Almer: Linear mixed model with correlated random effects structure

In evolvability: Calculation of Evolvability Parameters

Description

Almer fits a univariate linear mixed model incorporating a correlated random effects structure. Can be used to fit phylogenetic mixed models and animal models. The function is based on the lme4 package and is very similar to lmer, apart from the A argument.

Usage

Almer(
  formula,
  data = NULL,
  A = list(),
  REML = TRUE,
  control = lme4::lmerControl(check.nobs.vs.nlev = "ignore", check.nobs.vs.rankZ =
    "ignore", check.nobs.vs.nRE = "ignore"),
  start = NULL,
  verbose = 0L,
  weights = NULL,
  na.action = "na.omit",
  offset = NULL,
  contrasts = NULL,
  devFunOnly = FALSE,
  ...
)

Arguments

formula	as in lmer.
data	as in lmer.
A	an optional named list of sparse matrices. The names must correspond to the names of the random effects in the formula argument. All levels of the random effect should appear as row and column names for the matrices.
REML	as in lmer.
control	as in lmer.
start	as in lmer.
verbose	as in lmer.
weights	as in lmer.
na.action	as in lmer.
offset	as in lmer.
contrasts	as in lmer.
devFunOnly	as in lmer.
...	as in lmer.

Value

Almer an object of class merMod.
