Plotting dates and grid lines on the X-Axis of xyplot
I have a plotting function that is plots a multi-panel plot, with the x-axis
as a date and various y-axes.
I would like to control the frequency of the X-axis labels, ticks and grid
lines. However with the following code I get no annotation on the X-axis at
all.

data manipulation in R
Dear List:
I have a data manipulation problem that I was unable
to solve in R. I did it in SQL, and it may be that
the solution in R is to do it in SQL, but I wondered
if people could imagine a vector-based solution.
Imagine a list A[i] of observers who observe some set
of events B[j]. Each observer i may observe one or
more events, and each event j may have been observed
by one or more

SQL like function?
Hi RUsers,
I am wonder if I can search observations whose IDs matches any of the
values in another vector, such as in MySQL. While I am learing MySQL for
future database management, I appreciate if anyone could give me a hint.
Suppose I have one 5*1 vector containing observation IDs and
frequencies, and one 3*1 vector containing observation IDs.
observation<-c(1,2,3,4,5)
ID<-c(1,3,4)

Alternating between "for loops"
Dear All,
I would like to apply two different "for loops" to each set of four columns
of a matrix (the loops here are simplifications of the actual loops I will
be running which involve multiple if/else statements).
I don't know how to "alternate" between the loops depending on which column
is "running through the loop" at the time.

Declaring ActiveRecord observers
Hello
I''m using the ''act_as_authenticated'' plugin to implement a small and
simple authentication system in my app. Everything is working just
fine and the world is a better place to live in. The plugin creates a
ActiveRecord observer in order to send the newly registered user a
confirmation e-mail.
Per the API docs [1], one should declare the observer in the

questions about "metafor" package
Hello,
I would like to do a meta-analysis with the package « metafor ». Ideally I would like to use a mixed model because I’m interested to see the effect of some moderators. But the data set I managed to collect from literature presents two limits.
- Firstly, for each observation, I have means for a treatment and for a control, but I don’t always have corresponding standard

Tests for Two Independent Samples
Dear R users,
I have got two samples:
sample A with observation of 223:
sample A has five categories: 1,2,3,4,5 (I use the numer 1,2,3,4,5 to
define the five differen categories)
there are 5 observations in category 1; 81 observations in category 2;110

Removing form observers
Hi,
I''m developing a Rails app which uses dynamic forms. To implement
these, I''ve used AJAX and Rails''s built-in form observers.
Unfortunately, I''m having a problem.
This is how the form starts:
* Country select box [OBSERVED] (Republic of Ireland selected)
* County select box [OBSERVED] (none selected, list of Republic of
Irish counties in the drop down)

Function similar to cumsum/cumprod
Hello, everyone
I wonder if there is in R somewhere a function similar to cumsum().
The function calculates a statistic (say mean or standard deviation)
buy adding consequtively one more data point.
So, say I have a timeseries of 100 observations.
I start by calculating mean of first 30 observations
Then I add one observation and calculate mean of 31 observations
Then I add one more observation

mgcp transfer takeback with ata186 (logs with comments - long post)
Hi,
in following of a recent discussion I got to work on MGCP with the Cisco
ATA186 again, and got it to work very nicely. However, there is a little
thing with transfers I would like to get comments on:
Call comes in from PSTN and goes to an ATA186 (MGCP)
Call is answered and then, using flash, transferred to another extension
If the extension is available, there can be an announcement and

Anova Type II and Contrasts
the study design of the data I have to analyse is simple. There is 1 control group (CTRL) and 2 different treatment groups (TREAT_1 and TREAT_2).
The data also includes 2 covariates COV1 and COV2. I have been asked to check if there is a linear or quadratic treatment effect in the data.
I created a dummy data set to explain my situation:

Observer best practices
I''ve seen two ways of connecting observers:
1) In the observer class put
observe MyModel
2) In the controller class put
observer :my_observer
What is the difference between these two? Also, is it necessary to put
in the observer class the following?
MyObserver.instance

test for proportion or concordance
Hello group,
my question is deciding what test would be appropriate for following question.
An experiment 'A' yielded 3200 observations of which 431 are
significant. Similarly, using same method, another experiment 'B' on a
different population yielded 2541 observations of which 260 are
significant.
There are 180 observations that are common between significant

Question about data used to fit the mixed model
Hi everyone,
I would like to ask a question regarding to the data used to fit the mixed
model.
I wonder that, for the response variable data used to fit the mixed model
(either via "spm" or "lme"), we must have several observations per subject
(i.e. Yij, i = 1,..,M, j = 1,.., ni) or it can be just one observation per
subject (i.e. Yi, i = 1,...,M). Since we have to

bad move? - complex form with *many* observe_field's
I have a pretty complex form with many text fields and a number of

the parent object and to edit the values for those associated objs, so
the form can have something like the following number of fields on the

Decoupled observers for controllers?
In the Rails Recipes book the recipe "Keeping track of who did what"
explains how to do decoupled observing of models.
In my application I''d like to do a similar thing but watching the
controllers. For example, when somebody hits the login method of the
Security controller, I''d like to make a note of it. In this case I
could observe the User model and watch for
