Concatenate or bind by row two or more xts objects along a time-based index.

Implemented in C, these functions bind xts objects
by row, resulting in another xts object
There may be non-unique index values in either the original series, or the resultant series.
Identical indexed series are bound in the order or the arguments passed to rbind. See examples.
All objects must have the same number of
columns, as well as be xts objects
or coercible to such.
rbind and c are aliases.
For traditional merge operations, see merge.xts and
cbind.xts.
An xts object with one row per row
for each object concatenated.
This differs from rbind.zoo in that non-unique index values are allowed, in addition to the completely different algorithms used internally.
All operations may not behave as expected on objects with non-unique indices. You have been warned.
rbind is a .Primitive function in R. As such
method dispatch occurs at the C-level, and may not be
consistent with expectations. See the details section
of the base function, and if needed call rbind.xts directly
to avoid dispatch ambiguity.

x <- xts(1:10, Sys.Date()+1:10) str(x) merge(x,x) rbind(x,x) rbind(x[1:5],x[6:10]) c(x,x) # this also works on non-unique index values x <- xts(rep(1,5), Sys.Date()+c(1,2,2,2,3)) y <- xts(rep(2,3), Sys.Date()+c(1,2,3)) # overlapping indexes are appended rbind(x,y) rbind(y,x)
