In DDHFm: Variance Stabilization by Data-Driven Haar-Fisz (for Microarrays)

Find index where two vectors are closest

Description

Finds the index point where two index vectors are closest in value

Usage

which.min.diff(a, vect)

Arguments

a	input vector
vect	input vector

Value

The index where abs(a-vect) is smallest, ie where a and vect are smallest.

Examples

#
# Make up two vectors
#
a <- c(1,2,3)
vect <- c(3,2,1)
#
# Now see on which index are the two closest in value 
#
which.min.diff(a,vect)
#[1] 2
#
# ie its the second index where both vectors are actually 2
