The following Rmarkdown renders the plotly 3D graph in HTML, but not in PDF.

Testing plotly

```{r}
library(plotly)
p <- plot_ly(data=iris, x=~Sepal.Lengt         


        

Answer 1

Same issue with R markdown compile error:. You need to choose what format you want to KNIT to, tried to look at mine.
