My question is similar to this one. I am using the default notebook of RStudio (the one you get when you click "New file -> R notebook". When I run the code chunk
```{r}
plot(cars)
```
RStudio displays the result in the editor. However, when I click on "preview" the output does not show the result. The result is visible if I use the command "Knit to Html", but with less functionality so this is not what I want.
Rstudio Notebook did work fine for a few hours and then not anymore, I cannot find why.
I'm using the preview release of RStudio v1.1.430 (but had the same problem with the current non-preview version) and I am running R 3.4.3.
Could anyone help me?
