text_format: Convenient text formatting functionalities

Description

Convenience functions to manipulate and format text.

Usage

text_format(
  text,
  sep = ", ",
  last = " and ",
  width = NULL,
  enclose = NULL,
  ...
)
text_fullstop(text)
text_lastchar(text, n = 1)
text_concatenate(text, sep = ", ", last = " and ", enclose = NULL)
text_paste(text, text2 = NULL, sep = ", ", enclose = NULL, ...)
text_remove(text, pattern = "", ...)
text_wrap(text, width = NULL, ...)

Value

A character string.

Arguments

text, text2

A character string.

sep

Separator.

last

Last separator.

width

Positive integer giving the target column width for wrapping lines in the output. Can be "auto", in which case it will select 90\ default width.

enclose

Character that will be used to wrap elements of text, so these can be, e.g., enclosed with quotes or backticks. If NULL (default), text elements will not be enclosed.

...

Other arguments to be passed to or from other functions.

n

The number of characters to find.

pattern

Character vector. For data_rename(), indicates columns that should be selected for renaming. Can be NULL (in which case all columns are selected). For data_addprefix() or data_addsuffix(), a character string, which will be added as prefix or suffix to the column names. For data_rename(), pattern can also be a named vector. In this case, names are used as values for the replacement argument (i.e. pattern can be a character vector using <new name> = "<old name>" and argument replacement will be ignored then).

Examples

# Add full stop if missing
text_fullstop(c("something", "something else."))

# Find last characters
text_lastchar(c("ABC", "DEF"), n = 2)

# Smart concatenation
text_concatenate(c("First", "Second", "Last"))
text_concatenate(c("First", "Second", "Last"), last = " or ", enclose = "`")

# Remove parts of string
text_remove(c("one!", "two", "three!"), "!")

# Wrap text
long_text <- paste(rep("abc ", 100), collapse = "")
cat(text_wrap(long_text, width = 50))

# Paste with optional separator
text_paste(c("A", "", "B"), c("42", "42", "42"))
