ceil_at: Rounding with predefined thresholds

In polettif/proporz: Proportional Apportionment

Rounding with predefined thresholds

Description

Round x up to ceiling(x) if x-floor(x) >= threshold, otherwise round down to floor(x).

Usage

ceil_at(x, threshold)

Arguments

x	numeric vector or matrix >= 0 (NaN is not supported)
threshold	threshold in [0,1] or "harmonic"/"geometric" to use harmonic or geometric mean thresholds

Value

the rounded vector or matrix

Examples

ceil_at(c(0.5, 1.5, 2.49, 2.5, 2.51), 0.5)
# compare to
round(c(0.5, 1.5, 2.49, 2.5, 2.51))

ceil_at(c(1.45, 2.45, 3.45), 0) # like floor()
ceil_at(c(1.45, 2.45, 3.45, 0.2), "geometric")
