similar to: How to get time differences in consistent units?

Can anyone please shed any light on why R DateTimeClasses give weird times for when daylight saving time information changes, and which aren't consistent with the OS? Example: Expected result: in New Zealand DST stopped (NZDT -> NZST) at 03:00 NZDT on 2010-04-04, as confirmed by the OS time zone info (OS X 10.8.2): zdump -v /etc/localtime /etc/localtime Sat Apr 3 13:59:59 2010 UTC

Dear useRs, I'm trying to plot spray quantities against dates, and label the points on the plot. Basically quite simple, but sometimes two chemicals have been used and are listed in separate rows in the table as below; then the labels are written on top of each other. > spray SprayDate PD Trt Qwater Qai 1 2005-03-09 Spidermites Pegasus 1300 1.04 2

I have data in a file named hands.dat, which is given at the end of this question. (It's from a stats textbook example on anova). I'd like to do an aov on this, which I guess would be d <- read.table("~/hands.dat", header=TRUE) aov(Bacterial.Counts ~ Water + Soap + Antibacterial.Soap + Alcohol.Spray, data=d) but this fails. Do I need to break d$Method up into columns for

Full_Name: Bob O'Hara Version: 2.6.0 OS: Windows XP Submission from: (NULL) (88.112.20.250) Using horizontal=TRUE with boxplot() confuses it as to what is an x- or y-axis. At least, xlim= and ylim= are the wrong way round, log="x" (or "y") and xaxt= work as expected, I haven't looked at anything else. Some code to see if you can reproduce the bug (or discover

I am using R 2.2.1 on a Windows 2000 PC.

Here's a curly one. I have a share mounted via smbfs on my linux desktop. This share is on a NetApp filer somewhere, but I've also tried this on a an old linux server as well, and I have the same problem. Basically, since day light savings came into effect here (NZDT or +13), any file I create on the share gets a time creation timestamp that is way out (approximately 12 hours and 48

I'm trying to select a subset of a dataframe while dropping some factors. While the dataset gets smaller all Factor levels remain and I need to get rid of them.

Hi everybody! I recently tried out Wine, and decided to write an article about it. Well, that means I need to get some interesting windows apps working, so far it's only Notepad and Solitaire (won't make anyone cheer). The problem is, when I try to start any installer.exe file, I get some rows of nonsense ("fixme pthread...blabla") and then it exits with the message that it

Dear all - With the following code I get Boxplots and Stripcharts in one Plot: with(InsectSprays, boxplot(count ~ spray, boxwex = 0.3)) with(InsectSprays, stripchart(count ~ spray, col = "red", vertical = TRUE, add = TRUE)) But the dots from the stripchart are plotted over the Boxes. Is there any possibility to have Stripchart and Boxplots side-by-side, i.e. to move boxplots and/or

imap proxy is a "dumb proxy", it will just pass everything to google & back after you've authenticated. imapc allows you to use imap sieve to some extent.
