##### Summary Statistics for Numeric Variables

`numSummary`

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

- Keywords
- misc

##### 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 thee1071 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.

##### See Also

`mean`

, `sd`

, `quantile`

,
`link[e1071]{skewness}`

, `link[e1071]{kurtosis}`

.

##### Examples

```
library(car)
Prestige[1, "income"] <- NA
numSummary(Prestige[,c("income", "education")],
statistics=c("mean", "sd", "quantiles", "cv", "skewness", "kurtosis"))
numSummary(Prestige[,c("income", "education")], groups=Prestige$type)
remove(Prestige)
```
