metaprogramming in controller: accessing instance variables
Hi all,
I''m trying to move a bunch of methods out of a controller into a
library that I can include and call a class method to have it
dynamically add a bunch of methods to the controller.
The goal is to just add to each controller:
include UIEnhancements::SubList
sub_list ''Note'', ''incomplete''
and have the sub_list method create all the methods

problem with chron scales in lattice
I can't get the scales parameter in xyplot of lattice to work as I
expected. I'm using R-2.1.0 and lattice 0.11-8. There should be year
labels from 1992 to 2004 for the x axis in the plot below, but instead
only a few of them appear, and in the wrong spots, as if the coordinate
system has changed after finishing with the panel function.

Array of dates/times from time.now till nextweek
Hi,
I would like to make @dates in my controller.
I tried the following:
startdate = Time.now
enddate = startdate.next_week
for enddate > startdate
@dates << startdate
startdate = startdate.tomorrow
end
But I get an errormessage when I check the syntax:
"warning: useless use of a variable in void context"
Anyone?
Thanks!
Steven.

How to extract sublist from a list?
Hi everyone,
Suppose I have a list named "lst", see below:
> lst
$sub1
...
$sub1$x
...
$sub1$y

$sub2

$sub2$x

$sub2$y

Now, I want to extract the sub-sublist $y from every sublist(sub1, sub2...)
and then storage them to a new list.
I know how to extract them by subscript or list name one by one, but I
wonder if there exist some tricks to finish this

Exclude holidays in a subset of dates?
Hi All,
I am iterating through dated materials, with variable start and end dates,
and would like to skip procedures everytime I encounter a weekend or
holiday. To do this, I thought the easiest way would be to create a
TRUE/FALSE vector corresponding to each day where it is TRUE if a workday,
and FALSE if a weekend or holiday.
So far I have been able to do this for weekdays:

Strange labels on plot with dates
Hello fellow R people,
I don't understand the default behavior of the axis labeling when
plotting dates.
I would expect something like 2001, 2002 or possibly Jan 01, Jan
02...Jan 06, but instead I only see Jan 01, Jan 01, Jan 01....
See the following example
startdate <- strptime("2001-01-01",format="%Y-%m-%d")

Kalman filter for a time series
> structSSM
Is no longer part of KFAS. All you needed to do was:
library(KFAS)
?KFAS
and you would have seen that if you went to the index. A structural state space model is now built up from its components, much like in LM. Look at;
?SSModel
