fhStart {flowPloidy} | R Documentation

## Calculate the where to start analysis for a `FlowHist` histogram

### Description

We exclude the first five bins at the outset (as part of the function `setBins`. For some flow cytometers, these values contain very high spikes that are an artifact of compensation, and are not useful data.

### Usage

    fhStart(intensity)

### Arguments

`intensity` | numeric, the fluorescence intensity channel bins

### Details

After that, we call `fhStart` to skip to the highest value in the first 10 non-zero bins, and ignore everything below that. The motivation here is the same - to get out beyond the noisy bins and into the actual data we're trying to fit.

### Value

an integer, the index of the first intensity element to include in the actual model fitting. That is, everything from `startBin` to the end of `intensity` gets fit in the model, everything below `startBin` is ignored.
