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.
transforms
:A list of transforms to perform on the
target flowFrame
filter
:The filter to be applied to the transformed frame
filterId
:The name of the filter (chosen automatically)
Class "filter"
