Version 1.9 of the survey package, now percolating through CRAN, adds a beta implementation of replication weights. These can either be created from a survey design (using BRR, JK1, or JKn schemes) or provided by the user. These have been tested on only a few examples so far: there seem to be relatively few published datasets with suitable analyses. As with earlier versions of the package, I particularly welcome feedback on the user interface from practising survey statisticians. -thomas Thomas Lumley Assoc.
