getCutOff {twoddpcr} | R Documentation

## Find the standard deviation of droplets (in a given class) multipied by a given constant.

### Description

For a specified class, take a data frame of droplet amplitudes and compute the standard deviation multiplied by a level of accuracy.

### Usage

    getCutOff(droplets, cl, level = 3, classCol = "class")

### Arguments

`droplets` | A data frame of droplets with "Ch1.Amplitude" and "Ch2.Amplitude" columns, as well as a class column (see classCol).
`cl` | The class to focus on. Typically one of "NN", "PN", "NP" and "PP".
`level` | A constant by which we will multiply the standard deviation. Defaults to 5.
`classCol` | The column (name or number) from 'droplets' representing the class.

### Value

A list with named elements 'ch1' and 'ch2', each giving the error bound for the corresponding channel. If the number of droplets is either 0 or 1, return list(ch1=0, ch2=0) to avoid any errors. Otherwise, return level * (sd of the droplets in each channel).
