n.code

Convert "Round" Integers to Short Strings and Back

Description

n.code convert “round integers” to short character strings. This is useful to build up variable names in simulations, e.g.

code2n is the inverse function of n.code().

Usage

n.code(n,    ndig = 1, dec.codes = c("", "d", "c", "k"))
code2n(ncod, ndig = 1, dec.codes = c("", "d", "c", "k"))

Arguments

`n`	integer vector.
`ncod`	character vector, typically resulting from `n.code`.
`ndig`	integer giving number of digits before the coding character.
`dec.codes`	character code for 1, 10, 100, 1000 (etc).

Value

n.code(n) returns a character vector of the same length as n.

code2n(ncod) returns a integer vector of the same length as ncod.

Usually, code2n(n.code(n)) == n.

Examples

n10 <-  c(10,20,90, 100,500, 2000,10000)
(c10 <- n.code(n10))#-> "1d" "2d" "9d" "1c" ..
stopifnot(code2n(c10) == n10)
