scaleTransform {flowCore} | R Documentation |
Create the definition of the scale Transformation that will be applied on
some parameter via the transform
method. The definition of this
function is currently x = (x-a)/(b-a). The transformation would normally be
used to convert to a 0-1 scale. In this case, b would be the maximum
possible value and a would be the minimum possible value.
scaleTransform(transformationId="defaultScaleTransform", a, b)
transformationId |
character string to identify the transformation |
a |
double that corresponds to the value that will be transformed to 0 |
b |
double that corresponds to the value that will be transformed to 1 |
Returns an object of class transform
.
