Memory Limit Error from R recipe

I'm trying to run association rules on a fairly large file using arules in an R code recipe in Dataiku. After about 10 minutes, the job failed and I have received the error: "Error in R process: simpleError : R character strings are limited to 2^31-1 bytes"

Apparently this is related to a limitation using a 32-bit OS with R according to R documentation. Not sure why I'm experiencing this in Dataiku?
