Group sequential design for clinical trials
vignette("ConditionalPowerPlot")
(beb2957, 727fe20, 57394fe).gsBoundSummary()
now has the as_rtf()
method implemented to generate RTF outputs for bound summary tables (@wangben718, #107).plotgsPower()
gets new arguments offset
and titleAnalysisLegend
to enable more flexible and accurate power plots (plottype = 2
) (@jdblischak, #121, #123).dplyr::reframe()
to replace dplyr::summarize()
when performing grouped cumsum()
(@jdblischak, #114)..data
pronoun from rlang with ggplot2::aes()
. This simplifies the code and follows the recommended practice when using ggplot2 in packages (@jdblischak, #124).hGraph()
now uses named guide
argument in the scale_fill_manual()
call to be compatible with ggplot2 3.5.0 (@teunbrand, #115). Note: this function has been deprecated and moved to gMCPLite since gsDesign 3.4.0. It will be removed from gsDesign in a future version. Please use gMCPLite::hGraph()
instead.vignettes("SurvivalOverview")
is updated with more details and minor corrections (@keaven, #126).gsSurv()
and nSurv()
have updated default values for T
and minfup
so that function calls with no arguments will run. Legacy code with T
or minfup
not explicitly specified could break (#105).gsSurvCalendar()
function added to enable group sequential design for time-to-event outcomes using calendar timing of interim analysis specification (#105).as_rtf()
method for gsBinomialExact()
objects added, enables RTF table outputs for standard word processing software (#102).toBinomialExact()
and gsBinomialExact()
: fix error checking in bound computations, improve documentation and error messages (#105).print.gsSurv()
: Improve the display of targeted events (very minor). The boundary crossing probability computations did not change. The need is made evident by the addition of the toInteger()
function (#105).toInteger()
: Fix the documentation and execution based on the ratio
argument (#105).sfPower()
now allows a wider parameter range (0, 15].toInteger()
function added to convert gsDesign
or gsSurv
classes to integer sample size and event counts.toBinomialExact()
function added to convert time-to-event bounds to exact binomial for low event rate studies.as_table()
and as_gt()
methods for gsBinomialExact
objects added, as described in the new "Binomial SPRT" vignette.plot.ssrCP()
, the hat
syntax in the mathematical expression is revised, resolving labeling issues.ggplot2::qplot()
usage replaced due to its deprecation in ggplot2 3.4.0.gsCP()
interim test statistic zi (#63).hGraph()
and suggested using gMCPLite::hGraph()
instead (#70).Depends
to Imports
(#56).See NEWS and what's changed (below).
