totals(object) <- value

Arguments

object

Examples

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

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

## Row sums are internally stored before coercing to relative frequencies
totals(B)
#>  [1] 120 249 275 232 305 386 204  55 378 261 309 283 328 226 314 327 327 172 238
#> [20] 190

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

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