Estimate per-feature skewness and optionally flag features beyond a user-defined
skewness threshold.
Usage
feature_skewness(data, threshold = NULL, direction = "left")
Arguments
- data
matrix, a numeric matrix with samples in rows and features in columns.
- threshold
numeric, optional skewness threshold. If `NULL`, only skewness is
returned and no exclusion flag is calculated.
- direction
character, direction of skewness to flag. One of `"left"`,
`"right"`, or `"both"`.
Value
data.frame with columns `feature_id`, `skew`, and
`exclude_by_skewness` (logical; `NA` if `threshold = NULL`).
