Hi, I found this post from 6 years ago about this: https://stat.ethz.ch/pipermail/r-help/2001-May/012800.html Basically, I'd like to find an R implementation of the multimodality test in the book "Introduction to the Bootstrap" by Efron and Tibshirani. There is an R package bootstrap which is the package to go with the book, but it does not seem to implement the multimodality test. I found this post to the S mailing list giving an implementation in development: http://www.biostat.wustl.edu/archives/html/s-news/2000-06/msg00038.html but I'm not sure about it. Anyway, if anyone knows where I can find an R implementation please let me and the list know. thanks, Andrew Smith
