错误ggplotly:VECTOR_ELT()只能应用于'列表',而不是'NULL' [英] Error ggplotly: VECTOR_ELT() can only be applied to a 'list', not a 'NULL'
问题描述
我正在使用 R 3.3.3
和RStudio 1.0.136
,并且所有的最新版本。
包装中出现此错误
> ggiris <-qplot(Petal.Width,Sepal.Length,data = iris,color = Species)
> ggplotly(ggiris)
grid.Call中的错误(L_convert,x,as.integer(whatfrom),as.integer(whatto),:
VECTOR_ELT()只能应用于'list',不是'NULL'
在我打印ggplot后,这个错误不再发生:
> ggiris
> ggplotly(ggiris)
它不仅发生在RStudio中,还发生在Shiny应用程序中。
任何提示?
$ b
注意:这很可能发生在新鲜会话中(仅在打开RStudio之后)。

当我更改包中的ggplotly对象的相关特性时, 。短期修复是退出并重新启动会话,如上面的评论中所述。
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).

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.
