filter8text: filters components of a character.

In rbsa: Ancillary Functions for R Programming

Description

For each component of a character vector, checks with function belong9 if it satisfies the conditions given by the other arguments, the component is removed (or selected).

Usage

 
  filter8text(text,pattern,remove=TRUE,
              exact=FALSE,how="a",lower=FALSE,
              monitor=rbsa0$monitor$v) 

Arguments

text	The character to be filtered.
pattern	(character) the character string(s) to be found in each component.
remove	Must the conforming components be removed (or selected)?
exact	When exact, one component must be strictly identical, if not a subtring is sufficient.
how	Indicates what to do when length(sch)>1. The choice are v: a logical vector gives back each check independently; 1: returns TRUE when at least one of the component belongs to the series ch and a when all components must comply to get TRUE.
lower	Must the comparisons being done after case lowering?
monitor	List of constants indicating the monitoring choices, see the rbsa0$monitor$v provided object as an example.

Value

A character comprising the non-removed (or selected) components of the initial components.
