Debugging Power Bi R Custom Visual Using R studio

Are you developing a R custom visual for Power Bi and got fed up in the debugging process, here is the one easy way to debug your R visual in R Studio.

Add the following code to the top of you sript.r file

You can also find the below code in this gist https://gist.github.com/praveenn-vbi/1c92ca338845f9a2367a33b83b698458

#DEBUG in RStudio

fileRda=”C:/temp/Data.Rda”

if(file.exists(dirname(fileRda))){

if(Sys.getenv(“RSTUDIO”)!=””)

load(file= fileRda)

else

save(list = ls(all.names = TRUE), file=fileRda)

}

Now package your R visual and import the packaged R visual into you Power Bi Destop App. Assign the data to your R visual.

Now you can find Data.Rda file in C:/temp as we metioned in the above.

Now open the Data.Rda file in RStudio. The data you set to your custom visual will get imported to R your session variables.

That’s it, now you can directly open your script.R file in your R Studio and debugg it.
