Can you give an example? I don't understand either what sort of  
conversion you desire or what you mean by "convert it based on a given  
type."

There are a couple of function you may want to consider but I am  
having difficulty convincing myself they answer the problem posed:

?charToRaw
?stroi

 > strtoi(charToRaw("123 this is a string"), base=16)   # convert to  
decimal ASCII
  [1]  49  50  51  32 116 104 105 115  32 105 115  32  97  32 115 116  
114 105 110 103
