Selecting one row or multiple rows per ID
...ne help with coding this in R?
I need to select one row per patient i in clinic j. The data is organized similar to that shown below.
Two columns - patient i in column j identify each unique patient. There are two columns on outcome. Some patients have multiple rows with each row representing one visit, coded for in the column, visit. Some patients have just one row indicating data from a single visit.
I need to select one row per patient i in clinic j using the following algorithm:
If patient has outcome recorded at visit 2, then outcome = outcome columns at visit 2
If patient does not have vi...

Count entries in postgresql grouped by date
Hi!
I have a table with visits with a visited_at: attribute which is a datetime
field. They seem to be stored as UTC. Now I want to count all visits each
day and return something like:
{
2013-01-01: 8,
2013-01-02: 4,
2013-01-07: 9,

}
So, I did it like this which kind of works...:

(no subject)
R friends,
I am using R 2.1.0 in a Win XP . I have a problem working with lists, probably I
do not understand how to use them.
Lets suppose that a set of patients visit a clinic once a year for 4 years
on each visit a test, say 'eib' is performed with results 0 or 1
The patients do not all visit the clinic the 4 times but they missed a lot
of visits.
The test is considered positive if it is positive at the last 2 visits of that
patient, or a more lenient d...

SE of ANOVA (aov) with repeated measures and a bewtween-subject factor
Hallo!
I have data of the following design:
NSubj were measured at Baseline (visit 1) and at 3
following time points (visit 2, visit 3, visit 4).
There is or is not a treatment.
Most interesting is the question if there is a
difference in treatment between the results of visit 4
and baseline. (The other time points are also of
interest.) The level of significance is alpha=0.0179...

setting session id for first visit
I am logging web visits with a before_filter on the application
controller. The issue I''m having is that the initial visit does not
return a session id. I''m using the SqlSessionStore and the function
MysqlSession.find_session(session.session_id) to retrieve the session
id. If it doesn''t exist I...

strange has_many array problem
I have a class that has_many :visits, I want to search through the
visits to get only ones that are committed:
I thought it would be as easy as:
==================
visits.find_all do |visit|
visit.coming?
end
=================
but this always returns the entire list of visits. The only way to
get it to work is to put...

Result depends on order of factors in unbalanced designs (lme, anova)?
Dear R-Community!
For example I have a study with 4 treatment groups (10 subjects per group) and 4 visits. Additionally, the gender is taken into account. I think - and hope this is a goog idea (!) - this data can be analysed using lme as below.
In a balanced design everything is fine, but in an unbalanced design there are differences depending on fitting y~visit*treat*gender or y~gender*visit*treat...

Finding how many times was my website visited?
Hi Everyone,
Good Day!
I wanna to add to my blog a counter for displaying, how many times was my
website visited. I would like to solve it through ruby (not GA or something
like that). Is available any gem that do this task (also with checking IP
address,the time of latest visited and visited count).
Please Advice.
Thank You.

More clarification needed :) What do you mean by 'invariant need only apply
to the former'?

Not necessarily. Due to lost edges (from caller to indirect callees), a
callee node may be visited later. The analysis will just have to punt when
a special edge to 'external' node is seen.

x axis on sciplot
Is it possible to format the x axis, so that days are spaced
proportionately?
i.e. a larger space between 50 & 100, than 0 and 5?
Have not had any luck with axis.POSIXct().
Many thanks

export R-data to VisIt
Hello,
Is there anyone porting R data to VisIt (http://www.llnl.gov/visit/)?
Altough VisIt accepts 5 dozen of data formats, I can't get my data into VisIt.
I currently ran a simulation which gave me a data frame, which I wanted to import into VisIt to further explore the dataframe.
Let's say I have a data frame as follows:

"repeated"repeated measures in ANOVA or mixed model
dear List
I have a dataset with blood measurements at 5 points in TIME (0,30,60,90,120) taken on 3 VISITS (same subjects). the interest is to compare these measurements between Visits, overall and at the different time points.

Adding reference lines to xyplot
I'm trying to add a set of reference lines to a multipanel xyplot
xyplot(y ~ x | Visit,
panel = function(x, y, ...){
panel.xyplot(x, y, ...)
abline(v = c(0.5, 1))
})
However, the reference lines are different for different visits. For
example, for the first 2 visits, I'd like vertical lines at x = 0.5 and 1.
For visits 3 and four, I'd like vertical lines at x = 1 and 1....
