TileCalcWinMedian

Description

Calculates median on probe scores with window indices.

Usage

TileCalcWinMedian(int, win.idx)

Arguments

int A numeric vector containing one or more probe scores (i.e. intensities or log-fold changes).
win.idx A list with the maximal number of probes in a window as its length. In entry i, it stores only start positions of windows containing at least (i+1) probes.

Details

Calculates median on probe scores with window indices, a list storing window start positions. More precisely, win.idx has the maximal number of probes in a window as length and in its ith entry, it stores only start positions of windows containing at least (i+1) probes. In case of short but numerous windows, the window scores can be calculated very efficiently by use of optimized vector operations. Otherwise, please consider using TileCalcWinMedian2 instead.

Value

A numeric vector containing the median of the window scores for each possible start position. Note that windows of length zero are not supported and hence treated as windows of length one. Moreover, probe scores with the value NA are excluded from the calculation.
