Power Query lists don't seem to survive when going through R scrip back to Power Query.
This simple R-script below returns a none list column, eventhough the column was a list in the earlier Power Query step
---
# 'dataset' holds the input data for this script
save(file="dataset", dataset)
output <- dataset
---
Is this by design, a bug, or something that I do wrong?
The reason for mecreating the simple example above was that I didn't manage to create a list in R and send it back to Power Query. E.G.
output <- dataset
output$NewListColumn <- list(1:3))
and then back in Power Query expand that column
Before R:
OriginalColumn
==========
A
B
C
After R (and Power Query), it might look something like this:
OriginalColumn, NewListColumn
==========, ==========
A, 1
A, 2
A, 3
B, 1
B, 2
B, 3
C, 1
C, 2
C, 3
Hi pade,
I just tried the
save(file="dataset", dataset)
output <- dataset
And it returns the column entered in Query Editor;
For
output <- dataset
output$NewListColumn <- list(1:3))
I think there should be one “ ) “ in <- list(1:3))
In addition, what would you like to achieve, to use R List function here? Maybe we could achieve that through other ways.
Regards
