Corpus Data Frame Printing

Printing and formatting corpus data frames.

# S3 method for corpus_frame
print(x, rows = 20L, chars = NULL, digits = NULL,
      quote = FALSE, na.print = NULL, print.gap = NULL,right = FALSE,
      row.names = TRUE, max = NULL, display = TRUE, ...)

# S3 method for corpus_frame
format(x, chars = NULL, na.encode = TRUE, quote = FALSE,
       na.print = NULL, print.gap = NULL, ..., justify = "none")

Arguments

x	data frame object to print or format.
rows	integer scalar giving the maximum number of rows to print before truncating the output. A negative or missing value indicates no upper limit.
chars	maximum number of character units to display; see utf8_format.
digits	minimal number of significant digits; see print.default.
quote	logical scalar indicating whether to put surrounding double-quotes ('"') around character strings and escape internal double-quotes.
na.print	character string (or NULL) indicating the encoding for NA values. Ignored when na.encode is FALSE.
print.gap	non-negative integer (or NULL) giving the number of spaces in gaps between columns; set to NULL or 1 for a single space.
right	logical indicating whether to right-align columns (ignored for text, character, and factor columns).
row.names	logical indicating whether to print row names, or a character vector giving alternate row names to display.
max	maximum number of entries to print; defaults to getOption("max.print").
display	logical scalar indicating whether to optimize the printing for display, not byte-for-byte data transmission; see utf8_encode.
justify	justification; one of "left", "right", "centre", or "none". Can be abbreviated.
na.encode	logical scalar indicating whether to encode NA values as character strings.
...	further arguments passed to or from other methods.

Details

The "corpus_frame" class is a subclass of "data.frame", overriding the default print and format methods. To apply this class to a data frame, set is class to c("corpus_frame", "data.frame").

Corpus frame printing left-justifies character and text columns, truncates the output, and displays emoji on Mac OS.

Examples

# default data frame printing
x <- data.frame(text = c("hello world", intToUtf8(0x1f638 + 0:3), letters))
print(x)
