question about anova() output
Hello,
I am getting output from anova() and summary(aov()) that depends on the
order of the factors in the fitted model object, and this has me baffled. I
see this dependency with the data.frame below but not with an example (table
6.4) from Montgomery's DOE book. This is with R 1.3.0 on Debian GNU-Linux.
Where have I gone wrong?

finding row and column indices of date in multiple columns of a data frame
Hi,
I have a data.frame SAMPLES with columns:
Site Site# Season Day1 Day2 Day3
Day1, Day2, Day3 are class "Date", the other columns are numeric or
factor.
I have a date "mydate" that may or may not be listed in my data.frame
and I need to find that out.
If "mydate" is there, I want to get the number of the data.frame row
where it occurs.

Let's say I have a dataset with columns like this

Counting entries to create a new table
Hi,
I am an R novice and I am trying to do something that it seems should be fairly simple, but I can't quite figure it out and I must not be using the right words when I search for answers.
I have a dataset with a number of individuals and observations for each day (7 possible codes plus missing data)
So it looks something like this
Individual A, B, C, D
Day1 1,1,1,1
Day 2 1,3,4,2

I would like to visualize the hospitalization within one year of several
patients using a bar chart. For each patient the stay in a hospital
should be illustrated with a dark colour a if there is a stay at home
between 2 hopital stays, it should be illustrated with a bright colour.

Name assignment in for loop
Dear helpeRs-
I'm using a for loop to create a series of models.
I'm trying to assign a name to each model created,
using the loop index. The loop gets stuck at the name
of the model, giving the error "target of assignment
expands to non-language object". The linear model runs
without error; only the name is problematic.
Here is the current loop syntax. The use of dat

any valid up-to-date info about Kamailio-Asterisk integration ?
Hi all
Have recently watched Matt Jordan's session on Kamailio World 2014
On slides 26-29 of his presentation
(http://www.kamailio.org/events/2014-KamailioWorld/day1/09-Matt.Jordan-Asterisk12-And-PJSIP.pdf)
he speaks about a (completely new, for me at least) approach to build
scalable telephony systems, using N instances of Kamailio and N

something like this:

[PATCH libnbd] lib: Use symbol versions.
This patch adds support for symbol versions. It is based on what
libvirt does.
The generated syms file looks like:
LIBNBD_1.0 {
global:
nbd_...;
nbd_...;
local: *;
};
In a future stable 1.2 release, new symbols would go into a new
section which would look like this:
LIBNBD_1.2 {
global:
nbd_new_symbol;
nbd_another_new_symbol;
local: *;
} LIBNBD_1.0;

Operaciones con Arrays...creo.
Muchas gracias, Javier, por tu respuesta.
Me sobrevalorás. Mi última clase de matemática como tal fue en 4º de
secundaria, y era la matemática que nos daban a los de letras. Ni te cuento
hace cuántos años. No puedo seguir la mayoría de lo que comentás sin hacer
