[R] R equivalent of S+SeqTrial?

Does anyone know of an R package that is equivalent of S+SeqTrial for
analysis of clinical trials using group sequential methods? Thanks.

I don't know that there are fully functional equivalents, but you might
want to look at the following:

1. The GroupSeq package on CRAN:

  http://cran.r-project.org/src/contrib/Descriptions/GroupSeq.html


2. The ldBands() function in Frank Harrell's Hmisc package on CRAN:

  http://biostat.mc.vanderbilt.edu/s/Hmisc/html/ldBands.html

This also requires the ld98 executable, which is available from:
