arcsinhTransform {flowCore} | R Documentation |
Create the definition of the arcsinh Transformation that will be
applied on some parameter via the transform
method.
The definition of this function is currently x<-asinh(a+b*x)+c).
The transformation would normally be used to convert to a linear valued parameter
to the natural logarithm scale. By default a and b are both equal to 1 and c to 0.
arcsinhTransform(transformationId, a=1, b=1, c=0)
transformationId |
character string to identify the transformation |
a |
positive double that correponds to the base of the logarithm. |
b |
positive double that correponds to a scale factor. |
c |
positive double that correponds to a scale factor |
Returns an object of class transform
.
