Standard UDXs
The standard R Language Adapter installation includes a number of UDXs that can be used
in any user code. The client-side nzLibrary for R package assumes them to be
registered in the nzLibrary for R database.
These are:
- r_udtf
- A standard entry point for R AEs. Set to sparse output type and returning a two-column table:
TABLE(columnid INT4, value VARCHAR(16000)). - r_udtf_any
- A similar UDTF but returning
TABLE(ANY),which requires a shaper function for this UDTF to run correctly. - r_uda
- An aggregate. Currently designed to be used from the
nzLibraryfor R client package. - placefile, createfile, and appendfile
- UDXs used by the
nzLibraryfor R client package to set up data files with user-defined function in the workspace directory.
