finer control of scales in xyplot
When plotting over multiple pages in lattice, I'd like to be able to
have "same" scales within a page, but "free" scales between pages. In
other words, something like:
z<-data.frame(x=1:100,
y=runif(100),
d=rep(1:2,50),
p=rep(1:2,each=50))
plot<-xyplot(y~x|d*p,
data=z,

R uses private function in libc (PR#9107)
Full_Name: Quanah Gibson-Mount
Version: 2.3.0, 2.3.1
OS: Linux
Submission from: (NULL) (171.66.155.86)
libc used to export the symbol:
__libc_stack_end;
however, newer versions of libc no longer export it. R has some serious
problems around this, because the code has:
# ifdef linux
extern void * __libc_stack_end;
# endif
and
#if defined(linux)
R_CStackStart = (uintptr_t)
