The Release Package 1.2 page on the BioConductor web site indicates that this release "Requires R 1.7.1 or later."

I recommend that the text near the top of the BioConductor Release Package 1.2 page be modified to read: "Requires R 1.7.0" Thanks. > library(marrayInput) Loading required package: marrayClasses Loading required package: Biobase Welcome to Bioconductor Vignettes contain introductory material.

I recommend that the That shouldn't have anything to do with the fact that the package was built under 1.7.0, but rather most likely involves tightre checking in 1.7.1. Perhaps one of the marray* folks know something about this? -J
