rearranging data frame rows
Hi All,
I have two data frames. The first contains data about a number of individuals,
coded in the first column with a name, in an order I find convenient.
The second contains different data about the same indivduals, in a different
order. Both data frame have the individual names in the first column.
I need to reorder the second data frame so the rows are rearranged in the same
manner as

glmmPQL
Dear R users,
can anybody explain me why the function glmmPQL(.) behaves in different
ways, depending on the number of measurements/individuals you use? To
show you this, I generated two examples. The first one includes 20
indivduals with each 100 repeated measurements (binary response), the
second one includes 40 individuals. The 'individuals' differ only in
different x values. I

[OT] "_" inserted in postings
Sorry if this is too "OT", but there is a particular relevance to
postings to R-help.
Of recent times, I have received several postings via R-help (and some
other mailing-lists) in which the "_" character is inserted where,
presumably, a space, " ", was intended. An example (received this
morning) is below, which (from the headers) was originally sent

saving rounded numbers as a new variable in a dataframe
A basic question, but one that eludes me. I have created a new variable
$numurder, which I have rounded off. I want to save the rounded off version
of this variable to an existing datafile called 'ngri.csv' .

improving a bar graph
Hello,
Below is the code for a basic bar graph. I was seeking advice
regarding the following:
(a) For each time period there are values from 16 people. How I can
change the colour value so that each person has a different colour,
which recurs across each of the three graphs/tie epriods?
(b) I have seen much more sophisticated examples using lattice (e.g

ZFS + Raid-Z pool size incorrect?
I''m seeing odd behaviour when I create a ZFS raidz pool using three disks. The output of "zpool status" shows the pool size as the size of the three disks combined (as if it were a Raid 0 volume). This isn''t expected behaviour is it? When I create a mirrored volume in ZFS everything is as one would expect the pool is the size of a single drive.

Expanding a ZFS pool disk in Solaris 10 on VMWare (or other expandable storage technology)
Hello all,
This is not so much a question but rather a "how-to" for posterity.
Comments and possible fixes are welcome, though.
I''m toying (for work) with a Solaris 10 VM, and it has a dedicated
virtual HDD for data and zones. The template VM had a 20Gb disk,
but a particular application needs more. I hoped ZFS autoexpand
would do the trick transparently, but it turned out
