R "FinMetrics" Package Available?
Hello List,
I've done some cursory searching but (so far) have struck out. Does
anyone know if the R version of the S+ FinMetrics package is available?
Best,

S+Finmetrics cointegration functions
Dear all,
S+Finmetrics has a number of very specilised functions. I am
particularly interested in the estimation of cointegrated VARs (chapter
12 of Zivot and Wang). In this context the functions coint() and
VECM() stand out. I looked at package "dse1", but found no comparable
functionality. Are there any other packages you could point me to? In
general, are there efforts for

seriesMerge
Is there a function in R that is equivalent to S-PLUS's
seriesMerge(x1, x2, pos="union")
where x1, and x2 are of class timeSeries
seriesMerge is in S-PLUS's finmetrics. I looked into R's mergeSeries
(in fSeries part of Rmetrics) but I could not make it behave quite the
same. In R it expected a timeSeries object and a matrix of the same
row count. In S-PLUS when using the

fSeries
I'm trying to use garchFit from fSeries, with Student or Skewed Student conditionnal distribution. Let's say that eps (vector) is my series of daily log-returns:
data(EuStockMarkets)
eps = diff(log(EuStockMarkets[,"CAC"]))
library(fSeries)
g = garchFit(series = eps, formula.var = ~garch(2,2), cond.dist = "dstd")
s = g at fit$series
All the coefficients are ok

"R" and "S-plus"
Hi,
I apologize in advance if this is the wrong area to post this message. I would like to know if there is an "R" equivalent for the "S+finMetrics" package? I'd like to be able to use "R" to go through the examples provided in the book "Modeling Financial Time-Series with S-Plus" (E. Zivot and J. Wang). I was told that "R" and

time-series packages
Greetings,
Are there R packages that perform time-series analyses - particularly
estimation of ARIMA models along with unit-root tests? I know that
FinMetrics in the S-Plus program will do it, but I'm looking for R
packages, as well any reference material for estimating time-series'
models in R.
Thanks in advance,
David

dlm with constant terms
Hi,
I am trying to figure how to use dlm with constant terms
(possibly time-dependent) added to both equations
y_t = c_t + F_t\theta_t + v_t
\theta_t = d_t + G_t\theta_{t-1} + w_t,
in the way that S-PLUS Finmetrics does?
Is there any straightforward way to transform the above to
the default setup?
Thanks,
Tsvetan

TSeries GARCH Estimates accuracy
Hi,
I am trying to fit a GARCH(1,1) model to a financial timeseries using the 'garch' function in the tseries package. However the parameter estimates obtained sometimes match with those obtained using SAS or S-Plus (Finmetrics) and sometimes show a completely different result. I understand that this could be due to the way optimization of MLEs are done, however, I would appreciate any

Modeling inverse relationship with copula
Dear r list,
I posted this on the S list last week since i'm using some of the
FinMetrics functions on copula. Knowing there is a copula package in R,
I figure this would be an appropriate forum to ask this question.
I want to model inverse relationship between two (non-normal,
non-symmetric) marginals with the gumbel copula, or with any copula.
Say, x is lognormal and y is norm. Since

reversing perspective plot axis
Hi,
I am trying to create a perspective plot with Time on the x-axis,
Underlying Price on the y-axis, and Option Price on the z-axis. But
I don't like the way my x-axis is setup. Right now, Time is this
sequence.
Time = seq(from = 1/52, to = 1, by=1/52)
That results in the x-axis going from 0 at the back, to 1 near the
foreground corner.(If that makes any sense) I want to do the

precision problem
I have prices that I am finding difficult to compare with ==, > and >,
due to precision. For example: the numbers should match, with '==',
but they differ in the magnitude of 1e-14 due to bunch of calculations
that I run on them. Programming with java, I am used to implementing a
function that compares the difference between the numbers to a pre
determined precision factor. This

block statistics with POSIX classes
I have a monthly price index series x, the related return series y = diff(log(x)) and a POSIXlt date-time variable dp. I would like to apply annual blocks to compute for example annual block maxima and mean of y.
When studying the POSIX classes, in the first stage of the learning curve, I computed the maximum drawdown of x:

Multiple time series plots

I'm trying to plot two time series created in Rmetrics and label the
x-axis with dates. I tried the following:
dates <- as.Date(seriesPositions(x.agg))
