mergeTraces

Merge multiple traces into a single trace

Description

The mergeTraces method of Stream objects returns a new Stream where all Traces have been merged into a single Trace. Gaps between traces are replaced with values determined by the fillMethod parameter.

Usage

mergeTraces(x, fillMethod)

Arguments

`x`	`Stream` object
`fillMethod`	method to use when filling gaps between `Traces` (default=`"fillNA"`)

Details

Available values for fillMethod include:

fillNA – gaps are filled with NA (R's missing value flag)
fillZero – gaps are filled with 0.0

Value

A new Stream object containing a single Trace is returned.
