R UDF Library Error on Syntax
I am creating UDFs for a system and built a simple R script. However, after loading the script to the server and running CREATE LIBRARY correctly i get the following
sql:statement.sql:3: ROLLBACK 3399: Failure in UDx RPC call InvokeSetExecContext(): Error calling setupExecContext() in User Defined Object [] at [/scratch_a/release/vbuild/vertica/OSS/UDxFence/vertica-udx-R.cpp:129], error code: 0, message: Exception in Validate Library:<text>:2:33: unexpected input
1: myfunction <- function (dataset){
I encountered this issue before and realized there is something wrong with how Vertica reads the file. The my solution approach was to place the marker right before the "{" then ENTER, then BACKSPACE and SAVE.
I suspect this has to do with text format. But the latest error wasn't solved this way, the script had to be copied and saved entirely in a separate file.
Any ideas, suggestions, or insight?

Vertica displays the above error when there is an error in the R script. It looks like your file may have some invisible special characters. Please create a new file and then try creating the library. If the problem persists, please attach your file to the post.
Thanks

It had special characters but they are related to how Linux reads a file generated in Windows. The issue has been solved and we only update the file to avoid the error.
