A new version of the chron add-on package is now available from CRAN. The previous version introduced code to ensure that chron would work correctly in the 21st century. Of course, the main issue is how to deal with 2-digit dates.

R-users: Can someone tell me how to obtain the date and time an object was last modified in R? I'm using version 1.1.1 for Windows. thanks -- Jack Lewis Redwood Sciences Laboratory 707-825-2929 voice Pacific Southwest Research Station 707-825-2901 fax USDA Forest Service jl7001 at axe.humboldt.edu

Forgive me, but while I find the documentation for initially installing R to be clear, I'm not so happy about updating. I want to update from R 1.2.1 to R 1.2.2 (mainly so I can get the debugged version of pictex() ). Now I have downloaded the base zip files, say to Z:\Program Files and my existing installation of R 1.2.1 is sitting in Z:\Program Files\rw1021. Running rwinst.exe I need to

Hello: I am brand new to R, though I've used S-Plus for some time. I've developed some specialized plotting functions that I want to distribute and would like to provide users with a dialogbox for entering input arguments. Has anyone developed functions in R for displaying dialogboxes that could accept multiple inputs? I found winDialog and winDialogString, but these only accept and

hi all- after a but of hacking with msys and mingw i think i''ve compiled an easy to install version of the rb-gsl bindings. for those of you who don''t know what these are, the gnu scientific library (gsl) is by far the best collection of open source algorithms for scientific computing available. you can read about the gsl and ruby bindings to it here

R-community-- Is there a contributed package (or does anyone have code otherwise) for exact inference tests and resampling statistics ala' StatExact? I've perused the package descriptions on CRAN and didn't see anything, but since several contain many functions, I thought perhaps I'd ask. --Mike C. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Michael

Hi all, I'm using R0.99a on WinNT4. I downloaded a bunch of packages and tried using Rinst.exe to install them. For whatever reason, Rinst.exe does not find all the packages I downloaded. I put all files in the same temp directory, but Rinst only finds some of them. I have no problem installing the rest with WinZip, but if Rinst works it would be much easier (don't have to run WinZip

Full_Name: Rick Bilonick Version: 1.6.0 OS: Linux (RH 7.1) Submission from: (NULL) (12.4.226.1) Hi. I'm using Red Hat 7.1 Linux (Intel 586). I installed the 1.6.0 rpm. No problems were reported. When I tried to load the chron library: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "/usr/lib/R/library/chron/libs/chron.so":

Hi list, I have some questions regarding 1) conversion of date + time characters to chron 2) formatting chron object printing Regarding (1), Gabor's Rnews 2004 4/1 article has been indispensible, but I often work with files where dates and times are contained in a single field. In this case, I would like to control input/output of chron objects when each observation of date and time is

Running R 2.13.1 on Windows XP. I would like to get week of the year (1-52) for each date. library(chron) dts <- dates(c("02/27/92", "02/27/92", "01/14/92","02/28/92", "02/01/92")) dts dts.chron <- as.chron(dts) dts.chron class(dts.chron) # all of these component extractions work: months(dts.chron) weekdays(dts.chron) years(dts.chron)

R-devel team-- Will the patches that Brian Ripley has posted be rolled into the main R-win distribution on CRAN? I ask because I'm going to be using R in one of my ecology courses during fall semester, and although I'll probably give the students a CD with R and a variety of other tools bundled onto it, I'll also tell them where to upgrade and look for additional packages and other

I've been experimenting with R during the last week and I thought I'd pass on some comments on issues on the documentation that left me a bit confused. To start with (literally), the ReadMe.rw1021 file says that the easiest way to install R is to download the rwinst.exe installer program. That gave me the impression that the program would connect to an R download site, download the

I have two local variables: startTime and expectedStartTime. Both are chron related objects. When I look at the class for the objects I can see they are of class "times". When I print them to the console, they both read: "09:30:00" When I print them as.numeric(), they both read: 0.3958333 When I try and compare them: (as.numeric(startTime) == as.numeric(expectedStartTime)) it

Here's a question for ecologists on the r-help list-- I'm addressing this to ecologists in particular because they're most likely to be familiar with the equation in question but I'll be happy to discuss the problem with anyone who's willing to take a whack at it. I'm trying to write a function to calculate the large sample variance of species richness estimates by

Hi! I am new to R. I want to install "packages" from Package Sources in the web. I follow the instruction and use the "install.packages" but no luck. Here is what I did: > install.packages(gss,"C:/R/rw1021/library", CRAN = options("CRAN"), contriburl = contrib.url("http://cran.r-project.org"),

I can't get the scales parameter in xyplot of lattice to work as I expected. I'm using R-2.1.0 and lattice 0.11-8. There should be year labels from 1992 to 2004 for the x axis in the plot below, but instead only a few of them appear, and in the wrong spots, as if the coordinate system has changed after finishing with the panel function. library(chron) library(lattice) # vertical grid

I was just looking for an easy way to convert between COM datetime and chron datetime (both ways.) I found examples on the list, but they involved origin. Does anyone have functions for converting COM datetime <-> chron datetimethat work "safely"? David L.

Hey R folks, i found some strange (to me) behaviour with chron to POSIXct conversion. The two lines of code result in two different results, on ewith the correct time zone, one without: library(chron) as.POSIXct(chron('12/12/2000'), tz = 'UTC') as.POSIXlt(chron('12/12/2000'), tz = 'UTC') Only the code below would give me a POSIXct object with the correct time

Dear Michael Camann, My concern was after having a hetero-computing environment for many years, I found that I had to keep an old version of Microsoft Windows based applications to be able to interact with my constituents. This at times can become very expensive. I have had to limit my budget on the UNIX/Linux platform to compensate for Microsoft Windows based applications. With Open Office
