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 form = “regressor-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
