osx - R x11 on Mac not functioning - or, functioning weirdly -

i have simple r script in file test.r:

x11() plot(1,1) 

from terminal, type "rscript test.r" , x11 opens , flashes plot point @ (1,1), , closes window, x11 remains open.

how keep plot open? why leave quickly?

r close device when process r dies (as when script completes). better way is:

pdf("file.pdf") plot(1,1) dev.off() 

then when run through rscript save file there. otherwise, you'll have have r stay alive isn't how should run in script.
