merModList models are on the list of supported models, but give errors in model_summary and other functions #1199
Description
Hello, I am trying to use model_summary() to extract information from a merModList class object created by the merTools package. merModList models are listed in supported_models(), but when I try using functions from the parameters package, I get error messages.
Some functions like model_summary() give the following error message:
Fehler: Sorry,
model_parameters()failed with the following error (possible classmerModListnot supported):
formales Argument "component" passt zu mehreren gegebenen Argumenten`
Other functions like standardize_names() just say:
Objects of class
merModListare currently not supported.
I would be very grateful for help on making merModList models work with this package. Thanks!
Example:
library(merTools) library(parameters) # example from the merTools::lmerModList help file: sim_list <- replicate(n = 10, expr = sleepstudy[sample(row.names(sleepstudy), 180),], simplify=FALSE) fml <- "Reaction ~ Days + (Days | Subject)" mod <- lmerModList(fml, data = sim_list) summary(mod) # works any(supported_models() == "merModList") # works standardize_names(mod) # doesn't work model_parameters(mod) # doesn't work SessionInfo:
