addVectors | R Documentation |

Adds two partly overlapping vectors, such as two waveforms, to produce a longer vector. The location at which vector 2 is pasted is defined by insertionPoint. Algorithm: both vectors are padded with zeros to match in length and then added. All NA's are converted to 0.

addVectors(v1, v2, insertionPoint = 1, normalize = TRUE)

`v1, v2` |
numeric vectors |

`insertionPoint` |
the index of element in vector 1 at which vector 2 will be inserted (any integer, can also be negative) |

`normalize` |
if TRUE, the output is normalized to range from -1 to +1 |

`soundgen`

v1 = 1:6 v2 = rep(100, 3) addVectors(v1, v2, insertionPoint = 5, normalize = FALSE) addVectors(v1, v2, insertionPoint = -4, normalize = FALSE) # note the asymmetry: insertionPoint refers to the first arg addVectors(v2, v1, insertionPoint = -4, normalize = FALSE) v3 = rep(100, 15) addVectors(v1, v3, insertionPoint = -4, normalize = FALSE) addVectors(v2, v3, insertionPoint = 7, normalize = FALSE)
