r - Control size of figure in Rstudio presentation



I'm creating a presentation in RStudio (.Rpres). I have a figure that is too large and extends beyond the screen. How can I reduce it?

Too big, need to reduce size

Figure 1
![alt text](fig1)

This should work:

<div align="center">
<img src="fig1.jpg" width=800 height=600>

Simply adjust the width and height as required.


You can use

```{r, echo=FALSE}
knitr::include_graphics(path,  dpi = NULL)

in a chunk and then set image height and width options in the chunk options. This should work with all output formats.
