Round a value to a defined number of significant digits printing out trailing zeros, if applicable.

Round a value to a defined number of significant digits printing out trailing zeros, if applicable.

signifString(x, ...)

# S3 method for data.frame
signifString(x, ...)

# S3 method for default
signifString(x, digits = 6, sci_range = 6, sci_sep = "e", si_range, ...)

Arguments

x	The number to round
...	Arguments passed to methods.
digits	integer indicating the number of significant digits
sci_range	integer (or Inf) indicating when to switch to scientific notation instead of floating point. Zero indicates always use scientific; Inf indicates to never use scientific notation; otherwise, scientific notation is used when abs(log10(x)) > si_range.
sci_sep	The separator to use for scientific notation strings (typically this will be either "e" or "x10^" for computer- or human-readable output).
si_range	Deprecated, please use sci_range

Value

A string with the value

Details

Values that are not standard numbers like Inf, NA, and NaN are returned as "Inf", "NA", and NaN.
