CRAN release: 2021-07-12

  • Changed gt package usage in a vignette due to deprecated gt function
  • Replied to minor comments from CRAN reviewer (no functionality impact)
  • Minor update to DESCRIPTION citing Jennison and Turnbull reference

gsDesign 3.2.0 (January, 2021)

CRAN release: 2021-03-13

  • Substantially updated unit testing to increase code coverage above 80%
  • Updated error checking messages to print function where check fails
  • Removed dependencies on plyr packages
  • Updated github actions

gsDesign 3.1.1 (May, 2020)

CRAN release: 2020-05-07

  • Vignettes updated
  • Added hGraph() to support ggplot2 versions of multiplicity graphs
  • Eliminated unnecessary check from sequentialPValue
  • Targeted release to CRAN
  • Removed dependencies on reshape2, plyr
  • Updated continuous integration
  • Updated license

gsDesign 3.1.0 (April, 2019)

  • Addition of pkgdown web site
  • Updated unit testing to from RUnit to testthat
  • Converted to roxygen2 generation of help files
  • Converted vignettes to R Markdown
  • Added Travis-CI and Appveyor support
  • Added sequentialPValue function
  • Backwards compatible addition of spending time capabilities to gsDesign and gsSurv

gsDesign 3.0-5 (January, 2018)

  • Registered C routines
  • Fixed “gsbound”
  • Replaced “array” by “rep” calls to avoid R CMD check warnings

gsDesign 3.0-4 (September, 2017)

  • First Github-based release
  • Cleaned up documentation for nBinomial1Sample()
  • Updated documentation and code (including one default value for an argument) for nBinomial1Sample() to improve error handling and clarity
  • Updated sfLDOF() to generalize with rho parameter; still backwards compatible for Lan-DeMets O’Brien-Fleming

gsDesign 3.0-3

  • Introduced spending time as a separate concept from information time to enable concepts such as calendar-based spending functions. The only user function changed is the gsDesign() function and the change is the addition of the parameters usTime and lsTime; default behavior is backwards compatible.

gsDesign 3.0-2 (February, 2016)

  • Simplified conditional power section of gsDesignManual.pdf in doc directory
  • Corrected basic calculation in gsCP()
  • Eliminated deprecated ggplot2 function opts()

gsDesign 3.0-1 (January, 2016)

CRAN release: 2016-02-01

  • More changes to comply with R standards (in NAMESPACE - importFrom statements - and DESCRIPTION - adding plyr to imports) ensuring appropriate references.
  • Deleted link in documentation that no longer exists (gsBinomialExact.Rd).
  • Last planned RForge-based release; moving to Github.

gsDesign 3.0-0 (December, 2015)

  • Updated xtable extension to meet R standards for extensions.
  • Fixed xtable.gsSurv and print.gsSurv to work with 1-sided designs
  • Update to calls to ggplot to replace show_guide (deprecated) with show.legend arguments where used in ggplot2::geom_text calls; no user impact
  • Minor typo fixed in sfLogistic help file
  • Cleaned up “imports” and “depends” in an effort to be an R “good citizen”
  • Registered S3 methods in NAMESPACE

gsDesign 2.9-4

  • Minor edit to package description to comply with R standards

gsDesign 2.9-3 (November, 2014)

CRAN release: 2014-11-10

  • Added sfTrimmed as likely preferred spending function approach to skipping early or all interim efficacy analyses; this also can adjust bound when final analysis is performed with less than maximum planned information. Updated help(sfTrimmed) to demonstrate these capabilities.
  • Added sfGapped, which is primarily intended to eliminate futility analyses later in a study; see help(sfGapped) for an example
  • Added summary.spendfn() to provide textual summary of spending functions; this simplified the print function for gsDesign objects
  • Added sfStep() which can be used to set an interim spend when the exact amount of information is unknown; an example of how this can be misused is provided in the help file
  • Fixed rounding so that gsBoundSummary, xtable.gsSurv and summary.gsDesign are consistent for gsSurv objects
