Power BI can't show basic text results via the R script visual ?
Can the R custom visual not show text results?
I just used the summary(dataset) function. And in R this properly shows the min/max/median/etc. but when I attempt the same script in R within Power BI I get the following error message:
"No image was created. The R code didn't result in a creation of any visuals. Make sure your R script results in a plot to the R default device."
I've correctly run R scripts via Power BI before, so I don't think my setup is incorrect. It seems odd though that Power BI can't display any/all output from an R script. This is frustrating, especially when it comes to troubleshooting.
Am I not looking at this correctly? Or is there something I'm missing?
Any thoughts/suggestions would help.
Thanks!

As you say R script visual only show image but a possible way to display the result of summary function is to use the grid.table function of the gridExtra package . I make an example with the iris dataset. See image below.
Surely this does not cover all your needs but I hope it will help you.

i believe all R output should be of image datatype rather than string.. hence "visual"
Right. But how often is something displayed that is not a visual? The Card "visual" is a good example of this where it's a single number that has to be shown.
I have linear regression model in R that is providing me with a single forecast that I would like to display in Power BI. But I can't seem to find a way to do it since Power BI can only display R visuals rather than the results of the R script itself.
