And the first example works for you?
require("base64enc")
s <- "saf"
x <- base64encode(s)
## Error in file(what, "rb") : cannot open the connection
## In addition: Warning message:
## In file(what, "rb") : cannot open file 'saf': No such file or directory
?base64encode says that its first argument is
"data to be encoded/decoded. For ‘base64encode’ it can be a raw
vector, text connection or file name. For ‘base64decode’ it can be
a string or a binary connection."
Try this:
rawToChar(base64decode(base64encode(charToRaw("saf"))))
## [1] "saf"
