Print a loading matrix

Description

Print a loading matrix

Usage

## S3 method for class 'efa_loadings'
print(x, ...)

## S3 method for class 'efa_loadings'
format(
  x,
  cutoff = 0.3,
  digits = 3,
  max_name_length = 10,
  h2 = NULL,
  color = TRUE,
  name_style = c("truncate", "abbreviate", "full"),
  max_factor_name_length = NULL,
  max_factors_per_block = NULL,
  sort_loadings = c("none", "primary", "clustered"),
  legend = FALSE,
  ...
)

Arguments

x	a loading matrix of class efa_loadings (or the legacy LOADINGS).
...	additional arguments passed to print or format
cutoff	numeric. The value at or above which loadings are emphasized; default is .3.
digits	numeric. Passed to round. Number of digits to round the loadings to (default is 3).
max_name_length	numeric. The maximum length of the variable names to display. Everything beyond this will be cut from the right unless name_style = "abbreviate" or name_style = "full" is used. Cutting never leaves two variables sharing a row label: if it would (as for items with a long common prefix), the names are abbreviated instead, and numbered if needed.
h2	numeric. Vector of communalities to print. If named and x has row names, names are used to align communalities to rows.
color	logical. Whether to apply console styling using cli. Default is TRUE.
name_style	character. How to shorten variable names longer than max_name_length. "truncate" cuts names from the right, "abbreviate" uses base::abbreviate(), and "full" prints full names.
max_factor_name_length	numeric or NULL. Optional maximum length of factor names. If NULL, factor names are not shortened.
max_factors_per_block	numeric or NULL. Maximum number of factor columns to print per block. If NULL, the number is chosen from the console width.
sort_loadings	character. Optional row sorting. "none" preserves the input order, "primary" groups rows by the factor with the largest absolute loading, and "clustered" additionally sorts within each factor by the size of the primary loading.
legend	logical. Whether to append a short explanation of the styling. Default is FALSE for standalone loading matrices. The legend is only printed when the styling it describes is actually rendered (color = TRUE and a colour-capable console); in plain output it is omitted and this argument has no effect.

Details

The method prints a loading matrix in a compact, console-oriented table. Loadings with absolute value greater than or equal to cutoff are emphasized, smaller loadings are de-emphasized, and Heywood-relevant communality/ uniqueness values are marked when h2 is supplied. Long variable names can be truncated, abbreviated, or printed in full. If the matrix has many factor columns, the table is split into column blocks so that the output remains readable in narrower consoles.

If h2 is named and x has row names, h2 is matched to the row names of x before any optional row sorting is applied. If x has no row names, a named h2 vector is used in the supplied order.

Value

print() returns its argument x invisibly; it is cat(format(x, ...), sep = "\n") followed by a blank line for console spacing. format() returns a character vector with the table lines (styled to the active console theme; plain when colours are disabled).

Examples

EFAtools_PAF <- efa_fit(test_models$baseline$cormat, n_factors = 3, N = 500,
                        estimator = "PAF", rotation = "promax")
EFAtools_PAF

# format() returns the same lines as a character vector:
writeLines(format(EFAtools_PAF$rot_loadings))
