<code>lm</code>, <code>mer</code>, <code>glmmadmb</code>, <code>nls</code>, <code>survreg</code> or <code>least.rect</code> model.

model

logical. If <code>TRUE</code> a Shapiro-Wilk's test is performed on residuals.

shapiro

Plot residuals of a model against fitted values and a QQplot of these residuals. Optionally, a Shapiro-Wilk's test can be performed on residuals. The function deals with <code>lm</code> (including <code>glm</code> and <code>glm.nb</code>), <code>mer</code>, <code>glmmadmb</code>, <code>nls</code>, <code>survreg</code> and <code>least.rect</code> models. Quantile residuals (function <code>qresiduals()</code>,package statmod) are used for <code>glm.nb</code> models and for <code>glm</code> models with a poisson, quasipoisson, binomial or quasibinomial family.

This package contains diverse more or less complicated
        functions, written to simplify beginners' (but not only) life:
        simplifications of existing functions, basic but not
        implemented tests, easy-to-use tools... All functions are
        presented in the French book 'Aide-memoire de statistique
        appliquee a la biologie', written by the same author and
        available on CRAN.
