transformConstraints
Description
transformConstraints takes a list of matrices with constraints and transforms all the non-zero values to the value desired. The purpose of this function is to make easy the transformation of initial constraints to a fixed-constraint list to be provided to a mixed model fitted with the mmer function.
Usage
transformConstraints(list0,value=1)
Arguments
list0
a list of matrices with constraints according to the rules specified in the vsr function (0: not to be estimated, 1: positive, 2:unconstrained, 3:fixed).
value
value to be used to replace all the non-zero values in the constraint matrices.
Value
- $res
a list with the modified constraint matrices.
