...found that somebody solved it by specifying a default driver in a odbc.ini file. Can somebody please tell whether this is the right approach, and if so, how to write that specification? I saw that one might do this in a ~/.odbc.ini (i.e. the user's config file) file. Best wishes, -- Sebastian Luque

Hi, When using method L-BFGS-B along with a parscale argument, should the lower and upper bounds provided be on the scaled or unscaled values? Thanks. Cheers, -- Seb

Hi, I've run into a ridiculous problem I can't find any solutions for in the archives or help pages: data(barley) cutYield <- with(barley, by(yield, variety, cut, breaks = c(0, 30, 60, 90))) As in this example, I'm using 'by' to return a factor for each level of another factor. The problem is that 'by' returns a list of the factors, and I need all these factors

...or a more complex one with additional conditioning variables (as in my actual problem). I thought I'd find something about this in the archives, but I'm either not using the right keywords or the question hasn't come up yet. Some help on how to deal with this please? -- Sebastian P. Luque

I have been lurking in this list a while and searching in the archives to find out how one learns to write fast R code. One solution seems to be to write part of the code not in R but in C. However after finding a benchmark article (http://www.sciviews.org/other/benchmark.htm) I have been more interested in making the R code itself more efficient. I would like to find more info about this. I have

...the 'subscripts' argument may be useful for the second issue, but I'm not discovering how. For the first point, I'll have to play some more with 'scales' argument and its 'at' and 'labels' components. Any suggestions? Thanks in advance, -- Sebastian P. Luque

...hs, years, etc., but not any fractions or multiples of these. Converting the chron objects to POSIXct (via 'as.POSIXct') and then using cut.Date works, but is inconvenient, as it introduces time zone information. Is there a better way to deal with this? Thanks in advance, -- Sebastian P. Luque

Hi, I'm usually confused about when to use 'slot' or '@'. I've frequently read that it's always preferable to use accessor functions, so I would think the '@' operator should be avoided. However, ?slot contains the following advise: "Generally, the only reason to use the functional form rather than the simpler operator is _because_ the slot name has to

Dear Debian R users, This is more of an apt question rather than R. I have a testing Debian system, but would like to use the unstable packages for R, *without* using the -t flag in apt-get. I think this is done by using a 'pin' rule in /etc/apt/apt.conf, but don't understand how this should be done. Can somebody provide an example please? Cheers, -- Seb
