Description Usage Arguments Value Author(s) Examples

It converts a list of symmetric matrices into a stacked matrix. Dimensions of the symmetric matrices have to be the same. It tries to preserve the dimension names if possible. Dimension names will be created if there are no dimension names in the first symmetric matrix.

list2matrix(x, diag = FALSE)

`x` |
A list of |

`diag` |
Logical. If it is |

A *k* x *p** stacked matrix where *p*
= p(p-1)/2* for `diag`

=`FALSE`

or *p* = p(p+1)/2* for `diag`

=`TRUE`
