# Move Data Between Spotfire Enterprise Runtime for R and Open-Source R

You can transfer data objects between TERR and open-source R.

Both the TERR engine and the open-source R engine can read in plain ASCII data files (for example, CSV files) using the `scan()` and `read.table()` functions. To transfer basic data objects (vectors, matrices, factors, and data frames, for example) between TERR and open-source R, you must use other functions.
