R: Extract model coefficients

coef.asreml {asreml}

R Documentation

Extract model coefficients

Description

Extracts model coefficients (solutions for BLUEs or BLUPs) from an asreml object.

Usage

## S3 method for class 'asreml'
coef(object, list = FALSE, pattern = ~NULL, ...)

Arguments

`object`	An `asreml` object.
`list`	If `TRUE`, the coefficients are returned in a named list whose length is the number of terms in the model (default = `FALSE`).
`pattern`	A term in the model as a one-sided formula. A regular expression is constructed from `pattern` to extract a subset of coefficients.
`...`	Additional arguments.

Value

If neither pattern nor list are set, then a list of length two with the following components:

fixed: Solutions to the mixed model equations for the fixed terms.
random: E-BLUPs for the effects in the random model.

where each component is a matrix with a dimnames attribute.

If list = TRUE, a list object where each component is a single-column matrix corresponding to a term in the model is returned. Otherwise, a single-column matrix of effects as specified by pattern.

coef(oats.vsr)
coef(oats.vsr, list = TRUE)
coef(oats.vsr, pattern = ~Blocks:Wplots)
