Encoding in R like Python ("ord" and "chr") -

i wondering how encoding , decoding in r. in python, can use ord('a') , chr(97) transform letter number or transform number letter. know similar functions in r? thank you!

for example, in python

>>>ord("a")

97

>>>ord("a")

65

>>>chr(97)

'a'

>>>chr(90)

'z'

fyi: ord(c) in python given string of length one, return integer representing unicode code point of character when argument unicode object, or value of byte when argument 8-bit string. example, ord('a') returns integer 97, ord(u'\u2020') returns 8224. inverse of chr() 8-bit strings , of unichr() unicode objects. if unicode argument given , python built ucs2 unicode, character’s code point must in range [0..65535] inclusive; otherwise string length two, , typeerror raised.

chr(i) in python return string of 1 character ascii code integer i. example, chr(97) returns string 'a'. inverse of ord(). argument must in range [0..255], inclusive; valueerror raised if outside range. see unichr().

you're looking utf8toint , inttoutf8

utf8toint("a") [1] 97  inttoutf8(97) [1] "a"
