Summary group generic for dual numbers

Source: R/dual-arithmetic.R

Implements sum, prod, min, max, range, any, and all for dual numbers. Derivatives are propagated correctly through sum (additive) and prod (multiplicative).

# S4 method for class 'dualr'
Summary(x, ..., na.rm = FALSE)

Arguments

x

A dual number.

...

Additional dual or numeric values.

na.rm

Logical; ignored (present for generic compatibility).

Value

A dual for sum/prod/min/max; a dual_vector for range; logical for any/all.

Examples

x <- dual_variable(2)
y <- dual_variable(5)
value(sum(x, y))   # 7
#> [1] 7
value(prod(x, y))  # 10
#> [1] 10
