ASCIIfy {gtools} | R Documentation |
Convert Characters to ASCII
Description
Convert character vector to ASCII, replacing non-ASCII characters with single-byte (‘\x00’) or two-byte (‘\u0000’) codes.
Usage
ASCIIfy(x, bytes = 2, fallback = "?")
Arguments
x |
a character vector, possibly containing non-ASCII characters. |
bytes |
either |
fallback |
an output character to use, when input characters cannot be converted. |
Value
A character vector like x
, except non-ASCII characters have been
replaced with ‘\x00’ or ‘\u0000’ codes.
Note
To render single backslashes, use these or similar techniques:
write(ASCIIfy(x), "file.txt") cat(paste(ASCIIfy(x), collapse="\n"), "\n", sep="")
The resulting strings are plain ASCII and can be used in R functions and datasets to improve package portability.
