| encodeString {base} | R Documentation |
encodeString escapes the strings in a character vector in the
same way print.default does, and optionally fits the encoded
strings within a field width.
encodeString(x, width = 0, quote = "", na.encode = TRUE,
justify = c("left", "right", "centre", "none"))
x |
A character vector, or an object that can be coerced to one
by as.character. |
width |
integer: the minimum field width. If NULL or
NA, this is taken to be the largest field width needed for
any element of x. |
quote |
character: quoting character, if any. |
na.encode |
logical: should NA strings be encoded? |
justify |
character: partial matches are allowed. If padding to
the minimum field width is needed, how should spaces be inserted?
justify == "none" is equivalent to width = 0, for
consistency with format.default. |
This escapes backslash and the control characters \a (bell),
\b (backspace), \f (formfeed), \n (line feed),
\r (carriage return), \t (tab), \v (vertical tab)
and \0 (nul) as well as any non-printable characters in a
single-byte locale, which are printed in octal notation
(\xyz with leading zeroes).
(Windows' reporting of printable characters is unreliable, so all
other control characters are regarded as non-printable, and all
characters with codes 32–255 as printable in a single-byte locale.)
See print.default for how non-printable characters are
handled in multi-byte locales.
If quote is a single or double quote any embedded quote of the
same type is escaped. Note that justification is of the quoted
string, hence spaces are added outside the quotes.
A character vector of the same length as x, with the same
attributes (including names and dimensions) but with no class set.
The default for width is different from format.default,
which does similar things for character vectors but without encoding
using escapes.
x <- "ab\bc\ndef"
print(x)
cat(x) # interprets escapes
cat(encodeString(x), "\n", sep="") # similar to print()
factor(x) # makes use of this to print the levels
x <- c("a", "ab", "abcde")
encodeString(x, w = NA) # left justification
encodeString(x, w = NA, justify = "c")
encodeString(x, w = NA, justify = "r")
encodeString(x, w = NA, quote = "'", justify = "r")
