The functions or variables listed here are no longer part of Matrix as they are no longer needed.
## Defunct in 1.3-3
rBind(..., deparse.level = 1)
cBind(..., deparse.level = 1)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 R 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.
