seabird R Documentation
Calculate ROC area-under-curve for X-chromosome sex differences (internal function for calculating the seabi metric)
Description
This is a wrapper for the prediction and performance functions from
the ROCR package that takes a vector of p-values and a vector of true
or false for being on the X. See seabi function which does everything.
Usage
seabird(pr, stop = 1, X)
Arguments
pr
a vector of p-values, such as calculated by seabird
stop
fraction for partial area under curve. For example 0.1 gives you the
area for the lowest 10% of p-values.
X
logical vector the same length as pv, true for features mapped to X-chromosome
Value
Returns an area value between 0 and 1, where 1 is the best possible performance.
