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

• 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 0.1.0

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.
