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...

    Hi Anonymous

     

    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.

dannn777,

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.

    That's a good idea. I share your pain when I sometimes want to show a text value directly from R. I think you can get around this right now if you bake your R script into a custom visual. I haven't done it before but people make it sound pretty doable

      Anonymous,
      Thanks for the head's up. I'll keep looking around, but I haven't seen any examples. I've tried using simple summary(dataframe) or str(dataframe) functions and came up with errors in Power BI, but perhaps I'm misunderstanding you.

        I don't think the plain R visual will display anything other than a plot as of now. In order to get a visual to display text from R such as summary(dataframe), I think you would have to create your own visual. Check this out real quick and you may have some luck
