sum0: Sum of Vector Elements with alternative empty-set definition

In sumtxt/datatools: Functions I use a lot when working with data in R

Description

Sum of Vector Elements with alternative empty-set definition

Usage

sum0(x, na.rm = TRUE)

Arguments

x	numeric, complex or logical vector
na.rm	logical. Should missing values (including NaN) be removed?

Value

scalar sum of all values in x. Different to sum, the sum of an empty set is undefined (see example). This is helpful for aggregating count data across observations that are nested in groups and for some groups all observations are missing

Examples

 x <- c(NA,NA,NA)
 sum(x,na.rm=TRUE)
 sum0(x,na.rm=TRUE)
