Hi all, This is probably a blindingly obvious question: Why does it matter in the uniroot function whether the f() values at the end points that you supply are of the same sign? For example: f <- function(x,y) {y-x^2+1} #this gives a warning uniroot(f,interval=c(-5,5),y=0) Error in uniroot(f, interval=c(-5, 5), y = 0) : f() values at end points not of opposite sign #this doesn't give a

Hi, Shouldn't the following commands produce a nice jpeg file, or am I missing something? hist(rnorm(1000)) dev.print(file="test.jpg",device=jpeg) I get a very tiny (6x6 pixel) jpeg every time.

I thought I would try btrfs on a new installation of f14. yes, I know its experimental but stable so it seemed to be a good time to try it. I am not sure if I have missed something out of all my searching but am I correct in thinking that currently: I. it is not possible to boot from a snapshot of the operating system and, in particular, the yum snapshots cannot be used for

(Moving from offlist discussion.) I''m interested in opinions... Assume there are four single vcpu domains A, B, C, D, running on a 2-CPU physical machine. We wish to test for time skew on domain A. Assuming B, C, and D are all running some workload that attempts to fully saturate the (single) cpu. 1) Should the affect on domain A be essentially the same regardless of what load
