My understanding is that sample() in 3.6.0 did, in fact, change in ways that detach it from set.seed().
You can use RNGkind() or RNGversion() to recapture the old behavior. See https://cran.rstudio.com/bin/windows/base/NEWS.R-3.6.1.html in the section CHANGES IN R 3.6.0 . Also, please do not post in HTML.
