Empty Table when running R script on Power Bi

[Anonymous]

When running a simple R script adding two columns, the output I get is always "The table is empty"

My table is pretty simple, only 3 columns: 

and the script I am using is also very simple: 

I tried multiple scripts, and all of them are giving me an empty table. What is the source of the problem? Any help would be appreciated.

Hi @Anonymous 

add an output dataframe

# 'dataset' holds the input data for this script

dataset$Total <- sum(dataset$Age, dataset$Height)

output <- dataset
