Here is my 2 lines R code (recipes)
ctg <- read.dataset("testIn")
write.dataset(ctg,"testOut")
I have the following messages and error:
[1] "Start writing table to file ..."
[1] "Done writing table to file ..."
Error in write.dataset(ctg, "testOrder") :
Unable to write dataset TRAININGPA.testOrder : RuntimeException: Session doesn't exist
Do you know where is the problem ?
Thanks
Hi,
For recipes:
In a general way, to work with R recipes, you would need to configure R first, then a basic R recipe would be:
library(dataiku)
# Input dataset
data <- read.dataset("name_dataset_in")
# Output dataset
write.dataset_with_schema(data,"name_dataset_out")
For notebooks:
It works the same way than for recipes (I also recommend using dataset_with_schema()).
But, you need to create the output dataset first.
Also, you should write in a managed dataset, it would prevent from some problems.
To create a manage dataset, click on the "all dataset types..." when you create a new dataset, then you will get this screen:
