Greetings and Salutations All,
Recently, I've had the need to collide large matrices 1x10^7 using code written in RcppArmadillo.
Initially, I triggered:
Error: Mat::init(): requested size is too large; suggest to enable ARMA_64BIT_WORD
Upon a quick search, I stumbled upon a Stack Exchange post by Dirk:
"Update on 2013-04-30: This was actually an Armadillo bug, which was just fixed upstream. A new RcppArmadillo verion 0.3.810.2 is now in SVN, and should migrate soon to CRAN shortly. You no longer need to define ARMA_64BIT_WORD."
The above definition not listed.
Two quick questions:
1. Was the default support for ARMA_64BIT_WORD removed? (RcppArmadillo >= 0.4.5.550.1.0) If not, is there a trigger I need to add to my source to ensure ARMA_64BIT_WORD is active?
2. If I make the code I'm currently working on available as a package on CRAN, would I have to direct users to modify the RcppArmadilloConfig.h?
