Undefined variables when using R visual

[Irissie-2]

I am trying to build a visual with R, but I cannot use the variables I have in my datasets.

When I select the R visual and want to select which variables I want to use, they are undefined (I selected two, see below).

# The following code to create a dataframe and remove duplicated rows is always executed and acts as a preamble for your script: 

# dataset <- data.frame(undefined, undefined.1)
# dataset <- unique(dataset)

# Paste or type your script code here:

Does anyone know why this happens?

I have built dashboards using PowerBI visuals with this dataset and these variables before, I just want to add a new visual to a page.

I am facing the same issue and unable to find any solution.😐

Table columns

Are these table columns called "undefined" and "undefined.1" ? Are they maybe the result of a column split operation in Power Query?

[Irissie-2]

No, they actually all have meaningful names, that also work in the visuals. It happens to all columns, in all tables. Maybe it has to do with a setting somewhere? But I don't know where to look..

There's only a single prompt to enable scripting when you set this up the first time.

Can't reproduce your issue.  Can you try with a fresh PBIX and some sample data?

[Irissie-2]

Good point. I tried with example data and then everything was normal..

But on all of our own data (separate source data, separate PowerBI files) it doesn't work and shows undefined.1 etc.. 

[lbendlin]

when you say "variables"  do you mean table columns or measures?
