generalized_log: Generalized log transform data.

In cytominer: Methods for Image-Based Cell Profiling

Description

generalized_log transforms specified observation variables using x = log( (x + sqrt(x ^ 2 + offset ^ 2 )) / 2 ).

Usage

generalized_log(population, variables, offset = 1)

Arguments

population	tbl with grouping (metadata) and observation variables.
variables	character vector specifying observation variables.
offset	optional offset parameter for the transformation.

Value

transformed data of the same class as population.

Examples

population <- tibble::tibble(
  Metadata_Well = c("A01", "A02", "B01", "B02"),
  Intensity_DNA = c(8, 20, 12, 32)
)
variables <- c("Intensity_DNA")
generalized_log(population, variables)
