power.plot: Provides plot of Estimated Power vs Sample Size In RSPS: RNA-Seq Power Simulation

Description

This function plots the estimate power vs sample size computed using function poiss.pow or negbin.pow for different fold changes. Please see example on how to use it.

Usage

 `1` ```power.plot(fit, ylim = c(-0.05, 1.05), cutoff = 0.8) ```

Arguments

 `fit` Function used to estimate the power. See example. `ylim` Limits of y-axis `cutoff` Cutoff value for power

Details

This function can only be run if the function poiss.pow or negbin.pow has been used. If a vector of type I error, null count, and overdispersion (for negbin.pow) is provided the plot is based on the smalles of these values.
