@RijinM maybe you could give us an example what kind of graphic is being produced. Maybe a small workflow without any secret data.

You could use the png() command from within the R node but that might als involve plotting.

library(Cairo)

png(my_path,width=1024,height=768, bg = "transparent", type="cairo")
plot.new

# your plot here

dev.off()

You also can handle images that are on your drive if they are SVG or PNG and bring them back into KNIME and work further with them:
