In MassSpecWavelet: Mass spectrum processing by wavelet-based algorithms

Description

Extend the length of a signal or matrix by row

Usage

extendLength(x, addLength = NULL, method = c("reflection", "open", "circular"), direction = c("right", "left", "both"))

Arguments

x	a vector or matrix with column with each column as a signal
addLength	the length to be extended
method	three methods available, c("reflection", "open", "circular"). By default, it is "reflection".
direction	three options available: c("right", "left", "both")

Value
