Drawing filter regions

Description

These methods extend the basic graphics polygon methods for drawing of filter regions. They allow for multiple dispatch, since not all filter types need to be evaluated for plotting, but this decision should be made internally.

Details

When plotting code{flowFrame}s using the plot method provided by flowViz, the plotted parameters are recorded, which makes it possible to correctly overlay the outlines of filters assuming that they are defined for the repective parameters. Warnings and error will be cast for the cases where the parameters are non-distinct or ambigious.

Methods

x = "filter", data = "missing"

General method for all objects inheriting from filter. This is used as the default when no more explicit method is found. It tries to find the plotted parameters from the internal flowViz.state environment. This only works if the flow data has been plotted using the plot methods provided by this flowViz package.

x = "filterResult", data = "missing"

General method for all filterResult object. This basically extracts the filter from the filterResult and dispatches on that.

x = "filterResult", data = "flowFrame"

For some filter types we need the raw data to re-evaluate the filter.

x = "curv1Filter", data = "ANY"

We either need a filterResult or the raw data as a flowFrame for curv1Filters.

x = "curv1Filter", data = "flowFrame"

see above

x = "curv1Filter", data = "missing"

see above

x = "curv1Filter", data = "multipleFilterResult"

see above

x = "curv2Filter", data = "ANY"

We either need a filterResult or the raw data as a flowFrame for curv2Filters.

x = "curv2Filter", data = "flowFrame"

see above

x = "curv2Filter", data = "multipleFilterResult"

see above

x = "kmeansFilter", data = "ANY"

We don't know how to plot regions of a kmeansFilter, hence we warn.

x = "norm2Filter", data = "ANY"

We either need a filterResult or the raw data as a flowFrame for norm2Filters.

x = "norm2Filter", data = "flowFrame"

see above

x = "norm2Filter", data = "logicalFilterResult"

see above

x = "polygonGate", data = "character"

We can plot a code{linkS4class{polygonGate}} directly from the gate definition.

x = "polygonGate", data = "filterResult"

see above

x = "polygonGate", data = "flowFrame"

see above

x = "quadGate", data = "character"

We can plot a code{linkS4class{quadGate}} directly from the gate definition.

x = "quadGate", data = "filterResult"

see above

x = "quadGate", data = "flowFrame"

see above

x = "rectangleGate", data = "character"

We can plot a code{linkS4class{rectangleGate}} directly from the gate definition.

x = "rectangleGate", data = "filterResult"

see above

x = "rectangleGate", data = "flowFrame"

see above
