binnedCounts {RcmdrMisc}

Binned Frequency Distributions of Numeric Variables

Description

Bins a numeric variable, as for a histogram, and reports the count and percentage in each bin. The computations are done by the hist function, but no histogram is drawn. If supplied a numeric matrix or data frame, the distribution of each column is printed.

Usage

binnedCounts(x, breaks="Sturges", round.percents=2, 
  name=deparse(substitute(x)))

Arguments

x

a numeric vector, matrix, or data frame.

breaks

specification of the breaks between bins, to be passed to the hist function.

round.percents

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

name

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

Value

For a numeric vector, invisibly returns the vector of counts, named with the end-points of the corresponding bins. For a matrix or data frame, invisibly returns NULL
