Automatic reporting of R objects

Create reports of different objects. See the documentation for your object's class:

Usage

report(x, ...)

Arguments

x

The R object that you want to report (see list of of supported objects above).

...

Arguments passed to or from other methods.

Value

A list-object of class report, which contains further list-objects with a short and long description of the model summary, as well as a short and long table of parameters and fit indices.

Details

• System and packages (sessionInfo)

• Dataframes and vectors

• Correlations and t-tests (htest)

• ANOVAs (aov, anova, aovlist, ...)

• Regression models (glm, lm, ...)

• Mixed models (glmer, lmer, glmmTMB, ...)

• Bayesian models (stanreg, brms...)

• Bayes factors (from bayestestR)

• Structural Equation Models (SEM) (from lavaan)

• Model comparison (from performance())

Most of the time, the object created by the report() function can be further transformed, for instance summarized (using summary()), or converted to a table (using as.data.frame()).

Organization

report_table and report_text are the two distal representations of a report, and are the two provided in report(). However, intermediate steps are accessible (depending on the object) via specific functions (e.g., report_parameters).

Output

The report() function generates a report-object that contain in itself different representations (e.g., text, tables, plots). These different representations can be accessed via several functions, such as:

• as.report_text(r): Detailed text.

• as.report_text(r, summary=TRUE): Minimal text giving the minimal information.

• as.report_table(r): Comprehensive table including most available indices.

• as.report_table(r, summary=TRUE): Minimal table.

Note that for some report objects, some of these representations might be identical.
