED: docs are updated and much more comprehensive. They will be continuously updated.

Polishing and moved hosted app to new address to fully reflect name change: https://agdamsbo.shinyapps.io/FreesearchR/

## FreesearchR 25.4.2

Polished and simplified data import module including a much improved REDCap import module.

- CHANGE `default_parsing()` now ensure unique variable names.

- NEW Working code output for all major modules including import, modifications, filter, evaluation, plotting and regression. And it is nicely formatted!

- NEW The basics of a “Getting started”-vignette is done, and can be expanded on later.

## FreesearchR 25.4.1

Focus is on polish and improved ui/ux.

Updating project name to FreesearchR, with renamed repository. Graphics are coming. This may introduce some breaking chances for others calling or installing the package. No additional future changes are planned. A complete transition is planned before attending and presenting a poster at the European Stroke Organisation Conference 2025 in May.

Testing file upload conducted and improved.

Working on improving code export. This is very difficult to get perfect. Initial focus is on extracting enough to be able to learn from it.

Regression calculations, plots, and checks have been improved and moved to standalone module.

Data overview/modifications has been simplified slightly.
