calling worflow credentials from R Snippet

Hello,

Is there a way to call workflow credentials from R snippet?

I have a R code in R snippet to call teradata .fastload and BTEQ command, which is used for loading millions of rows into teradata database*. Currently, the database credential is hard coded. Is there a way to call the workflow credentials within R?

Thanks,

Palupi

*database writer is too slow for the operation. therefore, i opt for fastload and bteq instead.
