Dear all, In RW0901 I could > dates("01/01/2000") [1] 01/01/100 where only the printing was wrong, but the double numeric representation of the chron object was calculated correctly but now in RW0990 > dates("01/01/2000") Error in fun(yy, ...) : must be 2-digit (numeric) year specification and also the followig doesn't help > dates("01/01/2000",

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 <-

Subject command doesn't work with rw0901 running on win95 (of course) so, after looking at the vi and emacs code, I put textpad <- function(name = NULL, file = ""){ edit(name, file, editor = "g:\\textpad\\txtpad32.exe") } Now x <- textpad() brings up the botched code in the textpad editor, as expected, but when I try to save changes I get an "Access to

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

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.

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.

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 list, I ran into a strange behaviour of the pnbinom function - or maybe I just made a stupid mistake. First thing is that pnbinom seems to be very slow. The other - more interesting one - is that I get two different curves when I plot the estimated density and the density given by pnbinom. Shouldn't it be the same? This is only the case, I think, if I use the parameter size = 1. I

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, I just installed version 2.11.1 on my Mac OS X 10.5.2.

Dear Rusers, I tried to implement a function comparing mean scores between one subject (the patient) and a group a control subjects. The function returns attended results, but I also obtained the following warning : Warning message: the condition has length > 1 and only the first element will be used in: if (substr(fp, 1, 1) == "<") fp else paste("=", fp) Maybe

I have succeded in defining the cdf of the generalized beta of the second kind, eg. pgbeta2 <- function(quint,b,a,p1,p2) { integrate(function(x) {exp(log(a)+(a*p1-1)*log(x)-(a*p1)*log(b)-log(beta(p1,p2))-(p1+p2)*log(1+(x/b)^a))},0,quint)$value } but I'm facing problems with the quantile function. I tried something like qgbeta2 <- function(proba,b,a,p1,p2) { optimize(function(z)
