histBeadCounts {beadarray} | R Documentation

## Plot numbers of each bead

### Description

Function to plot on a histogram the numbers of each bead type found on an array.

### Usage

    histBeadCounts(BLData, array, main = NULL)

### Arguments

`BLData` | BeadLevelList object
`array` | numeric value giving the array we want to plot for
`main` | specify a title for the plot

\

### Details

It is known that the number of each bead type to be found on an array follows a Poisson distribution with a mean of around 30. This plot helps us to see how well this assumption is met. If too many bead types have less than 30 beads it might indicate a problem with the array and compromise the robustness of the experiment.

We show a Poisson distribution with mean ~50,000 / 1500 on top of the histogram so it can be seen how different the numbers of beads we observe is to how many we expect to see.

### Value

Histogram is plotted.
