creating and populating an environment
Hi, I often work with R by writing long(ish) Excel-VBA macros
interspersed with calls to R via RExcel. A typical example of this would
be:
Sub VBAMacro()
'fetch some data from an excel sheet
'do some basic stuff on said data
'transfer data from vba to R
'run some R statements
'get data back to vba
'show results on the excel sheet
'clean R by deleting all vars

"Holes" in a data frame with time intervals
Good morning,
I am facing a problem very easy to solve with a program, but not too
easy (at least IMHO) with a "declarative" approach.
I have a dataframe df with some information about bank branches with a
validity time associated (start date/end date, format YYYY-MM-DD) to
some attributes (for example number of employees assigned).
The following example will clarify this

Data frame "pivoting"
Dear R experts,
I am trying to solve this problem, related to the possibility of
changing the shape of a data frame using a "pivoting-like" function.
I have a dataframe df of observations as follows:

A1 2007 P1 V1
A1 2007 P2 V2
A1 2007 P3 V3
A1 2008 P1 V10

R: Securities earning covariance
Good morning.
I have a real fuzzy question to ask; we have a calculation engine which
is composed by n virtual machines each of them with a jvm 2GB of memory
on Linux Red Hat each of them with the "R" package which comes along
with the Red Hat Linux distribution.
We have now to increase the number of "nodes" trying to avoid to use new
virtual or physical machines. So my

Agreggating data using external aggregation rules
Dear R experts,
I am currently facing a tricky problem which I have read a lot about in
the various R mailing lists without finding exactly what I need.
I have a big data frame DF (about 2,000,000 rows) with 7 columns being
variables and 1 being a measure (using reshape package nomeclature).
There are no "duplicates" in it.
Fot each of the variables I have some "rules" to

Compress (gzip) a pdf device
I have not found an easy way to compress a file on filesystem.
Especially I'd like to compress a pdf from pdf() function/device. Is it possible to compress It on the flight?
I'd like to do something like:
pdf(gzipconnection())
dev.off()
If It is not possible, how can I create a gzip with the pdf?
Thanks

first of all I apologize for not having changed the object.

and at the end of the process extracts calculated data from R.
The question is: can I

Logging AD domain name in access.log
Hi to all.
Using Samba 3.0.22 on 2 identical systems (SLES 10).
On the first system, Samba logs correctly AD domain name and user in the form DOMAIN+username in access.log.
On the second one, it logs only the username, stripping away the domain name.
The only difference is that the first system is part of a network with a w2003 server acting as a domain controller, while the second machine talks

How to save a model in DB and retrieve It
I'm wondering how to save an object (models like lm, loess, etc) in a DB to retrieve and use it afterwards, an example:
wind_ms <- abs(rnorm(24*30)*4+8)
air_kgm3 <- rnorm(24*30, 0.1)*0.1 + 1.1
wind_dg <- rnorm(24*30) * 360/7
ms <- c(0:25)
kw_mm92 <- c(0,0,0,20,94,205,391,645,979,1375,1795,2000,2040)
kw_mm92 <- c(kw_mm92, rep(2050, length(ms)-length(kw_mm92)))

ARIMA, AR, STEP
Here is my problem:
Autoregressive models are very interesting in forecasting consumptions (eg water, gas etc).
Generally time series of this type have a long history with relatively simple patterns and can be useful to add external regressors for calendar events (holydays, vacations etc).
arima() is a very powerful function but kalman filter is very slow (and I foun difficulties of estimation)

Optimise huge data.frame construction
I have data for different items (ID) in a database.
For each ID I have to get:
- Timestamp of the observation (timestamp);
- numerical value (val) that will be my response variable in some kind of model;
- a variable number of variables in a know set (if value for a specific variable is not present in DB it is 0).
To get to the above mentioned values I have to cycle

R: Confidence Intervals for logistic regression
a closer look to the help on predict.glm will reveal that the function
accepts a 'type' argument.
In you case 'type = response' will give you the results in probabilities
(that it seems to be what you are looking for).
There also is an example on use of the 'type' argument at the end of the
page.
