I want to obtain datetime differences in mins in an other column, in front of my datetimes. I have tried this : T1 <- c("12/31/03 23:49","1/1/04 1:14","1/1/04 0:02") T2 <- c("1/1/04 0:58","1/1/04 1:16","") toto <- data.frame(T1,T2) toto y <- strptime(T1,"%m/%d/%y %H:%M") x <- strptime(T2,"%m/%d/%y

This was published on O'Reilly's site last week, but they didn't tell me until now. :) The article is pretty minimal, because I had a limited number of words to work with, so many features are not implemented. However, it's a good start. http://www.onlamp.com/pub/a/onlamp/2003/07/03/asterisk.html I had a few people review it beforehand, but I'd also welcome changes or

I have two problems for the data processing of my large data base (50000 rows). For example, a sample is as follows Num <- c(1,2,3,4,4,4,5,5) Date <- c("1/1/04 0:48","1/1/04 1:52", "1/1/04 1:55", "1/1/04 2:14", "1/1/04 3:09", "1/1/04 8:02", "1/1/04 9:05", "1/1/04 9:06") Place <-

Hi, I’m sorry, I know that it is a recurrent question but I have not been able to find the response in the Rhelp archives. I think my data require the use of the glmmPQL function but I do not know how to make the model selection. Since the AIC and log-likelihood are apparently meaningless, how can we select the parameters for a model and compare the models to find which one fits best the data?

Greetings. I have a Windows share mounted via Samba. I recently tried to rename some files; the destination filenames had some high-bit characters. The renaming had some completely unexpected consequences; the new filenames now contain the full pathname (including backslashes), plus other illegal characters (colons). The files can no longer be accessed or modified, either from the remote

I would like to compute the MC test (rfm.test) available in the package MarkedPointProcess (for the data BITOEK for example) in order to test the dependence between the marks and their locations. Why the syntax of rfm.test is false here? I have the message : ****************************** ML WARNING! Forbidden values! -- if there are too many warnings try narrower lower and upper bounds for the

Hi everybody, I was wondering if you can help me about a module. In fact, I'm looking for a package or module about Wilks' lambda criterion in R environment. I didn't find it in R website ( http://cran.cict.fr/web/packages/index.html#available-packages-W or http://search.cpan.org/faq.html). If this module exists, could you show me the command line. Thank you very much for your help,

Hi! One of the three French CRAN mirrors, cran.cict.fr (Toulouse) seems to be down most of the time, and at least really not reliable. It has currently been down for 28 days (!) [1], and I know that over two years I've rarely been able to use it (no response, slow, hangs...). I'm sure the maintainers of this mirror mean well, but the result is really negative for French R users. This

Hi there, A new thread was started on the R list about problems to upgrade R to version 2.5.1 and we were re-directed on this list. We are two with exactly the same problem and the same distribution (Ubuntu Feisty 64). We are unable to upgrade to R 2.5.1. The r-base-core package is version 2.4.1 in Ubuntu repositories while all others r-cran related packages are upgraded to R 2.5.1

Dear R users, I face to a nested pattern and despite the numerous examples in the help I am still confused. I sampled bugs in different habitats within sites which were within rivers themselves within different regions. The habitat correspond to different substrata (not systematically present in all sites). For rivers and sites, I have environemental variables (e.g. altitude and slope of

Hi, I have a question that I have not been succesful in finding a definitive answer to; and I was hoping someone here could give me some pointers to the right place in the literature. A. We have 4 sets of data, A(t), B(t), C(t), and D(t). Each of these consists of a series of counts obtained in sequential time-intervals: so for example, A(t) would be something like: Count A(t): 25,

Dear colleagues, I'm conducting a meta-analysis of studies evaluating adherence of HIV-positive drug users into AIDS treatment, therefore I'm looking for some advice and syntax suggestion for running the meta-regression using proportions, not the usual OR/RR frequently used on RCT studies. Have already searched already several handbooks, R-manuals, mailing lists, professors, but... not

Hi, I have been dreaming about a complete R environment on my USB stick for a long time. Now I finally want to realize it but what I am missing is a good, portable editor for R which has tabs and syntax highlighting, can execute code, has bookmarks and a little project file management facility pretty much like Tinn-R has those. I like Tinn-R but it seems like there is only a very old version of

Hello, I have some "stupid" problems managing "date" data. I have a colomn "date", which I converted from a character representation: for example: a="26/02/06" date=strptime(a,format="%d/%m/%y") For one part of the analysis, I'm interested only in the month and the year, so I did: m.y=strftime(date,format="%m/%y") This returns me
