Details

Duplicate index values are supported. When one or more input has the same index value, the duplicated index values in the result are in the same order the objects are passed to rbind(). See examples.

c() is an alias for rbind() for xts objects.

See merge.xts() for traditional merge operations.

Examples

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)
