Error in rxImport: Expected 8

Question

I am trying to read a file with 35.000.000 rows and 105 columns in R and decided to use Revolution R Enterprise 7.4, with this code:

 input <- RxTextData(data, isFixedFormat = F,delimiter = "\t")

 s <- rxImport(inData = input,outFile = output,overwrite = T)

but the code throws the following error:

Error in doTryCatch(return(expr), name, parentenv, handler) : Write error: expected 8 got

Does anybody know how can I solve this error?

Thanks

I'm an engineer on Microsoft R Server, and this error is an identified bug that is currently being addressed, This error occurs for data frames over 4GB in size.

It will be fixed in the next release of MRO/MRS.
