decide between polynomial vs ordered factor model (lme)
Dear alltogether,
two lme's, the data are available at:
http://www.anicca-vijja.de/lg/hlm3_nachw.Rdata
explanations of the data:
nachw = post hox knowledge tests over 6 measure time points (= equally
spaced)
zeitn = time points (n = 6)
subgr = small learning groups (n = 28)
gru = 4 different groups = treatment factor
levels: time (=zeitn) (n=6) within subject (n=4) within smallgroups

FIX for old and new problems with order(): order fails with na.last=NA (PR#1981)
I recently reported order() to ignore decreasing=TRUE with na.last=NA.
Now I discovered two other problems and send corrected code.
Best regards
Jens Oehlschlägel
# PROBLEM 1 see PR#1906
# PROBLEM 2
> order(1, na.last=NA)
Error in apply(sapply(z, is.na), 1, any) :
dim(X) must have a positive length
# clearly wrong as
> order(1)
[1] 1
# is defined
# PROBLEM 3

silk_warped_autocorrelation_FIX() NEON optimization
Hi all,
I'm sending patch "Optimize silk_warped_autocorrelation_FIX() for ARM NEON" in an separate email.
It is based on Tim’s aarch64v8 branch https://git.xiph.org/?p=users/tterribe/opus.git;a=shortlog;h=refs/heads/aarch64v8
Thanks for your comments.

loop function within a loop
Hi all,
I'm working on a loop function for a large dataset which contains 1000
different groups. I would like to reconstruct the order of events within
each group by using a loop function in R. (Currently the order of events are
based on the ascending order of prev_event within the group)
A demo data frame:
event prev_event group
845 0 5360

[newb] Find vs Find :all question
I''m playing out with writing an online store.
So far it has accounts, addressbooks, and orders, and those 3 are tied
together with an customer ID. I also have orderDetails, which are
associated to the order via an order number. See models below...
When I do the following I can access the orderDetails information just
fine:
@order = Order.find(params[:id]) # i pass it a customer

apply and sort vs vectorized order
Dear all,
Trying to solve a problem I had (see thread "putting NAs at the end" )
I've noticed a difference in system time requirements between using apply
and sort (or order)
to order each row or column of a matrix compared to a vectorized function I
wrote.
Using apply is much faster when the number of loops (number of rows or
columns to order) is low BUT
much slower when number of

Combining imputed datasets for analysis using Factor Analysis
Dear R users and developers,
I have a dataset containing 34 variables measured in a survey, which has
some missing items. I would like to conduct a factor analysis of this
data. I tested mi, Amelia, and MissForest as alternative packages in
order to impute the missing data. I now have 5 separate datasets with
the variables I am interested in factor analysing. In my reading of the

Specify attr_protected
This is kind of a two part question.
Question One: I want to be sure that an Order model is protecting
sensitive attributes from mass assignment.
The example looks like this:
describe Order do
it "should protect total attribute from mass assignment" do
@order = Order.new(:total => 0.05)
@order.total.should_not == 0.05
end
end
And the code to implement it:

[LLVMdev] [LSR] hoisting loop invariants in reverse order
It's not caused by "the insertion point is set to the default after".
I should mention the reason somewhere earlier. "Reversing the order of
arg0~3 is not intentional. The user list of pixel_idx happens to have
pixel_idx+3, pixel_idx+2, and pixel_idx+1 in this order, so LSR simply
follows this order when collecting the LSRFixups."
I'm not an expert on uselist orders,

Saving one-many associations (elegant solution please)
What is the most elegant way to save new one-many associations?
order = Order.new(:name => "My Order")
order.line_items << LineItem.new(:product_id => 1, :quantity => 2)
order.line_items << LineItem.new(:product_id => 2, :quantity => 5)
order.save
The above - which is by far the most elegant way of putting it - doesn''t
work for me - the line_items

I don't understand the 'order' function
I thought I've understood the 'order' function, using simple examples like:
order(c(5,4,-2))
[1] 3 2 1
However, I arrived to the following example:
order(c(2465, 2255, 2085, 1545, 1335, 1210, 920, 210, 210, 505, 1045))
[1] 8 9 10 7 11 6 5 4 3 2 1
and I was completely perplexed!
Shouldn't the output vector be 11 10 9 8 7 6 4 1 2 3 5 ?
Do I have a damaged

bar order using lattice barchart()
Dear List,
I am want to plot my data in increasing order using the lattice barchart() function. I used order() to put my data in the order I want, but when I plot it I get the original order of the data. I think this has to do with the row index number since order() does not re-number the rows in the new order but instead keeps the original row numbers and puts them in a different order. For

Strange Problem With Unwanted, Transient Caching
Hello,
I hope somebody can explain to me what''s going on here because I''m
baffled!
In a controller''s action I want to create a new order for a
customer. Because I post back to the same action (not RESTful I
know, but that''s for another day) I use code like this:
def edit
@order = Order.find_by_id(params[:id]) || Order.new

Reorder in decreasing order
reorder() is probably the best way to order the levels in a vector
without manually specifying the order. But reorder() orders by default
in an increasing order: "The levels are ordered such that the values
returned by ?FUN? are in increasing order."
Is there a way to do what reorder() does, but order the levels
according to a _decreasing_ order of the values?

'ordered' destroyed to 'factor'
Dear all,
?
I don't know if you consider this a bug or feature, but it breaks reasonable code: 'unlist' and 'sapply' convert 'ordered' to 'factor' even if all levels are equal. Here is a simple example:
o <- ordered(letters)
o[[1]]
lapply(o, min)[[1]]??????????# ordered factor
unlist(lapply(o, min))[[1]]? # no longer ordered
sapply(o, min)[[1]]??????????# no

"Overriding" association build methods
Hey everyone
I have (in a nutshell) two models: Customer and Order. Customer
has_many Orders and Order belongs_to Customer. The Order model
contains fields such as name, address and phone that mirror the
associated Customer''s fields at the time the order was placed. The
reason for this is that if the customer changes their details then the
order contains the details that were current

inverse function of order()
I have:
d <- sample(10:100, 9)
o <- order(d)
r <- d[o]
How I can get d (in the original order), knowing only r and o?

[LLVMdev] [LSR] hoisting loop invariants in reverse order
Hi,
I was tracking down a performance regression and noticed that
LoopStrengthReduce hoists loop invariants (e.g., the initial formulae of
indvars) in the reverse order of how they appear in the loop.
This reverse order creates troubles for the StraightLineStrengthReduce pass
I recently add. While I understand ultimately SLSR should be able to sort
independent candidates in an optimal order,

HABTM problem not saving all associations
Hello all,
I have an Order object that has and belongs to many Products and has
and belongs to many Loan Types. This is so I can select multiples of
each in my order entry screen via checkbox groups.
I''m having some trouble with saving multiple HABTM associations for a
single model object; only the first HABTM association declared in the
model will save during the initial @order.save
