Description

Given a (potentially very long) vector, the vector is partitioned into a given number of (up to rounding errors) equally long bins, and a vector summerizing each of the bins with one number it returned.

Usage

1
shrinkVector(vec, newLength,  mode = c("max", "min", "absmax", "mean"))

Arguments

vec

The vector to be shrunk. May be an ordinary numeric or integer vector or an IRanges::Rle vector.

newLength

The desired size of the return vector, i.e., the number of partitions

mode

the summerization mode: 'max': take the maximal value of each bin; 'min': take the minimal value of each bin; 'absmax': take the value with largest absolute value; 'mean': take the mean of the bin values.

Value

A vector of length newLength with the summary values of each of the bin of vector.
