tbind: Bind Time Series

In tframe: Time Frame Coding Kernel

Description

Bind together (in non-time dimension) two time series objects.

Usage

    tbind(x, ..., pad.start=TRUE, pad.end=TRUE, warn=TRUE)
    ## Default S3 method:
tbind(x, ..., pad.start=TRUE, pad.end=TRUE, warn=TRUE)
    ## S3 method for class 'ts'
tbind(x, ..., pad.start=TRUE, pad.end=TRUE, warn=TRUE)
    

Arguments

x	A time series object.
...	Time series objects.
pad.start	Logical indicating if the start should be truncated or padded with NAs to align time.
pad.end	Logical indicating if the end should be truncated or padded with NAs to align time.
warn	Logical indicating if warnings should be issued.

Details

Bind data as in cbind (or formerly tsmatrix) and align time dimension. The default action pads series with NA to time union. If pad.start and/or pad.end is FALSE and the intersection is empty then NULL is returned and a warning is issued if warn=TRUE.

Value

A time series object

Examples

tbind(    ts(matrix(rnorm(24),24,1), start=c(1986,1), frequency=4),
    ts(matrix(rnorm(6),  6,1), start=c(1986,1), frequency=4))
