ordering of factor levels in regression changes result
I was surprised to find that just changing the base level of a factor variable changed the number of significant coefficients in the solution.
I was surprised at this and want to know how I should choose the order of the factors, if the order affects the result.
Here is the small example. It is taken from 'The R Book', Crawley p. 365.

Hi Kelly,
Try running 'iostat -xdmc 1'. Look for a single drive that has
substantially greater await than ~10msec. If all the drives
except one are taking 6-8msec, but one is very

Slow performance of gluster volume
OK my understanding is that with preallocated disks the performance with
and without shard will be the same.
In any case, please attach the volume profile[1], so we can see what else
is slowing things down.

I have collected and classified some information of:

Samba performance issues
Hi all
We are implementing samba-ldap to act as an nt pdc and are seeing
performance problems.
We have a 1ghz, 3gb Ram, 36gb box that is running samba-2.2.5 and

Clients are all Win2k SP3.
All the ldap requests are to the localhost interface.
The box is acting as the PDC for the domain, and also sharing diskspace

question about converting a matrix to a dataframe
First I have a matrix called stocks1:

Here are the first 5 rows of the last 4 columns:

[,1] [,2] [,3] [,4]

[5,] 82.74 35.18 30.24 27.41
Now, why can't I convert this into a dataframe?

How to read percentage and currency data?
I'm struggling to find any help on this seemingly simple question - how does
one read data with percentage (%) or currency (?,$ etc.) signs? When I try
to read a data file which has any of those symbols in the data fields, they
are read as characters rather than values. Is there a function or library
which can deal with such values?
As an example, I use this sample from one of chinna's

Slow performance of gluster volume
Hi Krutika,
I already have a preallocated disk on VM.
Now I am checking performance with dd on the hypervisors which have the
gluster volume configured.
I tried also several values of shard-block-size and I keep getting the same
low values on write performance.
Enabling client-io-threads also did not have any affect.
The version of gluster I am using is glusterfs 3.8.12 built on May 11 2017

conditions simpler way

I have a MCMC result in x1. I was wondering if there is a simpler, more
elegant way of evaluating the estimate of an integral then this (I am
pretty sure there is):
Also if I want to count the x's say -1<x<2 but not the ones in the burn
in period.

z <- -2
burnin <- 2000
