display a png picture and hold it for 3 seconds in R

Question

I am very new to user interface using R. I have a png file. I would like to display it at the beginning of my script, keep it to stay for around 3 seconds and close it automatically.

I tried file.show(). R will pop the png file. But that is not what I want.

I prefer to make it appear in front of my IDE like a splash screen that appears before a program starts. I mean it will be similar to a welcome pic before the user really start to run the script. After 3 seconds, it will disappear and R will start to run the script automatically.

I wonder any R package can make my idea come true? Thank you.

This probably could get you started. The image will appear in the default RStudio bottom-right panel for 3 seconds and then will disappear. Warning: dev.off() will erase all your plots that you had in workspace before running the script.

#At the very beginning of the script, execute:
library(png)
img <- readPNG("path/baboon.png")
windows()
grid::grid.raster(img)
Sys.sleep(3)
dev.off()

#... your script continues here
print("Did you see that baboon??")

Edit: windows() does exactly what you need, I think
