roc.FLVector: ROC. 'roc' performs ROC on FLvectors and FLTable objects.

In Fuzzy-Logix/AdapteR: Converts R syntax to SQL to provide fast analytics using in-database C++ library DB Lytix.

Description

The DB Lytix function called is FLROC. Performs ROC and stores the results in predefined tables. This function's main job is to build a ROC object. Data can be provided as 'response', 'predictor', where the predictor is the numeric (or ordered) level of the evaluated signal, and the response encodes the observation class (control or case).

Usage

## S3 method for class 'FLROC'
print(response, predictor, ...)

Arguments

formula	A symbolic description of model to be made.
data	An object of class FLTable.

Value

roc returns an object of class FLROC

Slots

results

cache list of results computed

votbl

stores the table names of output ROC table.

See Also

roc for R reference implementation.

Examples

tbl <- FLTable("tblROCCurve", "ObsID")
mod <- roc(tbl$ActualVal, tbl$ProbVal)
