Resizing plots saved as png from ggplot in RStudio

[Wacek Kusnierczyk]

Hello,

I am using RStudio (excellent!) to produce HTML reports, including plots generated with ggplot (excellent!).  I need to reuse the png figure files in a separate slide presentation.  By default, the plots are square. 

The plots shown in the RStudio plot tab are automatically resized.  How do I modify the shape and size of plots exported by ggplot?

Best,
Wacek

Hi Wacek

In RStudio, directly in the 'Plots' Tab, you've got the dropdown menu 'Export' with 'Save plot as Image'
In the subsequently opening separate window you can, among other things, directly set width & height.

cheers
