Is bpaggregate from the BiocParallel package intended to be a drop-in replacement for aggregate? I am getting a somewhat cryptic error message when trying to use it:

library(BiocParallel)
aggregate(Sepal.Length~Species, data=iris, FUN=sum) # Works
bpaggregate(Sepal.Length~Species, data=iris, FUN=sum) # Return error

# Error in eval(extras, data, env) : object 'BPREDO' not found 

Thanks for the report; this should be fixed in BiocParallel version 1.14.2 (release) / 1.15.7 (devel) via biocLite() in at about noon Eastern time Monday, or via BiocInstaller::biocLite("Bioconductor/BiocParallel", ref="RELEASE_3_7") / ref = "master" now.
