Create a rich-formatted table using the table of coefficients of the summary.nls object

This function extracts and formats the table of coefficients from a summary.nls object, similar to stats::coef(), but in flextable object.

# S3 method for class 'summary.nls'
tabularise_coef(
  data,
  header = TRUE,
  title = header,
  equation = header,
  auto.labs = TRUE,
  origdata = NULL,
  labs = NULL,
  lang = getOption("SciViews_lang", "en"),
  footer = FALSE,
  show.signif.stars = getOption("show.signif.stars", TRUE),
  ...,
  kind = "ft"
)

Arguments

data: An nls object.
header: If TRUE (by default), add a title to the table.
title: If TRUE, add a title to the table header. Default to the same value than header, except outside of a chunk where it is FALSE if a table caption is detected (tbl-cap YAML entry).
equation: Add equation of the model to the table. If TRUE, equation() is used. The equation can also be passed in the form of a character string (LaTeX).
auto.labs: If TRUE (by default), use labels (and units) automatically from data or origdata=.
origdata: The original data set this model was fitted to. By default it is NULL and no label is used (only the name of the variables).
labs: Labels to change the names of elements in the term column of the table. By default it is NULL and nothing is changed.
lang: The language to use. The default value can be set with, e.g., options(SciViews_lang = "fr") for French.
footer: If FALSE (by default), add a footer to the table.
show.signif.stars: If TRUE, add the significance stars to the table. The default is getOption("show.signif.stars")
...: Not used
kind: The kind of table to produce: "tt" for tinytable, or "ft" for flextable (default).

Value

A flextable object that you can print in different forms or rearrange with the {flextable} functions.

Examples

data("ChickWeight", package = "datasets")
chick1 <- ChickWeight[ChickWeight$Chick == 1, ]
# Adjust a logistic curve
chick1_logis <- nls(data = chick1, weight ~ SSlogis(Time, Asym, xmid, scal))
chick1_logis_sum <- summary(chick1_logis)
