gateView-class {flowCore} | R Documentation |
Class and method to capture the result of gating operations in a flow cytometry workflow.
gateView(workflow, ID=paste("gateViewRef", guid(), sep="_"), name="default", action, data, indices, filterResult, frEntry)
workflow |
An object of class |
ID |
A unique identifier of the view, most likely created by
using the internal |
name |
A more human-readable name of the view. |
data, action, filterResult |
References to the data,
|
indices |
A logical vector of indices in the parent data. |
frEntry |
A character vector indicating the name of the
population in the |
gateViews
provide a means to bind the results of gating
operations in a workflow. Each gateView
represents one of the
populations that arise from the
gating. logicalFilterResults
create two gateViews
(events in the gate and events not in the
gate),
multipleFilterResults
one view
for each population. See the documentation of the
parent class view
for more details.
A reference to the gateView
that is created inside the
workFlow
environment as a side effect of calling the
add
method.
A gateView
object for the constructor.
Objects should be created using the add
method, which creates a
gateView
from a filter
object and directly
assigns it to a workFlow
. Alternatively, one can use the
gateView
constructor function for more programmatic access.
indices
:Object of class "logical"
. The indices
in the parent data for events that are within the filter.
filterResult
:Object of class
"fcFilterResultReference"
. A reference to the outcome of
the filtering operation.
frEntry
:Object of class "character"
The
population in the filterResult
that corresponds to the
current view. See details for further explanation.
ID
:Object of class "character"
. A unique
identifier for the view.
name
:Object of class "character"
. A more
human-readable name
action
:Object of class "fcActionReference"
. A
reference to the
actionItem
that generated
the view.
env
:Object of class "environment"
. The
evaluation environment in the
workFlow
.
data
:Object of class "fcDataReference"
A
reference to the data that is associated to the view. Subsets of
the data are only generated when a a further action is invoked on
a particular gateView
. Summary statistics about the view
can be acquired through the usual process of summarizing
filterResults
.
Class "view"
, directly.
signature(symbol = "gateView", envir = "workFlow",
subSymbol = "character")
: Remove a gateView
from a
workFlow
. This method is recursive and will also
remove all dependent views
and
actionItem
s.
signature(x = "formula", data = "gateView")
:
Summarize the gating operation.
signature(x = "formula", data = "gateView")
:
Plot the data of the gateView
along with the gate.
