Hi Lin,
I got bored after the millions, but this should handle the smaller
numbers, and you can always extend it.
digits2text<-function(x,mult="") {
units<-c("one","two","three","four","five",
"six","seven","eight","nine")
teens<-c("ten","eleven","twelve","thirteen","fourteen",
"fifteen","sixteen","seventeen","eighteen","nineteen")
tens<-c("ten","twenty","thirty","forty","fifty",
"sixty","seventy","eighty","ninety")
digits<-rev(as.numeric(strsplit(as.character(x),"")[[1]]))
digilen<-length(digits)
if(digilen == 2 && digits[2] == 1) return(teens[digits[1]+1])
digitext<-units[digits[1]]
if(digilen > 1) digitext<-c(digitext,tens[digits[2]])
if(digilen > 2) digitext<-c(digitext,"hundred",units[digits[3]])
if(digilen > 3) digitext<-
c(digitext,digits2text(floor(x/1000),"thousand"))
if(digilen > 6) digitext<-
c(digitext,digits2text(floor(x/1000000),"million"))
return(paste(c(rev(digitext),mult),sep="",collapse=" "))
}
