Suggestion: don't print ggplot object in DataExplorer:::plotDataExplorer.single()

[RoelVerbelen]

Thanks for your package! I'm using your plot_correlation() function in an R Markdown and am converting it to a plotly graphic via ggplotly():

library(DataExplorer)
library(plotly)
plot_correlation(iris) %>% ggplotly()

However, this command leads to first plotting it as a ggplot object and then as a plotly object.

This could be solved/prevented by deleting the print(plot_obj) line in DataExplorer:::plotDataExplorer.single(). The ggplot object is returned invisibly in the last line anyway. Would that be something you would consider doing or would it break your functionality elsewhere?

Yes, plots don't show up during non-interactive mode (See this SO answer). There is no silver bullet here, so I chose to have it printed by default.

For your R Markdown use case, I suggest separating the code block into an include=FALSE section:

```{r create, include=FALSE}
library(DataExplorer)
library(plotly)
out <- plot_correlation(iris)

Then call the output from another block:

````R
```{r plot}
ggplotly(out)

Thanks for your response. I understand the trade-off. In R markdown, the workaround is easy enough.
