Hi,
I have recently downloaded RSQLite with intention of using it to access
googlecalendar data stored in Thunderbird cache.sqlite and
local.sqlite. Thunderbird exports the data just fine as a .ics file
but when I access it directly from R using RSQLite function dbGetQuery
I get strange
Microsoft Access and Excel [for which RODBC seems to
require R 32 bits] from within my 64 bits version.
Thank you in advance,

Dear all,
I can't seem to run what seems (to me!) like a common SQL statement in RODBC:
data - sqlQuery(a, 'SELECT TO_CHAR (DB1.DATE, '') year FROM DB1')
In contrast,
data - sqlQuery(a, 'SELECT TO_CHAR(DB1.DT_INICIO) year FROM DB1')
works but it does not come up as I want it to
(pattern=a)
a specific value, e.g., 99, without having to assign each object at a time.
is there a way I can do this within a for cycle? I have tested several eval
and parse statements but with no success.

Hi,
I seem to recall coming across a function that allowed one to mouse-click on an
xy-plot and obtain x and y coordinates. Can anyone remind me its name?
Thanks,

the MA case as I do in the AR case?

Stoffer and Shumway have a nice hands-on book on time series with R.
Their website is also very instructive. You may also wanna take a look
at the tseries, FinTS and forecasting packages.

Dear colleagues,
“arima” returns directly the 1-step ahead errors but I am interested in
obtaining other h-step ahead errors for several ARIMA models I have
fitted. Is there any way I can obtain this with R? Any help would be
appreciated.
Sincerely,
Nuno Prista
I have looked at the predict.Arima and its a fact that it returns the
s.e. for several steps ahead. What I was wondering was if there was a
way to access to the h-step ahead fitted innovations that underlie them.

Dear colleagues,
I am new to R and statistics so please keep that in mind.
I have doubts on the df calculation of Ljung-Box test (Box.test). The
function seems to use always the df=lag=m and not df=m-p-q like suggested in
Ljung and Box (1978) paper (that is referenced).
Do you agree

Hi,
I am studying frequency the seasonal cycle of a time-series that I believe

Hi,
Hope this does not sound too ignorant .
I am trying to detrend and transform variables to achieve normality and
stationarity (for time series use, namely spectral analysis). I am using the
boxcox transformations.
As my dataset contains zeros, I found I need to add a constant to it

Hi,
I have been having trouble finding references that compare the classical
decomposition methods [decompose()] with the STL method of
Cleveland et al. (1990) [stl()].
Can anybody indicate some references that make comparisons between the two
methods and the advantage/disadvantages of each one
for something more than this :). Can anybody supply me with some references
that may make comparisons between the two methods and/or discuss the
advantage/disadvantages of each one in different situations?
Thanks in advance,
Nuno Prista
