The functions or variables listed here are no longer part of Matrix as they are no longer needed.
## Defunct in 1.3-3rBind(..., deparse.level =1)cBind(..., deparse.level =1)
Details
These either are stubs reporting that they are defunct, or have been removed completely (apart from being documented here).
rBind and cBind were provided for versions older than 3.2.0 as substitutes for the base analogues rbind and cbind, which at that time were not S4-aware and so could not be used to vertically or horizontally concatenate "Matrix" objects together with traditional matrices and vectors.
