"\0" gives no warning "unknown escape sequence" (PR#11107)
...C code.
There is no warning about an unknown escape sequence.
(cf. R FAQ 7.37)
# example:
s <- "abc\0def"
s
# --> [1] "abc"
nchar(s)
# --> [1] 3
The "\0" seems to be so fundamental, that it cannot be handled by
any R function, am I right?
E.g., the function escapeBS (package:Hmisc) does not correctly
handle "\0" sequences, that is in contrast to what is stated in its
article ?escapeBS :
"'escapeBS' will escape any backslash '\backslash' in a string.
# example:
library(Hmisc)
escapeBS("abc\0def")
# -->[1] "abc&...
