In asremlPlus: Augments 'ASReml-R' in Fitting Mixed Models and Packages Generally in Exploring Prediction Differences

Gets the p-value for a test recorded in the test.summary data.frame of an asrtests.object

Description

Matches the label in the term column of the test.summary data.frame in the supplied asrtests.object and extracts its p-value. It only matches the last occurrence of label.

Usage

## S3 method for class 'asrtests'
getTestPvalue(asrtests.obj, label, ...)

Arguments

asrtests.obj	An asrtests.object containing the components (i) asreml.obj, (ii) wald.tab, and (iii) test.summary.
label	A character specifying the label of the test for which the p-value is required. If testranfix.asrtests was used for the test of interest, then the label will be the value of the term argument supplied to testranfix.asrtests. Other arguments will be relevant for other test functions.
...	provision for passing arguments to functions called internally - not used at present.

Value

An numeric containing the p-value. It can be NA, for example when a p-value could not be calculated.
