matchColumns: Match number of columns

In soundgen: Sound Synthesis and Acoustic Analysis

Match number of columns

Description

Internal soundgen function

Usage

matchColumns(
  matrix_short,
  nCol,
  padWith = 0,
  padDir = "central",
  interpol = c("approx", "spline")[1]
)

Arguments

matrix_short	input matrix
nCol	the required number of columns
padWith	the value to pad with, normally 0 or NA
padDir	specifies the affected side. For padding, it is the side on which new elements will be added. For trimming, this is the side that will be trimmed. Defaults to 'central'

Details

Adds columns of new values (eg zeros or NAs) to a matrix, so that the new number of columns = len

Examples

a = matrix(1:9, nrow = 3)
soundgen:::matchColumns(a, nCol = 6, padWith = NA, padDir = 'central')
soundgen:::matchColumns(a, nCol = 6, padWith = 0, padDir = 'central')
soundgen:::matchColumns(a, nCol = 6, padWith = NA, padDir = 'left')
soundgen:::matchColumns(a, nCol = 6, padWith = 'a', padDir = 'right')
soundgen:::matchColumns(a, nCol = 2)
