I've recently stumbled across data.table, Matthew Dowle's package. I'm impressed by the speed of the package in handling operations with large data.frames, but am a bit overwhelmed with the syntax. I'd like to express the SQL statement below using data.table operations rather than sqldf (which was incredibly slow for a small subset of my financial data) or import/export with a

Hi, I have a few dates coming from the datebase in the format ''DD-MM-YYYY'' How can I change this in to a more human readable format? such as 1st July 2006 Thanks Scott -- Posted via http://www.ruby-forum.com/.

I have two collections of dates and I want to figure out what dates they have in common. This is not giving me what I want (I don't know what it is giving me). What is the best way to do this?

Hi, I don't understand the following. When I create a small artificial set of date information in class POSIXct, I can calculate the mean and the median: a = as.POSIXct(Sys.time()) a = a + 60*0:10; a [1] "2009-03-10 11:30:16 EDT" "2009-03-10 11:31:16 EDT" "2009-03-10 11:32:16 EDT" [4] "2009-03-10 11:33:16 EDT" "2009-03-10 11:34:16

When I do the date +%Z I get the timezone. Which currently is EDT. I am sending information to another system, that says EDT is not a valid timezone. I have no way to modify the other system. My question is - is there a way to get the non-day-lite savings time zone ? For example EST is valid - EDT is not. Just curious if there is an easy way already present to get a standard time zone. Thanks,

Newbie here~ I've spent a ton of time on this, but have to admit I am stuck. I've tried various combinations of strptime and the package CHRON, but still can't get there. My simple task is that I want to plot salinity (S1 or S2) on y-axis and time on x-axis, but I want to use a lay-understandable representation of time (not Julian). If I use the following command, I can make a

When displaying a date field using a text_field object, is it possible to specify how the date will be formatted? <%= text_field ''item'', ''created_at'', {:class=>"text-input", :size=>18, :disabled=> true} produces 2006-07-07 12:00:00 I would like to reformat it to something like 07/07/2006 12:00pm -- Posted via

Hi I have many excel files were the Date field was not declared as date, so the dates look like this: 1/2/1978 I know that the format is day/month/year How can I make R change this to Date format? If I use strftime, I get wrong dates: dataset=c("1/2/1978") strftime(dataset,"%d/%m/%Y") "19/02/0001" Thanks in advance.

Dear R users, I am struggling a bit with the converting dates to full POSIX timestamps, in particular, I would like to somehow force the timezone to be local, i.e. the output of as.POSIXct(as.Date("2008-07-01")) should always be equal to "2008-07-01 00:00:00", is that achievable ? I tried to set the origin and the timezone, neither of which seems to make a difference. On my Mac

Hi, I would be very grateful for some advice. I have read the help pages for Date, strptime, etc. All examples seem to use some version of day month year as date format. However I have Weekly composite data so ONLY want to input the dates as Week.Year (eg 35.2011). strptime seems to show this is possible using %W for week (UK convention) and %Y for year. My data is in a df called chlorophyll and

Hi all, My mongrel server (1.0.3), with a very low usage, is taking more than 10% of cpu usage all the time (no background tasks were defined by me). This is very annoying and it is preventing me from being able to thing about good cluster configuration. Any idea on why this is happening? cheers and regards, Danilo -------------- next part -------------- An HTML attachment was scrubbed... URL:

I''m trying to create a basic web page where people can register. Before they are approved they are emailed a link where that they must click in order to verify their info is correct (or at least their email).

I have a working dialplan for our phone system with Mon-Fri, business hours identification, etc. But what I'm lacking right now is support for company holiday dates. What I'd like to do is to create a database of these dates and just update them as new years rollover. I suspect others have done this sort of thing with Asterisk before, but I've not found any resources so far.
