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

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 <-

Dear colleague, I'd like to compute linear discriminant analysis, using R. In the book Modern applied statistic with Splus (Venables & Ripley, p. 396), lda function is used. Could you tell me where I can find this function? At what site, can I download this library ? Thank for your help.

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Hi all, What's the procedure for removing out of date cran mirrors? I've just discovered the fantastic http://cran.r-project.org/mirmon_report.html, but there 4 mirrors that have not been updated in over a month, and quite a few others that have a chequered past. Given that there are many additional mirrors available, and the poor user experience if a bad mirror is selected, perhaps

Hello dear R-help mailing list. Looks like the same issue in Russian: library(RCurl) library(XML) u = " http://www.cian.ru/cat.php?deal_type=2&obl_id=1&room1=1" a = getURL(u) a # Here - the Russian is fine. a2 <- htmlParse(a) a2 # Here it is a mess... None of these seem to fix it: htmlParse(a, encoding = "windows-1251") htmlParse(a, encoding =

Hi! I was wondering whether anybody was looking at the bugs on Bugzilla. I'm asking because I've seen bugs tackled on the mailing list quite quickly, but two fully reproducible reports I've filed on Bugzilla haven't triggered any reaction in several weeks (for the older one). FWIW, these are: - Line goes beyond plot region

Hi! When inserting R plots into a document using odfWeave, I fought for a while to get Lattice plots use the same text size as base plots. I eventually discovered that specifying a point size via e.g. svg(pointsize=10) has no effect on Lattice plots. One needs to adjust the size manually via: trellis.par.set(fontsize=list(text=10, points=8)) This is also developed for both Lattice and ggplot2 by

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 all, I know this issue has been discussed a few times in the past already, but Martin Maechler suggested in a bug report [1] that I raise it here. Basically, there is no (easy) way of printing NAs for all variables when calling xtabs() on factors. Passing 'exclude=NULL, na.action=na.pass' works for character vectors, but not for factors. > test <-

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

Hello All, Learning to use the odfWeave package. I really like the package. It has good documentation, makes some very nice looking tables, and seems to have lots of options for customizing output. There are a few things I'd like to do that don't seem to be covered in the documentation though. So I'm not sure if they're possible or not. Here's a list of some things I'd

Hi! It seems that read.table() in R 3.0.1 (Linux 64-bit) does not consider quoted integers as an acceptable value for columns for which colClasses="integer". But when colClasses is omitted, these columns are read as integer anyway. For example, let's consider a file named file.dat, containing: "1" "2" > read.table("file.dat",
