### Description

Calculates the sum of the column standard devation divided by the sum of the column mean and a small value to avoid dividing by 0 (`eps`)

### Usage

    comb_cv(X, eps = 1e-04)

### Arguments

`X` | data.frame or matrix of numeric data
`eps` | small value to add to the mean to avoid dividing by 0; defaults to 1e-4

### Value

returns the sum of the coefficients of variation for all columns of `X`

### Examples

    comb_cv( data.frame( test1=rep(0,5), test2=c(0.2,0.3,0.35,0.27,0.21) ) )
