[PATCH 1/2] Ocfs2: Add a new code 'OCFS2_INFO_FREEINODE' for o2info ioctl.
The new code is dedicated to calculate free inodes number of all inode_allocs,
then return the info to userpace in terms of an array.
Specially, flag 'OCFS2_INFO_FL_NON_COHERENT', manipulated by '--cluster-coherent'
from userspace, is now going to be involved. setting the flag on means no cluster
coherency considered, usually, userspace tools choose none-coherency strategy by

lme() F-values disagree with aov()
I have used lme() on data from a between-within subjects experiment. The correct
ANOVA table is known because this is a textbook example (Experimental Design by
Roger Kirk Chapter 12: Split-Plot Factorial Design). The lme() F-values differ from
the known results. Please help me understand why.

nls, convergence and starting values
"in non linear modelling finding appropriate starting values is
something like an art"... (maybe from somewhere in Crawley , 2007) Here

that one (dumped below). Whatever our trials and algorithms, even

Hello,
I saw this posting by Christopher Robert Woods. I am having the identical
problem with Samba on Suse Linux 7.2 (OS/390). Is there any known

Javascript & Rails future
Hi,
David H.H. announced recently that jquery is going to be the default in Rails 3.1, and that Prototype helpers / RJS are going into a gem.
What does that mean for the future? Should we progressively forget about things like javascript helpers, RJS, and all these fun parts of rails? And start coding with jquery/json in mind?
I''m not against that at all, but I have to admit I find RJS

non-parametric permutation and signed paired-difference distributions
Hi all
Consider the classic data below from Darwin on the heights of 15 pairs

it makes a difference.

persp question
someone sent in a question earlier about doing

Unfortunately, persp gives me an error that I don't understand because it says "object y not found". I'm sending y in as a parameter to persp similar to what ?persp shows in one of oits examples

stastistical test on normalized data
Dear R-maillit,
I have to perform a stastistical test to asses if two grug show the same or different effect on my prepartion.
I tested on the same preparation only one drug and I have to use normalized data due to high variability in the control condictions.
What type can I use?
A non paramatric test right?
And how can do it on R software?
Thanks in advance

histograms resulting from call to soil.texture
Hello,
Using the dataset below I produce a soil.texture plot (R code for this
included at the end). One will notice I have plotted the points based on
whether or not they are in a region called 'upstream' or 'downstream'. I'm
curious if there is a way to somehow extract counts of the number of points
(red points and blue points) falling within each classification (e.g. silty

The plot is ordered in this way HC RM190 RM198 RM202.
I would like it to plot in this way HC RM202 RM198 RM190.

Any suggestions would be much helpful.

improving/speeding up a very large, slow simulation
Dear R help;
I'll preface this by saying that the example I've provided below is pretty
long, turgid, and otherwise a deep dive into a series of functions I wrote
for a simulation study. It is, however, reproducible and self-contained.
I'm trying to do my first simulation study that's quite big, and so I'll
say that the output of this simulation as I'd like it to be is
