Execute R: Date Missing in Output
In my process I have have two operators. the first is read.excel and the other is Execute R. In the latter a script fills NAs in time series (daily). All good with that and when I test the script in Rstudio everything seems to be in place. Though all dates in the output of the operator are missing "?".
Well... in past similar situations that I came across already, after reading some posts here, I was able to proceed by transforming date to character and then in R I would use nominal to date. Which is the solution given in this old thread: https://community.rapidminer.com/discussion/41481/why-date-data-is-missing-after-output-from-execute-r.
If the script works in Rstudio I guess that the issue is just "coming back" to Rapidminer, but what I don't get is why transforming date to character in R is not a solution.
Your help is much appreciated because this is nerve-racking
