transformFilter-class {flowCore} | R Documentation |
The transformFilter
class is a mechanism for including one or
more variable transformations into the filtering process. Using a
special case of transform
we can introduce
transformations inline with the filtering process eliminating the need
to process flowFrame
objects before applying a
filter.
Objects of this type are not generally created ``by hand''. They are a
side effect of the use of the %on%
method
with a filter
object on the left hand side and
a transformList
on the right hand side.
