    words <- strsplit("Hello wOrld", " ")[[1]];
    cat(paste(toupper(words), collapse=" "), "\n")      # "HELLO WORLD"

    stopifnot(paste(toupper(words), collapse=" ") == "HELLO WORLD")
    stopifnot(paste(tolower(words), collapse=" ") == "hello world")
    stopifnot(paste(capitalize(words), collapse=" ") == "Hello WOrld")
    stopifnot(paste(decapitalize(words), collapse=" ") == "hello wOrld")
