truncateTransform {flowCore} | R Documentation |
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.
truncateTransform(transformationId="defaultTruncateTransform", a=1)
transformationId |
character string to identify the transformation |
a |
double that corresponds to the value at which to truncate |
Returns an object of class transform
.
