print.default

R Base 3.6.2

print.default is the default method of the generic print function which prints its argument.

Syntax

# S3 method for default
print(x, digits = NULL, quote = TRUE,
      na.print = NULL, print.gap = NULL, right = FALSE,
      max = NULL, useSource = TRUE, &#8230;)

Arguments

Parameter	Description
`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 1 and no greater than 22 are accepted.
`quote`	logical, indicating whether or not strings (characters) 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 \(\le 1024\), 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.
`useSource`	logical, indicating whether to use source references or copies rather than deparsing language objects. The default is to use the original source if it is available.
`…`	further arguments to be passed to or from other methods. They are ignored in this function.

Details

The default for printing NAs 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. Option width controls the printing of ve

Example

# NOT RUN {
pi
print(pi, digits = 16)
LETTERS[1:16]
print(LETTERS, quote = FALSE)

M <- cbind(I = 1, matrix(1:10000, ncol = 10,
                         dimnames = list(NULL, LETTERS[1:10])))
utils::head(M)        # makes more sense than
print(M, max = 1000)  # prints 90 rows and a message about omitting 910
# }
