[Bioc-devel] bpparam Non-deterministic Default

[Martin Morgan]

I'm not sure that this is a good idea? For instance R does not set the random number stream to be the same by default. Not sure what others might think... Martin

    Good day,

    I maintain an R package which makes use of functions such as bplapply which has bpparam() as the default. I have received feedback from a beginnre user that the results change when he knitted his R Markdown document a second time. This stems from the default constructor of bpparam() which sets no RNGseed. I am wondering about the desirability of changing the RNGseed default in BiocParallel to a particular uncontroversial number, such as 12345, so that beginners get deterministic behaviour.
