However, if you insist, this seems to do it:
> as.character(as.octmode(as.integer(charToRaw(paste(x,collapse="")))))
[1] "002" "001" "102"
> str(as.character(as.octmode(as.integer(charToRaw(paste(x,collapse=""))))))
chr [1:3] "002" "001" "102"
> x
[1] "\002" "\001" "B"
(NB Octal code "\102" is a "B".)
Or, as I suspect the above is doing internally:
> sprintf("%03o", as.integer(charToRaw(paste(x,collapse=""))))
[1] "002" "001" "102"
