Performs a log transform on a numeric vector.

Usage

log_CT_orig(x, na.rm = FALSE)

Arguments

x: A numeric vector.
na.rm: Set TRUE to remove NA values, otherwise returns NA.

Value

A log-transformed vector of data, and treatment details wrapped in a list.

Details

Specifically, this performs a "COIN Tool log" transform: log(x-min(x) + 1).
