This function is Deprecated and will be removed in a future version. The pin
function works with an asreml-R version 3 model object. Since ASReml has
updated to version 4, they have changed their model output. ASReml has also
provided their own vpredict function that does (for asreml v4 model
objects) what pin did for asreml v3 model objects.
pin(object, transform)A data.frame with row names corresponding to the operator on
the left hand side of the transform formula and the entries
corresponding to the Estimate and approximate SE of the
linear transformation.
A list with at least the following elements: gammas,
gammas.type, and ai from a REML mixed model
A formula specifying the linear transformation of variance components to conduct

This function is similar to the pin calculations performed by the standalone ASReml. This function, written by Ian White, applies the delta method for the estimation of approximate standard errors on linear functions of variance components from a REML mixed model
Object is intended to be an asreml-R model output.
The formula can use V1,..., Vn to specify any one of the n
variance components. These should be in the same order as they are in the
object (e.g., see the row order of summary(object)$varcomp for
asreml-R models.
