Here is my attempt at this (taking a specific understanding of the ill- defined "equivalence" relation),

unletter <- function(word){         

	word.broken <- strsplit(word, NULL)
	set.of.numbers <- sapply(word.broken[[1]], function(let) which(let ==  
letters))
	paste(set.of.numbers, sep="", collapse="")
}

unletter("abc")
# "123"

unletter("xyz")
# "242526"
unletter("salut")

# "191122120"
