toLatex.numeric

LaTeX or Sweave friendly Formatting of Numbers

Description

Formats real numbers, possibly in scientific notation, with a given number of digits after the decimal point. Output can be used in LaTeX math mode, e.g., for printing numbers in a table, where each number has to be printed with the same number of digits after the decimal point, even if the last digits are zeros.

Usage

## S3 method for class 'numeric'
toLatex(object, digits = format.info(object)[2],
        scientific = format.info(object)[3] > 0, times = "\\cdot", ...)

Arguments

`object`	a numeric vector.
`digits`	number of digits after the decimal point (for the mantissa if `scientific`). The default behaves the same as R's `format()`.
`scientific`	logical indicating if scientific notation `a * 10^k` should be used. The default behaves the same as R's `format()`.
`times`	character string indicating the LaTeX symbol to be used for the ‘times’ sign.
`...`	unused; for compatibility with `toLatex`.

Value

a character vector of the same length as object, containing the formatted numbers.

Note

We use digits for round, i.e., round after the decimal point on purpose, rather than signif()icant digit rounding as used by print() or format().

Examples

xx <- pi * 10^(-9:9)

format(xx)
formatC(xx)

toLatex(xx) #-> scientific = TRUE is chosen
toLatex(xx, scientific=FALSE)

sapply(xx, toLatex)
sapply(xx, toLatex, digits = 2)
