internals: Internal functions and methods

Description

These functions and methods are used internally and should usually not be called from outside the package.

Usage

begin(x, ...)
  nextPairs(x, n = 10000, ...)
  clear(x, ...)
  blockfldfun(blockfld, phoneticFld, phoneticFun, coln)
  getSQLStatement(object)
  init_sqlite_extensions(db)
  .allows_extensions(db)
  .lib_path()
  getPatternCounts(x, n=10000, cutoff=1, withProgressBar = (sink.number()==0))
  getMatchCount(object)
  getNACount(object)
  getDbFile(object)
  getColumnNames(object, withExcluded = FALSE)
  getThresholds(W, M, U, my, ny)
  countpattern(x, matching = FALSE)

Arguments

x, object

A "RLBigData" object (also "RLResult" for getDbFile. A matrix of binary observations for countpattern.

Maximum number of comparison patterns to fetch.

blockfld

Blocking definition as in RLBigData*.

phoneticFld

Indices of attributes for which phonetic code should be used.

phoneticFun

Name of phonetic function as in RLBigData*.

coln

Column names of records.

Database connection.

cutoff

Threshold from which string comparison values are rounded to 1.

withProgressBar

Whether to display a progress bar.

withExcluded

Logical. Wether to output names of excluded columns

W,M,U

Linkage weights, m- and u-probabilites. See emWeights for details.

W,M,U

Error bounds. See emClassify for details.

...

Optional arguments.

matching

If TRUE an additional vector is returned which stores which row belongs to which pattern.
