R Passing NA's in data frame to Kognitio - External Script
Was stumped on this issue for longer than I care to admit but it is fairy simple to solve passing NA values within R data frames to Kognitio as NULL values when using external scripts.
Given df
A | B
--|------------
--| 1 | NA
and you want to "write it back" to kognitio, where column B is declared as an INT, through stdout you would simply use the following
write.table(x, row.names = FALSE, col.names = FALSE, sep = ",", na = "")
The import parameter being na = "".
Again its a simple solution - and I am sure there are more (efficient for larger df's?)
One issue I havent found a solution for - passing back multiple data frames. Unsure if this is even possible.
