sprintf_dm: Format numeric values as strings

In ggpmisc: Miscellaneous Extensions to 'ggplot2'

Format numeric values as strings

Description

Using sprintf flexibly format numbers as character strings encoded for parsing into R expressions or using LaTeX or markdown notation.

Usage

sprintf_dm(fmt, ..., decimal.mark = getOption("OutDec", default = "."))

value2char(
  value,
  digits = Inf,
  format = "g",
  output.type = "expression",
  decimal.mark = getOption("OutDec", default = ".")
)

Arguments

fmt	character as in sprintf().
...	as in sprintf().
decimal.mark	character If NULL or NA no substitution is attempted and the value returned by sprintf() is returned as is.
value	numeric The value of the estimate.
digits	integer Number of digits to which numeric values are formatted.
format	character One of "e", "f" or "g" for exponential, fixed, or significant digits formatting.
output.type	character One of "expression", "latex", "tex", "text", "tikz", "markdown".

Details

These functions are used to format the character strings returned, which can be used as labels in plots. Encoding used for the formatting is selected by the argument passed to output.type, thus, supporting different R graphic devices.
