This function is used by the main function of the package benford to extract the leading digits of the data.

Usage

extract.digits(data, number.of.digits = 2,
               sign="positive", second.order = FALSE, discrete=TRUE, round=3)

Arguments

data
a numeric vector.
number.of.digits
how many first digits to analyse .
sign
The default value for sign is "positive" and it analyzes only data greater than zero. There are also the options "negative" and "both" that will analyze only negative values or both positive and negative values of the data, respectively. For large
second.order
If TRUE, the function will extract the first digits of the second order distribution.
discrete
Most real data - like population numbers or accounting data - are discrete, so the default is TRUE. This paramater sets rounding to the differences of the ordered data to avoid floating point number errors in the second order distribution, that us
round
it defines the number of digits that the rounding will use if discrete = TRUE and second.order = TRUE.

Value

  • A data.frame with the data and the first digits.
