findintervals: Find Interval Indices

Description

Find indices i in vector xs such that either x=xs[i] or such that xs[i] or xs[i]>x>xs[i+1].

Usage

findintervals(x, xs)

Arguments

x

single number.

xs

numeric vector, not necessarily sorted.

Value

• Vector of indices in 1..length(xs). If none is found, returns integer(0).

Details

Contrary to findInterval, the vector xs in findintervals need not be sorted.

Examples

xs <- zapsmall(sin(seq(0, 10*pi, len=100)))
findintervals(0, xs)
#   1  10  20  30  40  50  60  70  80  90 100
