Description
mef.asreml calculates regressor (marker) effects using the original regressor scores and an asreml fit using the known subject relationship matrix.
Usage
## S3 method for class 'asreml' meff(object, effects = ~NULL, mef = list(), se = FALSE, evaluate = TRUE, ...)
Arguments
object |
An asreml object. |
effects |
A one sided formula giving the terms in the model (separated by “+”) for which marker effects are to be calculated. If ~NULL, the default, the term associated with the first variance matrix in the mef list will be used. |
mef |
A list associating a known relationship matrix (rm) used in the model with a matrix of regressor scores, with components in the formregressor-scores“. |
se |
If TRUE, calculate the standard errors of the effects; default FALSE. |
evaluate |
If TRUE (the default), evaluate the effects by a call to update.asreml, otherwise return the unevaluated call. |
... |
Additional arguments to asreml. |
Value
An asreml object with a component mef, a list with length(mef) components containing the matrices of regressor effects and (optional) standard errors
