Build a linear model for ART data with response aligned or aligned and ranked by the specified term from the model.
artlm(
m,
term,
response = c("art", "aligned"),
factor.contrasts = "contr.sum",
...
)An object of class lm if formula(m) does not
contain grouping or error terms, an object of class merMod
(i.e. a model fit by lmer) if it contains grouping terms, or
an object of class aovlist (i.e. a model fit by aov) if
it contains error terms.
An object of class art.
A character vector indicating the effect term
in the transformed data in m to use as the aligned or art response.
Which response to use: the aligned response
("aligned") or the aligned and ranked ("art") response.
The name of the contrast-generating function to be
applied by default to fixed effect factors. Sets the the first element of
options("contrasts") for the duration of this function. The
default is to use "contr.sum", i.e. sum-to-zero contrasts, which is
appropriate for Type III ANOVAs (the default ANOVA type for
anova.art).
Matthew Kay
This function is used primarily for post-hoc tests. To run an ANOVA, it does
not need to be called directly; instead, use anova.art, which
calls this function as needed.
See art for an example. See also
anova.art, which makes use of this function.
