ssWithin: Calculate Within-Group Log-ratio Sums of Squares

In balance: Visualize Balances of Compositional Data

Description

This function calculates the within-group sums of squares for all variables or all log-ratios. This function only supports binary outcomes.

Usage

ssWithin(x, group, pairwise = FALSE, ...)

Arguments

x	A matrix with rows as samples (N) and columns as components (D).
group	A character vector. Group or sub-group membership. Argument passed to propr::propd.
pairwise	A logical. Toggles whether to decompose sums of squares for each log-ratio.
...	Other arguments passed to propr::propd.

Value

If pairwise = FALSE, this function returns a vector of the sums of squares for each variable. If pairwise = TRUE, this function returns a matrix of the sums of squares for each log-ratio.
