numSummary: Summary Statistics for Numeric Variables

Description

numSummary creates neatly formatted tables of means, standard deviations, coefficients of variation, skewness, kurtosis, and quantiles of numeric variables.

Usage

numSummary(data, 
	statistics=c("mean", "sd", "quantiles", "cv", "skewness", "kurtosis"),
	type=c("1", "2", "3"),
    quantiles=c(0, .25, .5, .75, 1), groups)
    
## S3 method for class 'numSummary':
print(x, ...)

Arguments

data
a numeric vector, matrix, or data frame.
statistics
any of "mean", "sd", "quantiles", "cv" (coefficient of variation --- sd/mean), "skewness", or "kurtosis", defaulting to the first three.
type
definition to use in computing skewness and kurtosis; see the link[e1071]{skewness} and link[e1071]{kurtosis} functions in the e1071 package. The default is "1".
quantiles
quantiles to report; default is c(0, 0.25, 0.5, 0.75, 1).
groups
optional variable, typically a factor, to be used to partition the data.
x
object of class "numSummary" to print.
...
arguments to pass down from the print method.

Value

  • numSummary returns an object of class "numSummary" containing the table of statistics to be reported along with information on missing data, if there are any.
