i´m looking for an solution and hope that somebody can help me.
With KNIME i´m retriving data from our system. The code knows which R-libraries are needed. In this syntax line stands the windows user as not changegable text.
Now what i want to have is, that before running the R-Source KNIME picks up the actual windows user and replace it as needed.
I got the actual User information by using the ‘Extract Context properties’. But now i´m stocking in the replacement step.
The first lines of the R Source Code are looking like this:
library(RODBC, data.table, lib.loc=“C:/Users/lozano/R/win-library/3.3”)
If somebody else from my team use this workflow i don´t want, that they first have to adjust the parameters for a correct data download. By using the ‘Extract Context properties’-Node it should happen automaticly.
Any suggestions how to solve this?
