ASCII characters: from decimal code to R octal?
David Firth <david.firth at nuffield.oxford.ac.uk> writes:
Is there a straightforward way to convert character information from decimal representation to the octal one used by R? I'd like something like a function ascii(number,base=10), such that
ascii(91)
[1] "\133" I can easily do the mapping from 91 to 133, but what is a good way to operate on 133 to deliver "\133"? Would a lookup table be a better solution?
Stuff like this can do it:
ascii <- sapply(1:127,function(i)
parse(text=paste("\"\\",structure(i,class="octmode"),"\"",sep=""))[[1]])
ascii[91]
