I'm using R 3.3.3 and RStudio 1.0.136, and the latest versions of all the packages.

I get this error with the plotly package

> ggiris <- qplot(Petal.Width, Sepal.Length, data = iris, color = Species)
> ggplotly(ggiris)
Error in grid.Call(L_convert, x, as.integer(whatfrom), as.integer(whatto),  : 
  VECTOR_ELT() can only be applied to a 'list', not a 'NULL'

This error does not occur anymore after I "print" the ggplot:

> ggiris
> ggplotly(ggiris)

It occurs not only in RStudio, but also in a Shiny app.

Any hint ?

Note: This more likely occurs with a "fresh" session (just after opening RStudio).

  • Thank you for testing @apom. Me too, I've never encountered this issue on 3.3.2. – Stéphane Laurent Mar 19 '17 at 15:57
  • Cannot reproduce it either, R 3.3.2 and R 3.3.3 using RStudio 1.0.136 on Windows 10 – Maximilian Peters Mar 20 '17 at 11:57

    This occurs for me too. `RStudio 1.0.136, R 3.3.3, Windows 7 x64, ggplot2_2.2.1` Seems quite random. I restart my session to get rid of it. I am only using ggplot2. So, this probably not a ggplotly issue. – mindlessgreen May 12 '17 at 15:22

    Thanks @rmf, I'm feeling less alone now. As you say, quite random. – Stéphane Laurent May 12 '17 at 17:40
  • I got the same error in R version 3.2.3 (Ubuntu command-line). I am using pheatmap. Started a new session and no error. – Abhishek Aug 23 '17 at 08:35
  • This https://github.com/rstudio/rstudio/issues/2919 suggests that the problem may come from having a NULL Viewport, but I don't know how to fix that. – Mark D Oct 29 '20 at 13:06

I am getting the same error when I change characteristics associated with a ggplotly object within a package I am building. Short term fix is to quit and restart the session, as mentioned in a comment above.

I just encountered the same error on my computer, for the same context. I simply update packages from RStudio interface, then I get the error. You probably need to update your R version, it worked for me.

Hope it will help you!

    This error "randomly" occurs for me. I have all the latest versions, of the packages and R. – Stéphane Laurent Mar 22 '17 at 11:49
  • Have you found a solution @StéphaneLaurent? I have the same error on a script that runs every weekday and the error occurs about once a month. On scheduled scripts its not possible for me to restart R/Rstudio or other quick fixes. Would be very thankful for any hints,... – Tonio Liebrand Jul 26 '19 at 11:34
