Dear all, I have a zoo object that has following structure:
> str(bldata) zoo [1:5219, 1:12] 91.9 91.8 91.7 91.8 91.7 ... - attr(*, "index")=Classes 'dates', 'times' atomic [1:5219] 7305 7306 7307 7308 7309 ... .. ..- attr(*, "format")= chr "m/d/y" .. ..- attr(*, "origin")= Named num [1:3] 1 1 1970 .. .. ..- attr(*, "names")= chr [1:3] "month" "day" "year" - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:12] "ED4 COMDTY" "ED12 COMDTY" "ER4 COMDTY" "ER12 COMDTY" ... I also have a vector of dates of same length as zoo object (5219): > str(bldates) chr [1:5219] "01/01/90" "01/02/90" "01/03/90" "01/04/90" "01/05/90" "01/08/90" "01/09/90" "01/10/90" "01/11/90" "01/12/90" ... I do the following: > attributes(bldata)[[2]] <- as.Date(bldates, "%m/%d/%y") and get the following: > str(bldata) 'zoo' series from 1990-01-01 to 2009-12-31 Data: num [1:5219, 1:12] 91.9 91.8 91.7 91.8 91.7 ... - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:12] "ED4 COMDTY" "ED12 COMDTY" "ER4 COMDTY" "ER12 COMDTY" ... Index: Class 'Date' num [1:5219] 7305 7306 7307 7308 7309 ... But what I really want to get is the following: >str(bldata) 'zoo' series from 01/01/90 to 12/31/09 Data: num [1:5219, 1:12] 91.9 91.8 91.7 91.8 91.7 ... - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:12] "ED4 COMDTY" "ED12 COMDTY" "ER4 COMDTY" "ER12 COMDTY" ... Index: Classes 'dates', 'times' atomic [1:5219] 7305 7306 7307 7308 7309 ... ..- attr(*, "format")= chr "m/d/y" ..- attr(*, "origin")= Named num [1:3] 1 1 1970 .. ..- attr(*, "names")= chr [1:3] "month" "day" "year" The array bldata is the same, only the last one is on a machine running RBloomberg, and then I tried to save bldata (and rownames of bldata in bldates) and transfer bldata to the other machine which is not a Bloomberg terminal, and the structure of bldata changes. What should I do in this case to adjust the structure? I guess I have to somehow change the class of Index and set attributes of "Index" and attribute "names" of attribute "origin" of attribute "Index"? Thank you for your help in advance!
