r - issues when trying to make indices unique in xts -


i have following xts object:

options("digits.secs" = 1) ex <- structure(c(na, -63l, na, na, na, na, na, 0l, na, na, na, na,  na, 1l, na, na, na, na), .dim = c(6l, 3l), .dimnames = list(null,      c("v2", "v3", "v4")), index = structure(c(1366088402.46,  1366088402.46, 1366088402.463, 1366088402.463, 1366088469.697,  1366088469.697), tzone = "", tclass = c("posixct", "posixt")), class = c("xts", "zoo"), .indexclass = c("posixct", "posixt"), tclass = c("posixct", "posixt"), .indextz = "", tzone = "") ex <- make.index.unique(ex, drop = true, fromlast = true)

however, resulting xts object doesn't have unique indices. i've tried using strptime format="...%os1", returns na values. above code intuitively doesn't make sense me because i'm using output options try , truncate dates.

i've searched how other people handling fractional timestamps, , results seem consistent above. why isn't %os1 working me, , options correct way handle this? want time index internally truncated @ specified increments, index shouldn't change every time set options("digits.secs") new.

> options("digits.secs"=3) > head(ex)                          v2 v3 v4 2013-04-16 00:00:02.460  na na na 2013-04-16 00:00:02.460 -63  0  1 2013-04-16 00:00:02.463  na na na 2013-04-16 00:00:02.463  na na na 2013-04-16 00:01:09.697  na na na 2013-04-16 00:01:09.697  na na na > ex <- align.time(ex, n = 0.1) > head(ex)                        v2 v3 v4 2013-04-16 00:00:02.5  na na na 2013-04-16 00:00:02.5 -63  0  1 2013-04-16 00:00:02.5  na na na 2013-04-16 00:00:02.5  na na na 2013-04-16 00:01:09.7  na na na 2013-04-16 00:01:09.7  na na na > ex <- make.index.unique(ex, drop = true, fromlast = true) > head(ex)                          v2     v3   v4 2013-04-16 00:00:02.5    na     na   na 2013-04-16 00:01:09.7    na     na   na 2013-04-16 00:01:09.7 -65.5  -7500 0.25 2013-04-16 00:01:13.5 -64.0  -7500 0.25 2013-04-16 00:01:15.4 -64.0 -10000 0.20 2013-04-16 00:01:24.9 -64.0 -10000 0.20

as can see data getting cut down third in length, in first few rows there repeated time index @ 00:01:09.7.

try modify format this:

strptime(sys.time(), format = "%y-%m-%d %h:%m:%s")

the 'format = "%y/%m/%d %h:%m:%s"'output na:

strptime(sys.time(), format = "%y/%m/%d %h:%m:%s")

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite...
