smedian.sample: Calculate the median of the sampled values with replacement...

In KrasnitzLab/CNprep: Pre-process DNA Copy Number (CN) Data for Detection of CN Events

Calculate the median of the sampled values with replacement from a contiguous subsection of specified vector.

Description

Calculate the median of the sampled values with replacement from a specified vector. Only a contiguous subsection of the vector is used for the sampling, as the first and last position are set by user.

Usage

smedian.sample(pos, v)

Arguments

pos	a vector of 2 integer that represent the first and last positions of vector v to used for the sampling step.
v	a vector of double containing the values used for sampling. However, only a subsection of the vector, as set by pos, is used.

Value

a double which is the median of the sampled values.

Examples

## A vector with the first and last positions to subset the value vector
position <- c(1, 10)

## A value vector used to do sampling with replacement
values <- c(0.072073840, 0.119913919, 0.154459489, 0.040994620, 
    -0.082843732, 0.093052725, 0.170908930, 0.086624752, -0.003855011,
