I cannot help with your Rstudio probelm as I do not use it but as far 
as your plotting question is concerned:

1 - do you really want to see all of the residuals? Why not just keep 
the ones outside the range -2 to +2 which you might then need to study further
2 - the pictures would probably be clearer if you identify and do not 
print out the two studies with r very close to -1 as they are 
compressing everything else
3 - hollow circles are often a good idea when you have overprinting.
