coef.glmNA {Envisage} | R Documentation |
coef
is a generic function which extracts model
coefficients from objects returned by modeling
functions. coefficients
is an alias for it. This extends
the S3 method coef
to objects of class
glmNA
for package Envisage.
## S3 method for class 'glmNA': coef(object, ...)

A fitted model object of class
glmNA . |

The Envisage package contains methods allowing the use of linear models (LMs) for analysing significantly changing genes in experiments with a variety of sources of variation, be they experimentally controlled variables such as drug treatment or time, or non-controlled sources of confounding variation such as phenotypic or environmental differences. This allows all sources of variation to be considered when analysing for significant differential expression, ensuring resulting genes are biologically relevent to the experimental question.
The function coef.glmNA
extends the method
coef
to the S4 class
glmNA
for package
Envisage. This is an extension of classes glm
and
lm
and deals appropriately with the model output for genes that
produce NA calls in the modelling procedure. This allows use of the
function Anova
for calculating significance for
each gene.
alias.glmNA
is an internal function and is not
designed to be accessed by users.
