calculateFDR: Calculate FDR Cutoffs
In propr: Calculating Proportionality Between Vectors of Compositional Data

This function uses the result of a permuteTheta call to calculate false discovery rate (FDR) cutoffs.

1	calculateFDR(theta, ptheta, cutoff = seq(0.6, 0.9, 0.1))

`theta`	A `data.frame`. The result of a `calculateTheta` call.
`ptheta`	A `data.frame`. The result of a `permuteTheta` call.
`cutoff`	For `updateCutoffs`, a numeric vector. this argument provides the FDR cutoffs to test. For graph functions, a numeric scalar. This argument indicates the maximum theta to include in the figure. For graph functions, a large integer will instead retrieve the top N pairs as ranked by theta.
