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)
