Hi Paul Is there a concrete working example somewhere that shows how to use these to do an animation on Windows (R Gui &/or RStudio) using base R plot() and friends? I have several old examples somewhere that used to work (R < ~ 3), but now no longer work as before.

Hello: I want to present a sequence of plots as an animation. As a toy example consider the code function(n){for (i in 1:n){ plot(1:100,sin(i*(1:100)),type="l") title(paste("n=",i)) segments(0,0,100,0,col=2) }} This sort-of works on a MacOS platform, but the rendering of the plots is a bit choppy. Inserting a sleep function allows the plots to evolve smoothly.

I have a weird problem running R.app 3.3.2 under Mac OS X 10.10.5. I was trying to interrupt a command line using various Control codes until I discovered that ?Esc? is the escape key. (Makes sense!) Now I find that while I can enter new commands to R, they no longer echo back, so I cannot see what I am typing. On unix terminals CTL-Q will reset this, but it does not seem to work on the R

...l occupied. So we add the patch to free domU''s port when xenpaging exits. We need double free interdomain eventchannel. First free domainU port, and leave domain 0 port unbond, Then free domain 0 port.

The following two patches are about how to speed up in xenpaging when page in pages. On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds, but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash. What鈥檚 more,the dom0 is always in high I/O pressure.
