Prints a compact summary of what a selection run kept.
Usage
# S3 method for class 'fs_result'
print(x, n = 10L, ...)Details
The output is at most five lines: a <fs_result> header naming the method,
followed by the task in parentheses when one is known; a count, either
"Selected k of N features" or, when the number of candidates cannot be
recovered, "Selected k features"; the selected names, truncated to the
first n with a "... (m more)" tail; a "Model:" line giving the class of
x$model when the method fitted one; and a "Details:" line naming the
elements of x$details. Nothing is printed for the names when the
selection is empty.
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
#> Details: mask, indices, filtered, threshold, direction, action, n_features (in $details)
