Row Sums

Retrieves or defines the row sums (before closure ). methods

totals(object)

totals(object) <- value

## S4 method for signature 'CompositionMatrix'
totals(object)

## S4 method for signature 'LogRatio'
totals(object)

## S4 replacement method for signature 'CompositionMatrix'
totals(object) <- value

Arguments

• object: An object from which to get or set totals.
• value: A possible value for the totals of x.

Returns

• totals() \<- value returns an object of the same sort as x with the new row sums assigned.
• totals() returns the row sums of x.

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)

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

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