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 |
name |
name for the variable; only used for vector argument |
max.values |
maximum number of unique values (default is the smallest of
twice the square root of the number of elements in |
Value
For a numeric vector, invisibly returns the table of counts.
For a matrix or data frame, invisibly returns NULL
