print.default {base} | R Documentation |
print.default
is the default method of the generic
print
function which prints its argument.
## Default S3 method: print(x, digits = NULL, quote = TRUE, na.print = NULL, print.gap = NULL, right = FALSE, max = NULL, ...)
x |
the object to be printed. |
digits |
a non-null value for digits specifies the minimum
number of significant digits to be printed in values. The default,
NULL , uses getOption(digits) . (For the
interpretation for complex numbers see signif .)
Non-integer values will be rounded down, and only values
greater than or equal to one are accepted.
|
quote |
logical, indicating whether or not strings
(character s) should be printed with surrounding quotes. |
na.print |
a character string which is used to indicate
NA values in printed output, or NULL (see Details) |
print.gap |
a non-negative integer <= 1024,
or NULL (meaning 1), giving the spacing between adjacent
“columns” in printed vectors, matrices and arrays. |
right |
logical, indicating whether or not strings should be right aligned. The default is left alignment. |
max |
a non-null value for max specifies the approximate
maximum number of entries to be printed. The default, NULL ,
uses getOption(max.print) ; see that help page for more
details. |
... |
further arguments to be passed to or from other methods. They are ignored in this function. |
The default for printing NA
s is to print NA
(without
quotes) unless this is a character NA
and quote =
FALSE
, when <NA>
is printed.
The same number of decimal places is used throughout a vector, This
means that digits
specifies the minimum number of significant
digits to be used, and that at least one entry will be encoded with
that minimum number. However, if all the encoded elements then have
trailing zeroes, the number of decimal places is reduced until at
least one element has a non-zero final digit. Decimal points are only
included if at least one decimal place is selected.
Attributes are printed respecting their class(es), using the values of
digits
to print.default
, but using the default values
(for the methods called) of the other arguments.
When the methods package is attached, print
will call
show
for R objects with formal classes if called
with no optional arguments.
If a non-printable character is encountered during output, it is
represented as one of the ANSI escape sequences (\a
, \b
,
\f
, \n
, \r
, \t
, \v
, \\
and
\0
: see Quotes), or failing that as a 3-digit octal
code: for example the UK currency pound sign in the C locale (if
implemented correctly) is printed as \243
. Which characters
are non-printable depends on the locale.
(Because some versions of Windows get this wrong, all bytes with the
upper bit set are regarded as printable on Windows in a single-byte
locale.)
In all locales, the characters in the ASCII range (0x00
to
0x7f
) are printed in the same way, as-is if printable, otherwise
via ANSI escape sequences or 3-digit octal escapes as described for
single-byte locales.
Multi-byte non-printing characters are printed as an escape sequence
of the form \uxxxx
(in hexadecimal).
This is the Unicode point of the character.
It is possible to have a character string in a character vector that
is not valid in the current locale. If a byte is encountered that is
not part of a valid character it is printed in hex in the form
<xx>
and this is repeated until the start of a valid character.
