Format correlation statistics

Source: R/format_stats_easycorrelation.R
format_stats.easycorrelation.Rd

This functions formats correlation statistics generated from the {correlation} package. This detects whether the object is from a Pearson, Spearman, or Kendall correlation and reports the appropriate correlation label (r, \(\tau\), \(\rho\)). The default output is APA formatted, but numbers of digits, leading zeros, the presence of confidence intervals, and italics are all customizable.

Usage

# S3 method for class 'easycorrelation'
format_stats(
  x,
  digits = 2,
  pdigits = 3,
  pzero = FALSE,
  full = TRUE,
  italics = TRUE,
  type = "md",
  ...
)

Arguments

x

An htest object from cor.test(), t.test(), or wilcox.test().

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.

full

Logical value (default = TRUE) for whether to include means and confidence intervals or just test statistic and p-value.

italics

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

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

# Prepare statistical objects
test_corr <- correlation::correlation(mtcars, select = "mpg", select2 = "disp")
test_corr2 <- correlation::correlation(mtcars, select = "mpg", select2 = "disp", method = "kendall")

# Format correlation
format_stats(test_corr)
#> [1] "_r_ = -.85, 95% CI [-0.92, -0.71], _p_ < .001"

# Remove confidence intervals and italics
format_stats(test_corr, full = FALSE, italics = FALSE)
#> [1] "r = -.85, p < .001"

# Change digits and add leading zero to p-value
format_stats(test_corr, digits = 3, pdigits = 4, pzero = TRUE)
#> [1] "_r_ = -0.848, 95% CI [-0.923, -0.708], _p_ < 1e-04"

# Format Kendall's tau for LaTeX
format_stats(test_corr2, type = "latex")
#> [1] "$\\rho$ = -.77, $p$ < .001"
