search for: adates

Buenas tardes a todos, tengo un problema con R: ejecuto el mismo script en el ordenador del trabajo y en mi portátil con los mismos datos y obtengo resultados diferentes (siendo los correctos, los obtenidos en el trabajo): rm(list=ls()) directorio<-"C:\\Documents and Settings\\BDs\\" library(RODBC) library(car) library(gdata) ### DATOS A ###

First time to post and searched archive for this problem with no clue. My version is 2.5.1. Below is a function to check if a given date is a valid date to a given date function object. It uses try (also tried tryCatch but with same problem). When given an invalid date, I am hoping try will generate en error message which would be picked up by the geterrmessage and thus expecting a false result.

I've been trying to understand the as.Date functionality and I have a date and time stamp field that looks like this: "Tue Sep 15 09:22:09 -0600 2009" and I need to turn it into an R Date object for analysis. Simple date conversions I have down, no problem: > adate = c("7/30/1959") > as.Date(adate,"%m/%d/%Y") [1] "1959-07-30" > But when it

Hi, I've got a problem with RODBC and saving (sqlSave) of a dataframe in Access. R 2.0.1 is running on windows XP. When executing the examples in R help for the "USArrests" data set "sqlSAve" works fine, but running sqlSave() for a dataframe "Adat" > str(Adat) `data.frame': 1202 obs. of 18 variables: containing 18 columns and ca. 1200 rows fails.

Dear R People: I'm working with R-2.14.0 created from source on a quad core Windows 7 machine. Starting yesterday, nearly everything I run just sits. When I hit escape or Ctrl C, nothing happens. Has anyone run into this, please? Any suggestions would be much appreciated. Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of

Hi all, I've searched this problem and still I can't understand my results, so here goes: I have some time series I've imported from excel with the dates in text format from excel. Data was imported with RODBC, sqlQuery() function. I have these dates: >adates [1] "01/2008" "02/2008" "03/2008" "04/2008" "05/2008" "06/2008" "07/2008" [8] "08/2008" "09/2008" "10/2008" "11/2008" "12/2008" "13/2008" "14/2008" I want t...

Hi, I''m trying to create a method to return a random date within a range. So far, I''ve come up with this... require ''parsedate'' def random_date (a, b) adate = ParseDate.parsedate(a) bdate = ParseDate.parsedate(b) atime = Time.local(*adate) btime = Time.local(*bdate) atime + (rand * (atime - btime) ) end ...and it doesn''t seem to

This patch (to OpenSSH 3.0.2p1) adds support for using krb4, krb5 and other principal names in authorized_keys entries. It's a sort of replacement for .klogin and .k5login, but it's much more general than .k*login as it applies to any authentication mechanism where a name is associated with the ssh client and it supports name patterns and all the normal authorized_keys entry options

Hi R community I copied a bit of my R code that gets some data from a database. You won't be able to run the code, but I am a beginner so you will probably understand what going on. I would like to make a variable I can refer to inside the sqlQuery. Instead of writing the start date and time (ex SP.lokaldatotid >= '2005-01-01 00:00:00') inside the query I would like to define it

Hi all, This is a really basic question but I can't figure it out. I am trying to write a piece of code that will  use two datasets, z and m.. This code is meant to assign the mean of selected values in dataset m to a new column z$c in datset z but the rows and columns of the two data sets differ. I managed to write this down but think I am missing something standard but basic,I will really

Looking for a (windows) app. that will listen to the manager interface then pop-up a web browser pointing to a page on an incoming phone call.. Not looking for outlook integration, or outbound dialling, just to recognise an incoming call and poke a URL at a website in a browser and I've absolutely no idea how to do it in the MS windows world... Any clues appreciated.. (More pointing to an

Preamble: I''ve been putting off getting into testing while I got my head around everything else, because I am a BAD PERSON, and thought they wouldn''t be fun. After the past couple of hours I know I was wrong to put it off and right that they wouldn''t be fun (Didn''t help that took me a while to realise the Agile Book is out of date on unit testing). Anyway I

Create a virtual FAT-formatted floppy disk from a directory of files. For example: nbdkit floppy /path/to/directory The implementation of this is quite different from nbdkit-iso-plugin since we cannot use an external program. Instead this plugin synthesizes the MBR partition and FAT32 structures that are required. To do: Implement bootable virtual floppy using syslinux. This is not

R experts, How could I extract the week number from a date vector (in Date class) such that week numbering (week 1...2...) begins (May 01) and ends (October 31) on the same specific dates each year? Week numbering must conform to the following day numbering format (Sat=1,Sun=2,Mon=3.....Fri=7). This means that new weeks must begin on Saturdays, and end on Fridays (except for the first date

Add nbdkit-floppy-plugin, “inspired” by qemu's VVFAT driver, but without the ability to handle writes. The implementation is pretty complete, supporting FAT32, LFNs, volume labels, timestamps, etc, and it passes both ‘make check’ and ‘make check-valgrind’. Usage is simple; to serve the current directory: $ nbdkit floppy . Then using guestfish (or any NBD client): $ guestfish --ro
