### 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 |

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)
```
