modelsummary (version 2.3.0)

datasummary_correlation_format: Format the content of a correlation table

Description

Mostly for internal use, but can be useful when users supply a function to the method argument of datasummary_correlation.

Usage

datasummary_correlation_format(
  x,
  fmt,
  leading_zero = FALSE,
  diagonal = NULL,
  upper_triangle = NULL,
  stars = FALSE
)

Arguments

x

square numeric matrix

fmt

how to format numeric values: integer, user-supplied function, or modelsummary function.

• Integer: Number of decimal digits

• User-supplied functions:

  • Any function which accepts a numeric vector and returns a character vector of the same length.

• modelsummary functions:

  • fmt = fmt_significant(2): Two significant digits (at the term-level)

  • fmt = fmt_sprintf("%.3f"): See ?sprintf

  • fmt = fmt_identity(): unformatted raw values

leading_zero

boolean. If FALSE, leading zeros are removed

diagonal

character or NULL. If character, all elements of the diagonal are replaced by the same character (e.g., "1").

upper_triangle

character or NULL. If character, all elements of the upper triangle are replaced by the same character (e.g., "" or ".").

stars

to indicate statistical significance

• FALSE (default): no significance stars.

• TRUE: c("+" = .1, "*" = .05, "**" = .01, "***" = 0.001)

• Named numeric vector for custom stars such as c('*' = .1, '+' = .05)

• Note: a legend will not be inserted at the bottom of the table when the estimate or statistic arguments use "glue strings" with {stars}.

Examples

library(modelsummary)

dat <- mtcars[, c("mpg", "hp", "disp")]

cor_fun <- function(x) {
  out <- cor(x, method = "kendall")
  datasummary_correlation_format(
    out,
    fmt = 2,
    upper_triangle = "x",
    diagonal = ".")
}

datasummary_correlation(dat, method = cor_fun)
