Developer product requirements and r-code portability

R-code is portable between any two environments if the following are true:

The user interface is the same—MS-Windows or character mode.
Note: If a procedure contains no code that writes to the screen, its r-code is portable across user interfaces. This is typical, for example, of database schema trigger procedures.
The database type (the DataServer or combination of DataServers connected during compilation) is the same.
The r-code version is the same.
The platforms are compatible (32-bit versus 64-bit).

For more details about these requirements and how they affect r-code portability, see Appendix B "R-code Features and Functions."
