Format ANOVA statistics

Source: R/format_stats_aov.R
format_stats.aov.Rd

This method formats analysis of variance (ANOVA) statistics from the class aov. The default output is APA formatted, but this function allows control over numbers of digits, leading zeros, italics, degrees of freedom, and output format of Markdown or LaTeX.

Usage

# S3 method for class 'aov'
format_stats(
  x,
  term,
  digits = 1,
  pdigits = 3,
  pzero = FALSE,
  italics = TRUE,
  dfs = "par",
  type = "md",
  ...
)

Arguments

x

An aov object from stats::aov().

term

Character string for row name of term to extract statistics for. This must be the exact string returned in the summary() output from the aov object.

digits

Number of digits after the decimal for means, confidence intervals, and test statistics.

pdigits

Number of digits after the decimal for p-values, ranging between 1-5 (also controls cutoff for small p-values).

pzero

Logical value (default = FALSE) for whether to include leading zero for p-values.

italics

Logical value (default = TRUE) for whether p label should be italicized.

dfs

Formatting for degrees of freedom ("par" = parenthetical, "sub" = subscript, "none" = do not print degrees of freedom).

type

Type of formatting ("md" = markdown, "latex" = LaTeX).

...

Additional arguments passed to methods.

Value

A character string of statistical information formatted in Markdown or LaTeX.

Examples

test_aov <- aov(mpg ~ cyl * hp, data = mtcars)

# Format ANOVA
format_stats(test_aov, term = "cyl")
#> [1] "_F_(1, 28) = 92.5, _p_ < .001"

# Remove italics and make degrees of freedom subscripts
format_stats(test_aov, term = "cyl", italics = FALSE, dfs = "sub")
#> [1] "F~1,28~ = 92.5, p < .001"

# Change digits and add leading zero to p-value
format_stats(test_aov, term = "hp", digits = 3, pdigits = 4, pzero = TRUE)
#> [1] "_F_(1, 28) = 1.850, _p_ = 0.1846"

# Format for LaTeX
format_stats(test_aov, term = "hp", type = "latex")
#> [1] "$F$(1, 28) = 1.9, $p$ = .185"
