Examples

## Create a count matrix
A1 <- matrix(data = as.numeric(sample(1:100, 100, TRUE)), nrow = 20)

## Coerce to compositions
B <- as_composition(A1)

## Row sums are internally stored before coercing to relative frequencies
get_totals(B)
#>  [1] 222 134 202 295 234 373 210 237 237 308 211 342 140 340 218 374 239 210 232
#> [20] 238

## This allows to restore the source data
A2 <- as_amounts(B)

## Coerce to a data.frame
X <- data.frame(B)
head(X)
