Split a diffFeatureGroups data.frame into a list of two featureGroups data.frames, which can then be passed to simphony().

## Usage

splitDiffFeatureGroups(diffFeatureGroups, checkValid = TRUE)

## Arguments

diffFeatureGroups

data.frame with optional columns meanBase, dBase, meanSd, dSd, meanAmp, dAmp, meanPhase, and dPhase describing the changes in abundance between two conditions. Each row corresponds to a group of features.

checkValid

Logical for whether to only return rows for which both amplitudes are greater than or equal to zero and both standard deviations are greater than zero.

## Value

List of two data.tables with possible columns base, sd, amp, and phase, depending on the columns in diffFeatureGroups.

dGroups = data.frame(meanAmp = c(1, 1, 1, 1), dAmp = c(1, 1, 2, 2),
