So use R interactively, rather than in batch mode typing at stdin. (Using --file puts you into batch mode.) Only in interactive use does the event loop give time to windows such as the screen device, pagers, data frame viewers .... I have no idea where you got the idea of 'R --slave --save --file=-' from: the way to use R 'at the command line' on Windows is to use Rterm. 'Rterm --slave --save' would do the same without the freezing, but most people do find prompts useful. -- Brian D.
