News

3.0-1, January, 2016

• 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).

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 geom_text (function from ggplot2 package) 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

2.9-4

• Minor edit to package description to comply with R standards

2.9-3, November, 2014

• 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
