This is the unexpected behavior:

x <- .xts(, 1:10)
x[endpoints(x, 'seconds', 3), which.i=TRUE]
[,1]
1969-12-31 18:00:02 NA
1969-12-31 18:00:05 NA
1969-12-31 18:00:08 NA
1969-12-31 18:00:10 NA

I expected it to give the same result as an object that has a column:

x <- .xts(rep(42, 10), 1:10)
x[endpoints(x, 'seconds', 3), which.i=TRUE]
[1] 2 5 8 10

packageVersion('xts')
[1] ‘0.9.3.2’

Has there been a regression with this bug? I'm getting the previous unexpected behavior with xts version 0.9-7.

There may have been, but there's no issue with the current development version.

R> x <- .xts(, 1:10)
R> x[endpoints(x, 'seconds', 3), which.i=TRUE]
[1]  2  5  8 10
R> packageVersion('xts')
[1] ‘0.10.0’

Installed the current dev version via devtools, works great, thanks!
