# smry: Summary In hydroTSM: Time Series Management, Analysis and Interpolation for Hydrological Modelling

## Description

Extended summary function for numeric objects, with 13 summary statistics.

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16``` ```smry(x, ...) ## Default S3 method: smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...) ## S3 method for class 'zoo' smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...) ## S3 method for class 'Date' smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...) ## S3 method for class 'matrix' smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...) ## S3 method for class 'data.frame' smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...) ```

## Arguments

 `x` a numeric object, vector, matrix or data.frame, for which a summary is desired. `na.rm` a logical value indicating whether 'NA' values should be stripped before the computation proceeds. `digits` numeric, with the amount of decimal places to be included in the result `...` further arguments passed to or from other methods.

## Value

Computed summary statistics are:

 `Min` Minimum `1stQ` First quartile (lower-hinge) `Mean` Mean value `Median` Median `3rdQ` Third quartile ( upper-hinge `Max` Maximum of the input values. `IQR` Interquartile Range. `IQR(x) = quantile(x,3/4) - quantile(x,1/4)` `sd` Standard deviation. It uses 'n-1' as denominator. `cv` Coefficient of variation ( `cv= sd / |mean|` ) `skewness` Skewness (using e1071 package) `kurtosis` Kurtosis (using e1071 package) `n` Total number of elements `NA's` Amount of missing values

## Note

Skewness and Kurtosis are computed with the e1071 package
