discreteCounts: Frequency Distributions of Numeric Variables

Description

Frequency Distributions of Numeric Variables

Usage

discreteCounts(
  x,
  round.percents = 2,
  name = deparse(substitute(x)),
  max.values = min(round(2 * sqrt(length(x))), round(10 * log10(length(x))), 100)
)

Value

For a numeric vector, invisibly returns the table of counts. For a matrix or data frame, invisibly returns NULL

Arguments

x

a discrete numeric vector, matrix, or data frame.

round.percents

number of decimal places to round percentages; default is 2.

name

name for the variable; only used for vector argument x.

max.values

maximum number of unique values (default is the smallest of twice the square root of the number of elements in x, 10 times the log10 of the number of elements, and 100); if exceeded, an error is reported.
