Trouble loading large .rds matrix into Alteryx


I have a large data matrix that I created in R that is 5.6GB. I want to load it into Alteryx for further transformation and analysis. I am having trouble loading and writing it to Alteryx. Here is the script I have tried using in the R tool, and the outcome:





dat <-"~file.rds"))

write.Alteryx(dat, 1)


After 3.5 minutes, I get this error message: "The R.exe exit code (4294967295) indicated an error."


If I run this code to test if it can read the matrix:






I see it read the matrix and outputs some of the data. It just seems to be a problem when I try and assign the data somewhere.

Hi @creily


This could be related to the "fake" R error listed here -


Another possibility, however, is that the connection between R and Alteryx is timing out. When writing out to Alteryx, are you able to write a portion of the data? (you may try something small like 1 record, and if it works, increase the size). If this is the case, there is a defect in place for this type of behavior. (you may still want to follow the above thread to get rid of the error if this is occurring)


As a workaround, I would suggest trying to write it out to Alteryx in batches to multiple outputs (or multiple R Tools if need be)





I was using the most recent Alteryx, and what ended up fixing the problem was uninstalling and reinstalling the previous version.
