decomposed.ts class and method
Dear R People:
In the function "decompose", the object has the class of "decomposed.ts".
(from package stats)
I would like to see the class definition and the method for the plotting.
However, when I use
isClass("decomposed.ts")
I get "FALSE".
When I check getMethods("plot")
there is no method for plot on decomposed.ts
Any suggestions,

Proposed modification to decompose() and plot.decomposed.ts()
The decompose() function truncates the seasonal component
unnecessarily. I've modified the function to fix this problem, and
also added the original data to the object returned (to enable better
plotting).
I've also modified the plot.decomposed.ts() function so that it plots
the original data in the top panel rather than the reconstructed data.
The difference between the two is that the

ts; decompose; plot and title
Is there any way to give a "decent" title after I plot something
generated by decompose?
For example:
# generate something with period 12
x <- rnorm(600) + sin(2 * pi * (1:600) / 12)
# transform to a monthy time series
y <- ts(x, frequency=12, start=c(1950,1))
# decompose
z <- decompose(y)
# plot
plot(z)
Now, the title is the ugly "Decomposition of additive time

stats::decompose - Problem finding seasonal component without trend
Hi R-help,
I'd like to extract the seasonal component of a short timeseries, and was
hoping to use stats::decompose. I don't want to decompose the 'trend'
component so I thought I should call decompose(x,filter=0). I think I've
either misunderstood the filter argument or come upon a bug/feature in
decompose.

igraph: decompose.graph: Error: protect(): protection stack overflow
I just got this error:
> library(igraph)
> comp <- decompose.graph(gr)
Error: protect(): protection stack overflow
Error: protect(): protection stack overflow

what can I do?
the digraph is, indeed, large (300,000 vertexes), but there are very
many very small components (which I would rather not discard).
PS. the doc for decompose.graph does not say which mode is the default.

decomposing decompose(), issue?
Hi
I'm just stepping through the decompose() function, in "stats". Does
this contained line of code not work if you have a time series ending
"unevenly" (i.e., middle of the year), or am I missing something?
season <- na.omit(c(as.numeric(window(season, start(x) +
c(1, 0), end(x))), as.numeric(window(season, start(x),
start(x) + c(0, f)))))
The line seems to

Decompose function : calculation of each component
Hello,
I'd like to know how R does calculate each component in the decompose()
function?
More precisely, how is calculated the final trend component in this
function?
Thanks for your answer

regarding changing of title of decompose graph
Hi All,
I am new to this forum. I have just started learning R. When i use
plot(decompose(x)), i am getting the title " Additive time series
decomposition". How to make this title off and change to some other title.
Any help regarding this is highly appreciated.
With sincerer regards,

Using igraph: community membership of components built by decompose.graph()
Hi everyone!
I would appreciate help with using decompose.graph(), community
detection functions from igraph and lapply().
I have an igraph object G with vertex attribute "label" and edge
attribute "weight". I want to calculate community
memberships using different functions from igraph, for simplicity let
it be "walktrap.community".

decompose a correlation matrix
Is there a simple way to decompose the upper triangle
of a correlation matrix to a linear list;
For example:
X Y Z
X 1 2 3
Y 2 1 4
Z 3 4 1
so you get a list like:
xy 2
XZ 3
YZ 4
I suspect you can do it with a matrix transformation, but
that beyond me at present.
Many thanks

Specify custom par(mfrow()) layout for defined plot()
Dear R Users,
I am doing stats::decompose() on 4 different time series. When I issue
csdA <- decompose(tsA)
plot(csdA)
I get a summary plot for observed, trend, seasonal and random components
of decomposed time series tsA. As I understand it, the object returned
by decompose() has it's own plot method where mfrow(4,1) etc. is
defined. Now suppose I wanted to wrap those mfrow(4,1) into

split/decompose lines
Dear R users,
I have a very simple problem but I can't find the function in R to deal with
it.
I need to split (or decompose) one line into many lines using one field as a
reference.
I have a table with the following format:
A B Frequency
23 3 2

And need to split each line into several lines according to the frequency to
achieve something like this:

[LLVMdev] structs get decomposed when shouldn't
Hi all,
I'm new on the list, so I want to say hello for everybody!
I'm from Hungary and writing a LLVM backend for Tile64 processor as my
master's thesis. It's a big time pressure on me, so the thesis will
probably describe a backend only providing an assembly printer, but the
development is likely to be continued beyond the thesis.
For now, I've run into a very annoying

[LLVMdev] Is there pass to break down <4 x float> to scalars
Hi, Richard,
Your decompose vector patch works perfect on my site. Unfortunately, I
still get stupid code because llvm '-dse' fails followed by
'decompose-vector' .
I read the DSE code and it is definitely capable of eliminating unused
memory stores if its AA works. I don't think basic AA works for me. I
found my program have complex memory accesses, such as bi-dimentional

Help with STL function to decompose
Hi everyone.
I'm having some troubles with STL function to decompose some data.
My issue is that I have monthly data from September 2005 up to August 2010
