Here is a series of `cat` statements

```
words = c("Hello","bar","ROCKnROLL","R","Supercalifragilisticexpialidocious")
for (i in 1:length(words))
{
    cat(paste0(words[i], "\t: ",nchar(words[i]),"\n"))
}

Hello   : 5
bar : 3
ROCKnROLL   : 9
R   : 1
Supercalifragilisticexpialidocious  : 34

```

How would I do to align them like this

```
Hello                               : 5
bar                                 : 3
ROCKnROLL                           : 9
R                                   : 1
Supercalifragilisticexpialidocious  : 34

```

or like this

```
                             Hello  : 5
                               bar  : 3
                         ROCKnROLL  : 9
                                 R  : 1
Supercalifragilisticexpialidocious  : 34

```

or eventually like this

```
             Hello                  : 5
              bar                   : 3
           ROCKnROLL                : 9
               R                    : 1
Supercalifragilisticexpialidocious  : 34

```
