I’m very happy to report that after 6 months of development by a team of 8 developers (at its peak) and two months of beta testing, we’re ready to release REvolution R Enterprise for the 64-bit Windows platform.

On behalf of all of us here at REvolution, I also want to acknowledge and thank the R Core team who created R in the first place (and therefore most of the code in REvolution R). In particular I’d like to thank Brian Ripley and those others who took the lead in porting R to 64-bit systems at a time when 64-bit applications were still rare, giving the R community early access to large-scale data analysis. (Thanks also to Brian Ripley for his detailed comments during the beta test.) I also want to give thanks to all the package developers who have enriched the R ecosystem, and especially those that have helped us during the package porting project.
Based on our experience with R users and the downloads from our CRAN mirror, Windows is the largest installed platform for R, and a 64-bit version of REvolution R Enterprise will help R users process much larger data sets than before. With some tweaking, 32-bit Windows machines can access up to 3Gb of RAM, which in practice limits R on 32-bit Windows to datasets smaller than a gigabyte. On the 64-bit Windows platform those limitations disappear: REvolution R Enterprise there can manage much larger datasets using a greatly expanded virtual-memory address space, and the fact that you can install and use much more than 4Gb of RAM can make those analyses run even faster. (Look for some specific examples in a subsequent post.)
