Each day the daily balance in the following link http://www. snamretegas.it/italiano/business/gas/bilancio/pdf/bilancio.pdf is updated. I would like to set up an R procedure to be run daily in a server able to read the figures in a couple of lines only ("Industriale" and "Termoelettrico", towards the end of the balance) and put the data in a table. Is that possible? If

Context: Pentium 4 with FreeBSD 5.4 and R 2.2.0 I'm trying to install the package ROracle under R. To start with I installed the oracle8- client from the ports and referred to it via the variable $HOME_ORACLE as /usr/local/oracle8-client. Then I started R. After issuing install. packages("ROracle") R downloaded the needed package and started to compile it but complained:

...sql.h, sqlext.h headers problem and a successive problem with the SQLTables libraries. This set things straight and RODBC was compiled flawlessly. I think it would be worth your while adding this piece of information in the README file.

Perhaps I'm missing a real, stupid point but I can't understand the following behaviour: > strptime("30 march 2008 02:30 AM",format="%d %B %Y %I:%M %p") [1] "2008-03-30 02:30:00" > strptime("30 march 2008 00:30 AM",format="%d %B %Y %I:%M %p") [1] NA Why times 00:nn are not available and how solve this?

At office I have been introduced by another company to new, complex energy forecasting models using gams as the basic software. I have been told by the company offering the models that gams is specialised in dealing with huge, hevy-weight linear and non-linear modelling (see an example in http://www.gams.com/modtype/index.htm) and they say it is almost the only option for doing it. I would

Dear All, I'm happily extracting data of temperature from an oracle db under R via RODBC. After manipulating the extracted data I put them into a data.frame 'dati' which is as follows: > dati DATA tm.

Till yesterday I was more than satisfied by RODBC, specifically by sqlSave which I had been happily using in a daily crontab R batch job regularly updating a postgresql db for as long as one year. In this R- batch I was able to save records into indexed tables *** even though *** they already existed. in this case sqlSave simply neglected those rows of the input table that were offending the
