Print a featR result

Prints the method, how many features were kept, and their names.

Usage

# S3 method for class 'fs_result'
print(x, n = 10L, ...)

Arguments

x

An fs_result object.

n

Maximum number of selected names to list. Default 10.

...

Unused, for consistency with the generic.

Value

x, invisibly. Called for the printed output.

Details

The output has at most five lines:

1. A <fs_result> header naming the method, followed by the task in parentheses when one is known.

2. "Selected k of N features", or "Selected k features" when the number of candidates cannot be recovered from the result.

3. The selected names, truncated to the first n with a "... (m more)" tail. This line is left out when the selection is empty.

4. A "Model:" line giving the class of x$model, when the method fitted one.

5. A "Details:" line naming the elements of x$details.

Examples

fs_unsupervised(
  data.frame(a = c(1, 5, 2, 8), b = c(1, 1, 1, 1)),
  method = "variance", threshold = 0.5
)
#> <fs_result> unsupervised_variance
#> Selected 1 of 2 features
#>   a
