ruv_ecdf: RUV P-value Empirical CDF Plot
In ruv: Detect and Remove Unwanted Variation using Negative Controls

Plots an ECDF of p-values returned by a call to ruv_summary

1	ruv_ecdf(fit, X.col = "all", power = 1, uniform.lines = 0)

`fit`	The results of a call to `ruv_summary`.
`X.col`	Which column of the X matrix to make the plot for, i.e. which factor's p-values to plot. Can be either an integer or a character string. Or, if "all" (the default), use the F-test p-values.
`power`	A power transformation of the x and y axes. For example, set to 1/2 for a square-root transformation. This can help to see the behavior of the ECDF near 0.
`uniform.lines`	A vector of values between 0 and 1, or NULL. If specified, light gray lines will be drawn, showing (locally) uniform distributions.
