gst 0.4.0

First CRAN release.

Breaking changes

• The Shiny module functions (esWidgetUI(), esWidgetServer(), power2_ui(), power2_sever(), gstTippingPoint_ui()) and app_sys() are no longer exported. They are internal to gst_power_app() and make_forestplot_app(), which are unchanged
• sim_power() now uses one core by default (ncore = 1L, previously 4) and no longer prints progress or timing. Set verbose = TRUE for progress messages

Minor changes

• get_n() documentation now states that it returns the sample sizes n0 and n1
• Every exported function documents its return value and has a runnable example
• Title and Description rewritten, with references to O’Brien (1984) and Luo et al. (2025)
• Removed the non-standard pdr role from the maintainer’s Authors@R entry
• License field changed to the standard Apache License (== 2.0); the license itself is unchanged
• Requires R >= 4.1.0 (the package uses the native pipe)
• Import only the needed ggplot2 and plotly functions, which removes the last_plot() import warning
• Use TRUE/FALSE instead of T/F throughout
• Removed the empty wei_lachin() placeholder
• Smaller vignette screenshot

gst 0.3.1

Minor Changes

• Point the package site, issue links, and in-app help links at the xni7/gst fork
• Cite Luo et al. (2025) in the reference vignette and in obt(), and remove the private white-paper link
• Record Xiao Ni as the maintainer contact
• Reword the sartheme() title; the function name and app colors are unchanged

gst 0.3.0

Last release on GitLab. gst will move to GitHub for all future development

Major Changes

• Added obrien_plus() to compute power for joint endpoints and any individual endpoint

• Added obt() to perform O’Brien truncated closed testing

Minor Changes

• Improved functionality and UI of make_forestplot_app() and gst_power_app()

gst 0.2.0

Major Changes

• Custom columns feature with option to reorder/resize columns

• Improved downloads: preview/adjust the image in real-time

Minor Changes

• Improved R code generator: more robust to future changes; added options to remove gst dependency, ‘copy to clipboard’, or ‘download’

• Added dynamic default parameters based on input data

• Axes: customize tick marks; toggle symmetry on/off

• Arrows: customize/reverse arrow labels

Bug Fixes

• Fixed infinite loop when selecting ‘Number of Trees’

• Fixed issue with invert column when copy/pasting data

gst 0.1.0

Initial release.

Includes functions to launch two shiny applications:

• GST Power App: gst_power_app()
• Make Forestplot App: make_forestplot_app()

GST Power App can be used to run power and sample size calculations for the Global Statistical Test under a variety of scenarios. Additional details can be found in the vignette.

Make Forestplot App allows users to easily generate a forestplot by uploading data, copy/pasting from a spreadsheet, or manually typing. The resulting plot can be resized and visually customized in a variety of ways. Also included are options to handle endpoints with inverted directionality and different scales. See the vignette for additional details.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
