search for: idate

Debugging this issue: https://github.com/Rdatatable/data.table/issues/2008 We have custom class 'IDate' which inherits from 'Date' (it just forces integer storage for efficiency, hence, I). The concatenation done by rbind, however, breaks this and returns a double: library(data.table) DF = data.frame(date = as.IDate(Sys.Date())) storage.mode(rbind(DF, DF)$date) # [1] "double"...

...ger snap of clarity on the whole issue. I'll add that actually it was data.table's code at fault on the storage conversion -- note that if you use an arbitrary sub-class 'foo' with no methods defined, it'll stay integer. That's because [<- calls as.Date and then as.Date.IDate, and that method (ours) has as.numeric(); earlier I had recognized that if we commented that line, the issue was "fixed" but I still wasn't understanding the root cause. My last curiosity on this issue will be in my follow-up thread. Mike C On Mon, May 27, 2019, 10:25 PM Joshua Ulr...

...it would be good to summarize my thoughts, since I made a few hypotheses that turned out to be false. This isn't a bug in base R, in either rbind() or `[<-.Date`. To summarize the root cause: base::rbind.data.frame() calls `[<-` for each column of the data.frame, and there is no `[<-.IDate` method to ensure the replacement value is converted to integer. And, in fact, `[<-.Date` calls as.Date() and data.table::as.Date.IDate() calls as.numeric() on the IDate object. So the problem exists, and can be fixed, in data.table.

Have finally managed to come up with a fix after checking out sys.calls() from within the as.Date.IDate debugger, which shows something like: [[1]] rbind(DF, DF) [[2]] rbind(deparse.level, ...) [[3]] `[<-`(`*tmp*`, ri, value = 18042L) [[4]] `[<-.Date`(`*tmp*`, ri, value = 18042L) [[5]] as.Date(value) [[6]] as.Date.IDate(value) I'm not sure why [<- is called, I guess the implementation...

Dear Bioc and R List Users, I am having trouble analysing illumine data generated from BeadScan. I have .idat files and JPEG images. I realise that i need bead-level summary data to be able to begin quality control followed by normalization. Is there a way i can read .idat files for expression analysis or do i need to go back to BeadScan and generate .txt files/tiff files ? Appreciate any help

Hi Experts, I have a problem in Dates. I have a zoo object called 'intra'. And the class of index(intra) is ("Chron" "Dates" "Time"). I need to put the index of this zoo object into a data frame. So I used, idat<-data.frame(Datetime=as.POSIXlt(index(intra),"GMT")) But I get the values of 'idat' to be: "01joulu2006

This is an attempt to make supermin check for the existing results of an output when checking whether the appliance must be rebuilt using --if-newer. At the moment it is implemented only for the ext2 output format of the build mode. Changes from v1: - drop empty stub for the prepare mode - add patch to ignore --if-newer on modes different than build - squash patch with stub for the build mode

I'm using R 2.8.1 on Ubuntu 8.10. I'm writing partly to ask what's wrong, partly to tell other users who search that there is a work around. The General Social Survey is a long standing series of surveys provided by NORC (National Opinion Research Center). I have downloaded some years of the survey data in SPSS format (here's the site:

I have a simple query as follows: "SELECT m_id,sale_date,YEAR(sale_date),WEEK(sale_date),return_type,DATEDIFF(return_date,sale_date) AS elapsed_time FROM risk_input" I can get, and view, all the data that that query returns. The question is, sale_date is a timestamp, and I need to call split to group this data by m_id and the week in which the sale occurred. Obviously, I would
