Hello, I want to try to connect R to PostgreSQL. I have found that there are three ways: DBI or RODBC or RPostgreSQL. I tried around with DBI and RODBC but didn't get it running. In both cases I'm not clear about how to set the driver/data source. I get this error: x > channel <- odbcConnect("rtest", uid="oliver") x Warning messages: x 1: In

Hello, here I have some code, which behaves quite strange, IMHO. There is a "res.txt" which will be collected before printing it. There is a paste-statement, which has a comment at the end of the line, which is this one: "# !!!!!HERE!!!!!". If you throw out the first hash-mark "#" on that line, the printout behaves like if it is done for each of the for-loop

When I inserted one line of code, the behaviour was completely different! Instead of just printing one line more to the output, the complete call of the function in which this line was added, is different, and instead of one such

This is not a bug. Read ?paste: if you give it a vector, it will give you a vector result. That's what you're seeing.

Hello, again I'm on my weblog-script... having problems... This code: =========================== weblog <- read_weblog("web.log") weblog_by_date <- split(weblog, weblog$date) #for ( i in names(weblog_by_day) ) { print(i); print(weblog_by_day$i) } for ( datum in names(weblog_by_date) ) { print(datum) selected <- weblog_by_date[[datum]] res_size_by_host <-

Hello, what kind of advantages does R's time series offer? Would it be possible to use data with units? For example data from a real time series with certain sampling rates - could they be used so, that the sample-times are measured in millisceonds or microseconds, instead of an index of the positions? If so, this would be much easier to handle than just working with indices of a vector.

Hello, I have strings with date-/time-data from a logfile. For a sort-by-time (and other time-related analysis) I need something to convert the times to the Unix-epoche-time (better also with parts of seconds). Is there something that does that job (or a similar conversion) in R? TIA, Oliver Bandel

Hello, I don't understand the description / help-text for the numericDeriv() function. Why is there a new environment used? And what is meant with an environment here? Is it similar or the same as a local workspace, like an environment in functional languages? And why is it needed here? numericDeriv could just calculate the difference bewtween two values and divide this difference by the

Hello, a while ago I asked for collaboration support R <-> LaTeX. I got some answers, and Sweave was one, to use the Hmisc package another one. Both have their advantages and drawbacks. At the moment I would absolutely prefer Sweave, because the inclusion is done automatically, and I do not have to \include{myRTeXFile} by myself. One (THE) drawback is, that the results of commands

Hi all, does anyone know how to automatically update starting values in R? I' m fitting multiple nonlinear models and would like to know how I can update starting values without having to type them in. thank all --- On Fri, 12/26/08, r-help-request@r-project.org <r-help-request@r-project.org> wrote: From: r-help-request@r-project.org <r-help-request@r-project.org> Subject:

Hello, are there people outside who use R for analysis of wind-measurement data (meteorological or for planning of wind power stations)? Are there already scripts/modules available for analysing and displaying/plotting wind data in the way it is done in projection/planning of wind power stations? If not, would it be of interest to use R for this, and therefore adapt data-logger output to R (by

Hello, in scilab /Matlab there are functions that can create linear sequences (like R's seq()) as well as logarithmic sequences. Is there a logarithmic aequivalent of seq()? Or maybe this would be an idea for newer R-releases, maybe a type-option with "linear" and "logarithmic" as parameters....?! Ciao, Oliver

Hello, after splitting a data-frame I want to access the results. Maybe the problem is, that the factor/index is a string... ...or do I miss knowing details of the index-uasge?

Hello, what are they meaning? It could be something that would show a threshhold above which the result is indicating different meanings then just random noise. But there is no description on the definition of those lines, so it means nothing, if it is not clearly defined. Where can I find a detailed definiton? Ciao, Oliver

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, Oliver

Hello, I'm new to R (using it since about two weeks), but absolutely a fan of it from the beginning on. :-) Best tool for working with data I found. :-) I tried using the fft() and other funcitons for analysing time series. What I would be glad to have, would be a convenient way to display the complex result of a fft in a way, that real and imaginary parts each use an axis for themselves,
