Data Function R returns "agrument is of length zero" for conditional equations

[Michael Ng]

Tried making a data function based on this info:https://community.spotfire.com/questions/self-referential-calculated-column...

I am not too sure why it returns this error below:

TIBCO Enterprise Runtime for R returned an error (10)

The data function 'SubAssyScript' could not be executed.

Error in eval(expr, envir, enclos) : argument is of length zero

eval(expr, envir, enclos)

eval(expr, envir, enclos)

 

Script:

# Define Variables

This could be an indexing issue. Your sequence starts at 1 and you try to compare X[1] with S[0]. But S[0] doesn't exist. R starts counting at 1, not like Python that starts with 0. Please make sure to catch the issues with your first/last index when you compare across different data rows.
