Readers, For a 12 hour time stamp: > testtime<-("2013-01-01 01:00:01 PM") > testtime [1] "2013-01-01 01:00:01 PM" > testtime24hour<-strftime(testtime,'%H:%M:%S') > testtime24hour [1] "01:00:01" how to convert to 24 hour format so that the object 'testtime24hour' is: '13:00:01' Thanks. -- r2151

Dear all, I have a time series of data that I would like to represent in a plot. But I am facing some problems to do it because the time is represented in "hours", it can start in one day and end in another day, and it is not regularly spaced. My problem is that when I plot my data, my X-axis always starts from the lower values of my time data. For example, I would like to plot data

I have a basic model class TestTime with no customization. class TestTime < ActiveRecord::Base end I would like to pass the following SQL fragment as part of an AR save call to TestTime objects. How and where would I do this in the model? "set c_time=current_time" (current_time is an SQL method, not a variable). -- Posted via http://www.ruby-forum.com/.

All, I am having trouble with a "read.table()" function that is inside of another function. But if I call the function by itself, it works fine. Moreover, if I run the script on a Mac OS X (with the default Mac OS X version of R installed, rev 2.8), it works fine. But it does not work if I run it on windows vista (also default Windows version of R, rev. 2.8). Again, both

Hello r-help, I'm trying to split a character vector of dates of the form "dd-mmm-yy" into component days, months and years. But > library(chron) > testdate<-as.POSIXlt(strptime("17-Sep-98","%d-%b-%y")) > testdate [1] "1998-09-17" > months(testdate) [1] "September" # which is fine, but for days and years I get >

While playing with DB function in Dialplan, I have added some garbage in AstDB. These are some family names with space in them. See this, demo*CLI> database show /18-05-2011 00:00:0052011175221575/TESTDATE : 2011-05-14 21:33:46 /18-05-2011 00:00:0052011175221575/TEST1 : 410 /18-05-2011 00:00:0052011175221575/TEST2 : 155 /18-05-2011 00:00:0052011182614252/TEST3 :

With dates I get different results with 2.2.1 and 2.3.1. From my somewhat naive point point of view, the 2.2.1 behaviour seems more sensible. Running the code below in 2.2.1: V1 2006-08-01 2006-08-01 1 1 With 2.3.1 I get: V1 1154354400 1154440800 1 1 # testdate.R t <- read.csv2('testdate.csv', header=FALSE) t$V1 <- as.POSIXct(t$V1)

Hi, I know this can be done in Stata (which is quite messy) but I wanted to know if it can be done in R. So lets say I have a merged data set (I used the merge function by date for the attached two files), where all the missing values are filled with NAs (which is what the all.x=TRUE does). Is there any way to replace those NAs with the value of the latest row that contains a value? For

Hi, I've completely forgotten how to do R, and it seems I can't even load simple files correctly. I have two tab deliminated text files (attached, these were test files of the larger data files I'm trying to work with) that I am trying to load into R so that I can merge them. They were originally excel files but I used "saved as" to reformat to text. I don't know if

This past holiday weekend has resulted in some real groaners when it comes to bugs in our dialplan, making obvious the need for some changes in our procedures. First, our hours of operation for Christmas Eve, Christmas, Boxing Day and New Year's Eve had changed with little to no notice. Okay, fine, whatever, I fix. Our Christmas Eve hours (made worse by being Monday this year) dialplan

Hi, When I was testing an IVR, I realized I miss a function I would call GotoIfTimeWithOffset. Today, this IVR is using function AEL GotoIfTime in several places. The problem is if it's 11pm at the moment I'm testing this IVR, I can't nicely test the 9am or 2pm branch. GotoIfTimeWithOffset would get 2 incoming arguments : - the first is a time range (just like GotoIfTime), - the
