bdsmatrix.reconcile {bdsmatrix} | R Documentation |

## Ensure alignment of two bdsmatrix objects

### Description

This function is used by coxme. When a random effect is expressed as a sum of variance terms (matrices), it is important that all of them have the same row/column order and the same block structure. This does so, while retaining as much sparsity in the result as possible.

### Usage

```
bdsmatrix.reconcile(varlist, group)
```

### Arguments

`varlist` |
a list, each element of which is a matrix or bdsmatrix object |

`group` |
a vector of dimnames, the target match for matrice's dimnames |

### Value

a varlist, whose individual elements may have had row/column rearrangment.
