Convert ASCII Codes to Characters and Vice Versa
AscToChar returns a character for each ASCII code (integer) supplied.
CharToAsc returns integer codes in 0:255
for each (one byte) character in all strings in x
.
AscToChar(i) CharToAsc(x)
i |
numeric (integer) vector of values in |
x |
vector of strings. |
Only codes in 1:127
make up the ASCII encoding which should be
identical for all R versions, whereas the ‘upper’ half
is often determined from the ISO-8859-1 (aka “ISO-Latin 1)”
encoding, but may well differ, depending on the locale setting, see
also Sys.setlocale
.
Note that 0
is no longer allowed since, R does not allow
\0
aka nul
characters in a string anymore.
AscToChar
returns a vector of the same length as i.
CharToAsc
returns a list of numeric vectors of character length of each string in x.

(x <- CharToAsc("Silvia")) # will be pasted together AscToChar(x) # use strsplit if the single characters are needed strsplit(AscToChar(x), split=NULL) # this would be an alternative, but the latter would be of class raw DecToHex(CharToAsc("Silvia")) charToRaw("Silvia")
