fixm: fixed indication matrix
In sommer: Solving Mixed Model Equations in R
fixm R Documentation
fixed indication matrix
Description
fixm creates a square matrix with 3's in the diagnals and off-diagonals to quickly specify a fixed constraint in the Gtc argument of the vsr function.
Usage
fixm(x, reps=NULL)
Arguments
x
integer specifying the number of traits to be fitted for a given random effect.
reps
integer specifying the number of times the matrix should be repeated in a list format to provide easily the constraints in complex models that use the ds(), us() or cs() structures.
Value
- $res
a matrix or a list of matrices with the constraints to be provided in the Gtc argument of the vsr function.
