Change the size of R plot window

I need to make a larger R plot in KNIME and current settings is giving too small window for plot. Any idea on how to change the size of R plot window?


I tried to use the R function:

windows(width=10,height=10) in the R node and the window is enlarged but only shown for a few seconds, and then it disappears.

It seems that KNIME is closing the window by default.



The R View nodes have a png settings tab in their configuration dialogs, have you had a look at this?  Also, in case followup is needed, which R extension are you using?  Official, Labs, or Community? 



Thanks for the tips! I change now change the window size in the PNG setting.
