apply_scale: Apply a scale transformation to numeric columns

In CytoProfile: Cytokine Profiling Analysis Tool

Apply a scale transformation to numeric columns

Description

This helper function applies a chosen scaling or transformation to specified numeric columns in a data frame. Supported built‑in transformations include no transformation ("none"), log2, log10, and z‑score scaling. A custom function can also be supplied to perform arbitrary transformations.

Usage

apply_scale(
  data,
  columns = NULL,
  scale = c("none", "log2", "log10", "zscore", "custom"),
  custom_fn = NULL
)

Arguments

data	A data.frame or matrix containing the data to be transformed.
columns	A character vector of column names to transform. If NULL (default) all numeric columns will be transformed.
scale	A character string specifying the transformation to apply. Possible values are "none", "log2", "log10", "zscore", or "custom". When set to "custom" the function specified in custom_fn will be applied to the columns.
custom_fn	A function that takes a numeric vector and returns a transformed numeric vector. Only used when scale = "custom".

Value

A data.frame with the same dimensions as data with transformed numeric columns.
