Arguments

`x`	An object returned by `compare_parameters()`.
`split_components`	Logical, if `TRUE` (default), For models with multiple components (zero-inflation, smooth terms, ...), each component is printed in a separate table. If `FALSE`, model parameters are printed in a single table and a `Component` column is added to the output.
`select`	Determines which columns and and which layout columns are printed. There are three options for this argument: Selecting columns by name or index `select` can be a character vector (or numeric index) of column names that should be printed. There are two pre-defined options for selecting columns: `select = "minimal"` prints coefficients, confidence intervals and p-values, while `select = "short"` prints coefficients, standard errors and p-values. A string expression with layout pattern `select` is a string with "tokens" enclosed in braces. These tokens will be replaced by their associated columns, where the selected columns will be collapsed into one column. However, it is possible to create multiple columns as well. Following tokens are replaced by the related coefficients or statistics: `{estimate}`, `{se}`, `{ci}` (or `{ci_low}` and `{ci_high}`), `{p}` and `{stars}`. The token `{ci}` will be replaced by `⁠{ci_low}, {ci_high}⁠`. Furthermore, a `\|` separates values into new cells/columns. If `format = "html"`, a `⁠<br>⁠` inserts a line break inside a cell. See 'Examples'. A string indicating a pre-defined layout `select` can be one of the following string values, to create one of the following pre-defined column layouts: `"ci"`: Estimates and confidence intervals, no asterisks for p-values. This is equivalent to `select = "{estimate} ({ci})"`. `"se"`: Estimates and standard errors, no asterisks for p-values. This is equivalent to `select = "{estimate} ({se})"`. `"ci_p"`: Estimates, confidence intervals and asterisks for p-values. This is equivalent to `select = "{estimate}{stars} ({ci})"`. `"se_p"`: Estimates, standard errors and asterisks for p-values. This is equivalent to `select = "{estimate}{stars} ({se})"`.. `"ci_p2"`: Estimates, confidence intervals and numeric p-values, in two columns. This is equivalent to `select = "{estimate} ({ci})\|{p}"`. `"se_p2"`: Estimate, standard errors and numeric p-values, in two columns. This is equivalent to `select = "{estimate} ({se})\|{p}"`. For `model_parameters()`, glue-like syntax is still experimental in the case of more complex models (like mixed models) and may not return expected results.
`digits`, `ci_digits`, `p_digits`	Number of digits for rounding or significant figures. May also be `"signif"` to return significant figures or `"scientific"` to return scientific notation. Control the number of digits by adding the value as suffix, e.g. `digits = "scientific4"` to have scientific notation with 4 decimal places, or `digits = "signif5"` for 5 significant figures (see also `signif()`).
`ci_width`	Minimum width of the returned string for confidence intervals. If not `NULL` and width is larger than the string's length, leading whitespaces are added to the string. If `width="auto"`, width will be set to the length of the longest string.
`ci_brackets`	Logical, if `TRUE` (default), CI-values are encompassed in square brackets (else in parentheses).
`zap_small`	Logical, if `TRUE`, small values are rounded after `digits` decimal places. If `FALSE`, values with more decimal places than `digits` are printed in scientific notation.
`format`	String, indicating the output format. Can be `"markdown"` or `"html"`.
`groups`	Named list, can be used to group parameters in the printed output. List elements may either be character vectors that match the name of those parameters that belong to one group, or list elements can be row numbers of those parameter rows that should belong to one group. The names of the list elements will be used as group names, which will be inserted as "header row". A possible use case might be to emphasize focal predictors and control variables, see 'Examples'. Parameters will be re-ordered according to the order used in `groups`, while all non-matching parameters will be added to the end.
`engine`	Character string, naming the package or engine to be used for printing into HTML or markdown format. Currently supported `"gt"` (or `"default"`) to use the gt package to print to HTML and the default easystats engine to create markdown tables. If `engine = "tt"`, the tinytable package is used for printing to HTML or markdown. Not all `print()` methods support the `"tt"` engine yet. If a specific `print()` method has no `engine` argument, `insight::export_table()` is used, which uses gt for HTML printing.
`...`	Arguments passed to or from other methods.
`caption`	Table caption as string. If `NULL`, depending on the model, either a default caption or no table caption is printed. Use `caption = ""` to suppress the table caption.
`subtitle`	Table title (same as caption) and subtitle, as strings. If `NULL`, no title or subtitle is printed, unless it is stored as attributes (`table_title`, or its alias `table_caption`, and `table_subtitle`). If `x` is a list of data frames, `caption` may be a list of table captions, one for each table.
`footer`	Can either be `FALSE` or an empty string (i.e. `""`) to suppress the footer, `NULL` to print the default footer, or a string. The latter will combine the string value with the default footer.
`column_width`	Width of table columns. Can be either `NULL`, a named numeric vector, or `"fixed"`. If `NULL`, the width for each table column is adjusted to the minimum required width. If a named numeric vector, value names are matched against column names, and for each match, the specified width is used. If `"fixed"`, and table is split into multiple components, columns across all table components are adjusted to have the same width.
`font_size`	For HTML tables, the font size.
`line_padding`	For HTML tables, the distance (in pixel) between lines.
`column_labels`	Labels of columns for HTML tables. If `NULL`, automatic column names are generated. See 'Examples'.

Value

Invisibly returns the original input object.

Global Options to Customize Messages and Tables when Printing

The verbose argument can be used to display or silence messages and warnings for the different functions in the parameters package. However, some messages providing additional information can be displayed or suppressed using options():

parameters_summary: options(parameters_summary = TRUE) will override the summary argument in model_parameters() and always show the model summary for non-mixed models.
parameters_mixed_summary: options(parameters_mixed_summary = TRUE) will override the summary argument in model_parameters() for mixed models, and will then always show the model summary.
parameters_cimethod: options(parameters_cimethod = TRUE) will show the additional information about the approximation method used to calculate confidence intervals and p-values. Set to FALSE to hide this message when printing model_parameters() objects.
parameters_exponentiate: options(parameters_exponentiate = TRUE) will show the additional information on how to interpret coefficients of models with log-transformed response variables or with log-/logit-links when the exponentiate argument in model_parameters() is not TRUE. Set this option to FALSE to hide this message when printing model_parameters() objects.

There are further options that can be used to modify the default behaviour for printed outputs:

parameters_labels: options(parameters_labels = TRUE) will use variable and value labels for pretty names, if data is labelled. If no labels available, default pretty names are used.
parameters_interaction: ⁠options(parameters_interaction = <character>)⁠ will replace the interaction mark (by default, *) with the related character.
parameters_select: ⁠options(parameters_select = <value>)⁠ will set the default for the select argument. See argument's documentation for available options.
easystats_html_engine: options(easystats_html_engine = "gt") will set the default HTML engine for tables to gt, i.e. the gt package is used to create HTML tables. If set to tt, the tinytable package is used.

Examples



data(iris)
lm1 <- lm(Sepal.Length ~ Species, data = iris)
lm2 <- lm(Sepal.Length ~ Species + Petal.Length, data = iris)

# custom style
result <- compare_parameters(lm1, lm2, select = "{estimate}{stars} ({se})")
print(result)

# custom style, in HTML
result <- compare_parameters(lm1, lm2, select = "{estimate}<br>({se})|{p}")
