add_correlations: Add correlations from the correlation package in easystats

Description

Add correlations from the correlation package in easystats

Usage

add_correlations(
  .df,
  var_set,
  variables,
  focus_set = NULL,
  method = "auto",
  redundant = TRUE,
  add_matrix = TRUE
)

Value

a data.framewith three columns: type, group, and code. Type indicates the decision type, group is a decision, and the code is the actual code that will be executed. If part of a pipe, the current set of decisions will be appended as new rows.

Arguments

.df

the original data.frame(e.g., base data set). If part of set of add_* decision functions in a pipeline, the base data will be passed along as an attribute.

var_set

character string. Should be a descriptive name of the correlation matrix.

variables

the variables for which you would like to correlations. These variables will be passed to link[correlation]{correlation}. You can also use tidyselect to select variables.

focus_set

variables to focus one in a table. This produces a table where rows are each focused variables and columns are all other variables

method

a valid method of correlation supplied to link[correlation]{correlation} (e.g., 'pearson' or 'kendall'). Defaults to 'auto'. See link[correlation]{correlation} for more details.

redundant

logical, should the result include repeated correlations? Defaults to TRUE See link[correlation]{correlation} for details.

add_matrix

logical, add a traditional correlation matrix to the output. Defaults to TRUE.

    mod1 = rnorm(500),

    include1 = rbinom(500, size = 1, prob = .1),
    include2 = sample(1:3, size = 500, replace = TRUE),
    include3 = rnorm(500)
