Arguments

TPs, x, obj, object

transformationProducts object to be accessed

i, j

For [/[[: A numeric or character value which is used to select parents by their index or name, respectively (for the order/names see names()).

For [: Can also be logical to perform logical selection (similar to regular vectors). If missing all parents are selected.

For [[: should be a scalar value.

For delete: The data to remove from. i are the parents as numeric index, logical or character, j the transformation products as numeric index (row) or name of the TP. If either is NULL then data for all is removed. j may also be a function: it will be called for each parent, with the TP info table (a data.table), the parent name and any other arguments passed as ... to delete. The return value of this function specifies the TP indices (rows) (specified as an integer or logical vector) or names to be

...

For delete: passed to the function specified as j. Otherwise ignored.

drop

ignored.

name

The parent name (partially matched).

includeParents

If TRUE then parents are also included in the returned suspect list.

properties

A named list with properties to be filtered. Each item in the list should be named with the name of the property, and should be a vector with allowed values. To obtain the possible properties, run e.g. names(TPs)[[1]]. Example: properties=list(likelihood=c("LIKELY","PROBABLE")). Set to NULL to ignore.

verbose

If set to FALSE then no text output is shown.

negate

If TRUE then filters are performed in opposite manner.

Value

delete returns the object for which the specified data was removed.

filter returns a filtered transformationProducts object.

Details

This class holds all generated data for transformation products for a set of parents. The class is virtual and derived objects are created by TP generators.

Methods (by generic)

  • parents(transformationProducts): Accessor method for the parents slot of a transformationProducts class.

  • products(transformationProducts): Accessor method for the products slot.

  • length(transformationProducts): Obtain total number of transformation products.

  • names(transformationProducts): Obtain the names of all parents in this object.

  • show(transformationProducts): Show summary information for this object.

  • x[i: Subset on parents.

  • x[[i: Extracts a table with TPs for a parent.

  • $: Extracts a table with TPs for a parent.

  • as.data.table(transformationProducts): Returns all TP data in a table.

  • convertToSuspects(transformationProducts): Converts this object to a suspect list that can be used as input for screenSuspects.

  • delete(transformationProducts): Completely deletes specified transformation product data.

  • filter(transformationProducts): Performs rule-based filtering. Useful to simplify and clean-up the data.

Slots

parents

A data.table with metadata for all parents that have TPs in this object. Use the parents method for access.

products

A list with data.table entries with TP information for each parent. Use the products method for access.
