discreteCounts

Frequency Distributions of Numeric Variables

Description

Computes the frequency and percentage distribution of a descrete numeric variable or the distributions of the variables in a numeric matrix or data frame.

Usage

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

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.

Value

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