[英]Error ggplotly: VECTOR_ELT() can only be applied to a 'list', not a 'NULL'
I'm using R 3.3.3
and RStudio 1.0.136
, and the latest versions of all the packages. 我正在使用R 3.3.3
和RStudio 1.0.136
,以及所有软件包的最新版本。
I get this error with the plotly
package 我用plotly
包得到了这个错误
> 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: 我“打印”ggplot后不再出现此错误:
> ggiris
> ggplotly(ggiris)
It occurs not only in RStudio, but also in a Shiny app. 它不仅出现在RStudio中,还出现在Shiny应用程序中。
Any hint ? 任何提示?
Note: This more likely occurs with a "fresh" session (just after opening RStudio). 注意:这更可能发生在“新鲜”会话中(刚打开RStudio之后)。

I am getting the same error when I change characteristics associated with a ggplotly object within a package I am building. 当我在我正在构建的包中更改与ggplotly对象关联的特征时,我收到相同的错误。 Short term fix is to quit and restart the session, as mentioned in a comment above. 短期修复是退出并重新启动会话,如上面的评论中所述。
I just encountered the same error on my computer, for the same context. 我刚刚在我的计算机上遇到了相同的错误,对于相同的上下文。 I simply update packages from RStudio interface, then I get the error. 我只是从RStudio接口更新包,然后我收到错误。 You probably need to update your R version, it worked for me. 你可能需要更新你的R版本,它对我有用。
Hope it will help you! 希望它能帮到你!
