descriptive.table: Table of Descriptives

In Deducer: A Data Analysis GUI for R

Description

Table of descriptive statistics, possibly stratified

Usage

descriptive.table(vars,
	strata,
	data,
	func.names = c("Mean","St. Deviation","Median",
		"25th Percentile","75th Percentile",
		"Minimum","Maximum","Skew","Kurtosis","Valid N"),
	func.additional)

Arguments

vars	A variable or data.frame containing variables on which to run descriptive statistics.
data	The data frame in which vars is evaluated
strata	A variable or data.frame containing variables on which to stratify
func.names	A character vector of built-in statistics
func.additional	A named list of functions. Each function should take a numeric vector as its argument, and return a single value

Value

Returns a list of matrix objects containing descriptive information on all variables in dat. One for each level or combination of levels in strata.

Examples

data(mtcars)
##means and standard deviations
descriptive.table(vars = d(mpg,hp),data= mtcars,
	func.names =c("Mean","St. Deviation","Valid N"))
##stratifying by cyl
descriptive.table(vars = d(mpg,hp) ,
	strata = d(cyl),data= mtcars,
	func.names =c("Mean","St. Deviation","Valid N"))
	
	
func.list=list(mean.deviance=function(x) mean(abs(x-mean(x))))

##Adding deviance as a statistic
descriptive.table(vars = d(mpg,hp) ,
	strata = d(cyl),data= mtcars,
	func.names =c("Mean","St. Deviation","Valid N"),func.additional=func.list)
