## Extraction of slot information using "[["

### Description

Specifically this method is able to extract components or slots.

ANY.object[1] retrieves the first element or slot

FCSmetadata.object["fcsinfo"] obtains the "fcsinfo" slot which is a list

FCSmetadata.object["$P1R"] obtains the first parameter range/max

FCSmetadata.object[1:10] obtains first 10 elements of the "fcsinfo" slot of the metadata

FCS.object[1,2:3] extracts/reduces the data of the "FCS-class" object

### Methods

x = "ANY"
  extracts elements
x = "FCSmetadata"
  Extracts slot information.

  If using a single character string index such as the slotNames ("mode" or "$MODE"; "size" or "$TOT"; "nparam" or "$PAR"; "longnames" or "$PnS" or "$P1S" or "$P2S" etc...; "shortnames"or "$PnN" or "$P1N" or "$P2N" etc...; "paramranges" or "$PnR" or "$P1R" or "$P2R" etc...;"fcsinfo";"objectname", "original", "filename") as well as the "fcsinfo" slotNames can be retrieved.

  If using a numeric single-valued or numeric vector index, only the "fcsinfo" slots are numerically indexed and can be retreived.

x = "FCS"
  extracts the slot information from the metadata portion of the object; see x="FCSmetadata" description (above) for specific indexing using "[["
x="PRIM.step"
  extracts the object via a character slot name and/or a numeric iteration ID

x="PRIM.step.set", y="missing"
  extracts the object via a character slot name for the step (ie, "peel.step" or "expand.step") and with an optional slot name for the "PRIM.step" object.
x="PRIM.crossval.step", y="missing"
  extracts the object via a character slot name and/or a numeric testdata ID
