understanding time series objects
### First, is there a way to access a univariate time series as a matrix
instead of a vector?
# For example:
data(UKLungDeaths)
# If I do
apply(mdeaths,1,cumsum)
# Gives an error as mdeaths is not a matrix but a vector, although when I
look at it :
mdeaths
# the ts object has a matrix like "appearance"
# The only way of doing it I've found is:
mdeaths2<-as.matrix(mdeaths)

dygraphs, multiple graphs and shiny
Hi All:
This is really getting into the weeds, but I am hoping someone will have a solution. I am trying to use dygrahs for R, within Shiny.
The situation arises when I am combining a number of dygraphs into one plot. If I am just in an RNotebook, if you look at:

Barplot errors in MASS script

examples both in the book and in ../lib/R/library/MASS/script, I'm now trying

multiple scale
Hi all
i need to put on one graph 2 functions who's x axis is the same and y not.
I mean on horizontal the time, and on vertical left: pressure, on vertical right: rpm of a motor, is R able to do that?
i've found this that i could adapt maybe (i don't need time series really?) :/ :

How to pass function argument of same name to internal call?
I ran across this problem when playing with ccf().
Its function call is
>function (x, y, lag.max = NULL, type = c("correlation", "covariance"),
plot = TRUE, na.action = na.fail, ...)
Internally, ccf() calls plot(), which digs up plot.acf() whose default
style is type='h' .
I wanted to pass the argument type='l' to the plotting routine, but of

acf() plots of a data.frame: what meaning?
Hello,
what is the meaning of the plots of an acf()-plot,
when using a data frame as argument?
The result is NOT obvious for me.
There are combinations of the columns of a dataframe in the reulting
plot.
But an acf() is just defined for onyl one time-sreies.
So what do the plots mean? I did not found a description in the
help-page.
Ciao,

"ccf versus acf"
I am trying to run a cross-correlation using the "ccf()" function. When
I select plot = TRUE in the ccf() I get a graph which has ACF on the
y-axis, which would suggest that these y-values are the auto-correlation
values.
How should I adjust the code to produce a plot that provides the
cross-correlation values?
Here is my code:

Lineair regression modelling between time series //correlation analysis
Dear R specialists,
I'm working with time series and want to investigate the relationship
between two time series by correlation analysis or by fitting a gen.
lineair model to the plot of x(timeserie1) and y(timeserie2).
Lin1 <- data.frame(
Nr = c(1:lengte),
NDII = window(ts.mNDII,c(1998,10),c(2003,11)),
InvERC = window(Inv.ERC,c(1998,10),c(2003,11))

(no subject)
can you recommend a good manual for R that starts with a data set and gives
demonstrations on what can be done using R? I downloadedR Langauage
definition and An introduction to R but haven't found them overly useful.
I'd really like to be able to follow some tutorials using a dataset or many
datasets. The datasets I have available on R are

'Apparently' trouble with name spaces and Sweave...
Ben Bolstad experienced something odd while running R CMD check over
a package of ours using r-devel (yesterday's fresh).
He tracked down the problem to a vignette calling 'library(MASS)'.
Please kindly ignore if this is a known (and temporary) issue.

Computing fundamental harmonics from a periodogram
Dear all,
I'm trying to finding the fundamental harmonics (ie. peaks in a
periodogram) from a time series (extracted from an mp3). For example,
if I look at
spectrum(fdeaths, spans = c(3,3))
I'd say the fundamental harmonics are about 1, 2, 3.5 and 4.5 - but
how can I extract these automatically? (preferably with some
heuristic for choosing the smoothing spans too)
I'm aware of

Preliminary version of ts package
There is now a preliminary version of a time series package in the R-devel
snapshots, and we would welcome feedback on it. It is based in part on the
packages bats (Martyn Plummer) and tseries (Adrian Trapletti) and in part
on code I had or have written. (Thanks for the contributions, Martyn and
Adrian!) Some of the existing ts code has been changed, for example to plot
multiple time series, so
