Easily display fraction and percentages

Description

For a subset 'n' and total 'N', nicely prints text n/N and/or percentage Often we want to display proportions and this simple function reduces the required amount of code for fraction and percentage reporting. If insufficient digits are provided small percentage may truncate to zero.

Usage

1
out.of(n, N = 100, digits = 2, pc = TRUE, oo = TRUE, use.sci = FALSE)

Arguments

n

numeric, the count for the subset of N (the numerator)

N

numeric, the total size of the full set (the denominator)

digits,

integer, the number of digits to display in the percentage

pc,

logical, whether to display the percentage of N that n comprises

oo,

logical, whether to display n/N as a fraction

use.sci,

logical, whether to allow scientific notation for small/large percentages.

Value

A string showing the fraction n/N and percentage (or just one of these)

out.of(345,12144)
out.of(345,12144,pc=FALSE)
out.of(3,10^6,digits=6,oo=FALSE)
