I came across a race condition in lightdm greeter setup phase before the login screen is displayed (at boot time or after logout). I reported this also on Launchpad with more details (https://bugs.launchpad.net/lightdm/+bug/1172752), but to work on a proper fix, ideas on how to fix this would be welcome. During greeter setup "lightdm --session-child" is spawned twice. The first call to

CentOS team... as is already bug reported and marked solved... as we await the upstream repair for this. It was reported that this was happening on CentOS 5. You likely already know, but it also happens on CentOS 4. For those unaware. It seems that SquirrelMail has an issue which allows mail to be sent out from one user on the system and it uses the from address of another user on the

Hi all, I have a data set with time interval and depending on the interval I want to create 5 more variables . Sample data below obs, Start, End 1,2/1/2015, 1/1/2017 2,4/11/2010, 1/1/2011 3,1/4/2006, 5/3/2007 4,10/1/2007, 1/1/2008 5,6/1/2011, 1/1/2012 6,10/15/2004,12/1/2004 First, I want get interval between the start date and end dates (End-start). obs, Start , end, datediff

Ii is difficult to provide useful help, because you have failed to read and follow the posting guide. In particular: 1. Plain text, not HTML. 2. Use dput() or provide code to create your example. Text printouts such as that which you gave require some work to wrangle into into an example that we can test. Specifically: 3. Have you gone through any R tutorials?-- it sure doesn't look like

Thank you all for the useful suggestion. I did some of my homework. library(data.table) DFM <- read.table(header=TRUE, text='obs start end 1 2/1/2015 1/1/2017 2 4/11/2010 1/1/2011 3 1/4/2006 5/3/2007 4 10/1/2007 1/1/2008 5 6/1/2011 1/1/2012 6 10/5/2004 12/1/2004',stringsAsFactors = FALSE) DFM DFM$D =as.numeric(difftime(as.Date(DFM$end,format="%m/%d/%Y"),

I have a standard form built with rails, which a user to my site can use to submit data. Unfortunately one user just managed to submit exactly the the same data three times in a row. From the server logs it seems as though he didn''t use his back button and then resubmit everything. It looks more like he got a bit fed up waiting for the form to process and pressed the submit button three

Thank you Jeff and All, Within a given time period (say 700 days, from the start day), I am expecting measurements taken at each time interval;. In this case "0" means measurement taken, "1" not taken (stopped or opted out and " -1" don't consider that time period for that individual. This will be compared with the actual measurements taken (Observed-

Since the number of choices is small (6), how about this? Starting with Jeff's initial DFM: DFM <- structure(list(obs = 1:6, start = structure(c(16467, 14710, 13152, 13787, 15126, 12696), class = "Date"), end = structure(c(17167, 14975, 13636, 13879, 15340, 12753), class = "Date"), D = c(700, 265, 484, 92, 214, 57), bin = structure(c(6L, 3L, 5L, 1L, 3L, 1L), .Label

Hi I have the following columns with dates and results, sorted by subject and date. I'd like to compute the differences in dates and results for each patient, based on the previous row. Obviously the last entry for each subject should be a NA. Which would be the best way to accomplished that ? I guess questions like that have been already answered a thousand times, so I apologize for

Hi all, I have the following problem: I have a csv-file consisting of timestamp values (no dates), e.g.: Timestamp1;Timestamp2; 05:24:43;05:25:05; 15:47:02;15:47:22; 18:36:05;18:36:24; 15:21:24;15:22:04; I need a vector with the difference of the two timestamps, so I read the data with the read.csv-function: myObj <- read.csv("file.csv",header=TRUE,sep=";"). I have then

My last query related to this referred to a problem with not being able to store data. A suggestion was made to try to convert the data returned by fitdist into a data.frame before using rbind. That failed, but provided the key to solving the problem (which was to create a data.frame using the variables fitdist produces in the object it returns). I now have almost everything working as
