Export the plot to a pdf or png - R

Question

Hi, I want to export the plots into images and store them for presentation purpose. I used below code -

> png("annual sales.png")
> ggplot(economics, aes(date, unemploy)) + geom_ribbon(aes(ymin = unemploy,ymax = unemploy +900), fill = "blue")

But it is not showing any images. What to do?

Answer 1

You need to close the device to see the image or file because its running in R.

Write below code - 

dev.off() 

After device completes its work to store the output in an external file, you need to close the connection of the device.

Ex:

png(filename="your/file/location/name.png")
plot(variable,[options])
dev.off()

Close the file and reopen the file to see the output file.
