On further consideration of the first machine translation, I am  
guessing that you really wanted the facilities offered by:

?split.screen
?screen   #same help page

That would let you choose which "screen" you wanted selected for  
plotting. Run the examples on the help page. Those facilities should  
not be mixed with layout().
