indexesInRange {bsearchtools}

R Documentation

Find indexes in a range using binary search

Description

Given a sorted vector, it returns the indexes of the vector elements included in range [lbInclusive,ubInclusive].

The functions suffixed with the vector type (indexInRangeNumeric,indexInRangeLogical etc.) can be used ONLY with the specified type, otherwise the vector is coerced, and they are (hopefully negligibly) faster then the generic indexInRange function.

Usage

indexesInRange(sortedValues,lbInclusive, ubInclusive,indexesRemap=NULL)
indexesInRangeNumeric(sortedValues,lbInclusive, ubInclusive,indexesRemap=NULL)
indexesInRangeInteger(sortedValues,lbInclusive, ubInclusive,indexesRemap=NULL)
indexesInRangeLogical(sortedValues,lbInclusive, ubInclusive,indexesRemap=NULL)
indexesInRangeCharacter(sortedValues,lbInclusive, ubInclusive,indexesRemap=NULL)

Arguments

sortedValues	A sorted atomic vector of type numeric, integer, logical or character
lbInclusive	The inclusive lower bound of the range
ubInclusive	The inclusive upper bound of the range
indexesRemap	An integer vector to be used to remap the indexes returned by lookup on sortedValues, or NULL (the default). Mostly used internally by DFI.

Value

The indexes of the vector elements included in range [lbInclusive,ubInclusive].

Examples

indexesInRange(c(1,4,5,5,7,9),5,7) # returns c(3,4,5)
indexesInRange(c(1,4,5,5,7,9),10,11) # returns empty vector
