truncateTransform: Create the definition of a truncate transformation function...

In flowCore: flowCore: Basic structures for flow cytometry data

Description

Create the definition of the truncate Transformation that will be applied on some parameter via the transform method. The definition of this function is currently x[x<a] <- a. Hence, all values less than a are replaced by a. The typical use would be to replace all values less than 1 by 1.

Usage

truncateTransform(transformationId="defaultTruncateTransform", a=1)

Arguments

transformationId	character string to identify the transformation
a	double that corresponds to the value at which to truncate

Value

Returns an object of class transform.
