Standardize column names from data frames, in particular objects returned from model_parameters(), so column names are consistent and the same for any model object.

standardize_names(data, ...)

# S3 method for parameters_model
  style = c("easystats", "broom"),
  ignore_estimate = FALSE,



A data frame. In particular, objects from easystats package functions like model_parameters() or effectsize() are accepted, but also data frames returned by broom::tidy() are valid objects.


Currently not used.


Standardization can either be based on the naming conventions from the easystats-project, or on broom's naming scheme.


Logical, if TRUE, column names like "mean" or "median" will not be converted to "Coefficient" resp. "estimate".


A data frame, with standardized column names.


This method is in particular useful for package developers or users who use, e.g., model_parameters() in their own code or functions to retrieve model parameters for further processing. As model_parameters() returns a data frame with varying column names (depending on the input), accessing the required information is probably not quite straightforward. In such cases, standardize_names() can be used to get consistent, i.e. always the same column names, no matter what kind of model was used in model_parameters().

For style = "broom", column names are renamed to match broom's naming scheme, i.e. Parameter is renamed to term, Coefficient becomes estimate and so on.

For style = "easystats", when data is an object from broom::tidy(), column names are converted from "broom"-style into "easystats"-style.
