Kevin is totally correct. But I think you might be misunderstanding how easy conversion is. Take this R Markdown Example:
If we have this chunk with Python code:
```{python}
import pandas as pd
DF = pd.DataFrame({'x' : [1., 2., 3., 4.],
'y' : [4., 3., 2., 1.]})
```
We can view (with an implicit convert) by simply doing this:
```{r}
View(py$DF)
```
Which pops up in the IDE very nicely:
