totals {compositions} | R Documentation

## Total sum of amounts

### Description

Calculates the total amount by summing the individual parts.

### Usage

    totals(x,...)
    ## S3 method for class 'acomp':
    totals(x,...,missing.ok=TRUE)
    ## S3 method for class 'rcomp':
    totals(x,...,missing.ok=TRUE)
    ## S3 method for class 'aplus':
    totals(x,...,missing.ok=TRUE)
    ## S3 method for class 'rplus':
    totals(x,...,missing.ok=TRUE)

### Arguments

`x` | an amount/amount dataset
`...` | not used, only here for generic purposes
`missing.ok` | if TRUE ignores missings; if FALSE issues an error if the total cannot be calculated due to missings.

### Value

a numeric vector of length equal to `ncol(x)` containing the total amounts

### Missing Policy

if `missing.ok=TRUE` missings are just regarded as 0, if `missing.ok=FALSE` WZERO values is still regarded as 0 and other sorts lead to `NA` in the respective totals.
