Interactive HTML widget for a model's factors and dummy coding

as_html_factor_views() renders a four-tab interactive widget that walks a reader through the categorical structure of a fit: the coding scheme (levels, reference, indicator columns), the per-group means, the pairwise comparisons, and the interactions. It is the web-facing companion to explain_factors().

Estimates are drawn in the Confidence-Eye grammar – a pale compatibility region with a darker interval outline and a hollow point estimate; the language is confidence/compatibility, never posterior. Tabs 2-4 need emmeans; without it they show a short note.

Usage

as_html_factor_views(x, id = "symfv", standalone = FALSE, file = NULL, ...)

Arguments

x

A symbolized_model (output of symbolize()).

id

Character id stem for the widget's element ids. Default "symfv".

standalone

Logical; if TRUE, wrap the fragment in a self-contained HTML page (with a MathJax bootstrap) suitable for opening directly in a browser. Default FALSE (an embeddable fragment).

file

Optional path; if given, the HTML is written there and returned invisibly instead of printed.

...

Reserved for future use.

Value

A character vector (HTML), invisibly.

Examples

d <- transform(mtcars, gear = factor(gear))
sym <- symbolize(lm(mpg ~ gear, data = d))
# write the interactive widget to a self-contained HTML file
html <- as_html_factor_views(sym, standalone = TRUE,
                             file = tempfile(fileext = ".html"))
