balanced: Balanced operator

Description

Makes a function balance the removal of NAs across multiple input vectors.

Usage

balanced(f, ...)

Value

A function like f with a new argument na.rm. If na.rm = TRUE then complete.cases() is used to remove missing values across all inputs prior to calling f.

Arguments

f

A function.

...

Deprecated. Additional arguments to f that should not be balanced.

Other operators: grouped(), quantity_index()

Examples

p1 <- price6[[3]]
p0 <- price6[[2]]
q1 <- quantity6[[3]]
q0 <- quantity6[[2]]

# Balance missing values for a Fisher index

fisher <- balanced(fisher_index)
fisher(p1, p0, q1, replace(q0, 3, NA), na.rm = TRUE)
fisher_index(p1[-3], p0[-3], q1[-3], q0[-3])

# Operators can be combined, but some care may be needed

x <- 1:6
w <- c(1:5, NA)

f <- factor(rep(letters[1:2], each = 3))

grouped(\(x, w) balanced(fisher_mean)(x, w, na.rm = TRUE))(x, w, group = f)
balanced(grouped(fisher_mean))(x, w, group = f, na.rm = TRUE)
