Hi, how it's possible to extract the year and the number of days from Julian date. i'm little confused about the last two functions and ?years . EDATE comes from sqlQuery with as.is=T EDATE <- as.POSIXlt(datvears$ENROLLDAY) Many thanks, Christian > EDATE[1:5] [1] "2000-06-30 11:25:01" "2000-06-30 11:39:55" "2000-06-30 12:11:11" [4] "2000-06-30 12:13:32" "2000-06-30 12:50:12" > weekd...

...y local zone) and is incorrectly adding four hours to convert to what it thinks is UTC. Either my understanding of how this is supposed to work is wrong, or something needs to be fixed. I created a test table in a SQL Server database with one row. The table is called events and contains an "edate" column. The value is "2009-03-30 12:00", and is a UTC time. The output from script/console is below. (results are identical to using a browser) What else do I need to do to convince rails to leave the time value alone, since it *is* a UTC value? I can get the correct value by e...

Hi, I was wondering if anyone could point me to the excel look alike "Edate" and "eomonth" functions in R. I have found the "timeLastDayInMonth" and "timeFirstDayInMonth" in the "timeDate" package. However, I am looking for a bit more flexibility. I would like to be able to obtain dates and EOM dates "n" months prior...

...mber of days is a multiple of 7. However, the number of weekend days in the tail is a little harder. It depends on both the start date of the tail and the number of days in the tail. Any suggestions for a more elegant solution would be helpful. Thanks, Whit Armstrong bdays <- function(sdate,edate) { sdate <- as.POSIXlt(sdate) edate <- as.POSIXlt(edate) length <- as.integer(difftime(edate,sdate)) weeks <- floor(length/7) tail <- length%%7 # true no matter what day of the week the start date is weekend.days <- weeks*2 weekend.days <- weekend.days + # number o...

Hello, everyone I wonder if R has something similar to Excel function EDATE(start_date; months) which returns a serial number of the date that is the indicated number of months before of after the start date. Example (the second column EDATE(first_column; -6)): 01.01.1999 01.07.1998 02.02.1999 02.08.1998 06.03.1999 06.09.1998 I am working with a zoo object where the row...

Hi, I would like to check which rows of 'types.prev' matrix pop up in 'types', following R in-built procedure. I tried 'match' function but it works in case of the one dimensional vectors.

Hi, I am looking for some help concerning the npudens function in the np package. I am trying to find a kernel density function of a multivariate dataset and the density evaluated at each of the 176 points. I have 2 continuous and 3 ordered discrete variables. My sample size is 176. So edata is a 176x(2+3) data frame, while tdat is a 1x(2+3) vector. bw_cx[i,] is a 1x (2+3) vector representing the bandwidths h for each variable, which were calculated using the npcdensbw function. (no this is not a mistake, I deliberately use the conditional one) For this I use the below function in...

...er) to either "up" or "down" when the table header link is clicked. Right now, my working code (in a partial) looks something like this - <% if params[:v_order] == ''down'' %> <%= link_to "e_date", :action =>"list_by_edate", :v_order => "up" %> <% else %> <%= link_to "e_date", :action =>"list_by_edate", :v_order => "down" %> <% end %> the controller has the correct code for sorting either by ''edate'...

I read through the import/export manual a few times and did not see this mentioned and checked the archives as well. I am dealing with data sheets generated by Eprime (a software package for generating experimental psychology paradigms) that output subject responses in a proprietary Edat file format. All individual subject response spread sheets can be merged to form one long file of all subjects. As an example, if an experiment has 240 responses per subject (120 for each condition, say), each subject will generate a spreadsheet with 240 rows. After merging 10 subjects then, a m...

...out 700 total points), and then predict R1 for a new set of data for which I have all the predictors. Simple, no? I understand how to calculate bandwidths, and I have a kind of bastardized way of getting the conditional distribution, i.e., f(R1|P1=0.8,P2=0.2,P3=2) using fitted(npudens(bw=bw,edat=newdata)) evaluating over a vector of R1. I have then been using this "density" to get a maximum likelihood estimator of R1- I have no idea if that is really valid, and if anyone wants to yell at me go ahead, I want to do this the correct way and I'm sure I'm making it harder...
