qaProcess.timeflow {flowQ} | R Documentation

## Create QA process of type 'timeflow'

### Description

This function takes a `flowSet` as input and creates all necessary output for a 'timeflow' type QA process. Objects created by this function can be laid out as HTML using `writeQAReport`.

### Usage

    qaProcess.timeflow(set, outdir, cutoff=2, name="time flow",
    sum.dimensions=c(7,7), det.dimensions=c(7,7), pdf=TRUE, ...)

### Arguments

`set` | A `flowSet`.
`outdir` | The directory to which the graphical output is to be saved. If multiple QA processes are to be combined, make sure to use the same directory for all of them.
`cutoff` | The threshold at which the QA criterion is considered to have failed. An absolute value in the timeline deviation score as computed by the `timeLinePlot` function.
`name` | The name of the process used for the headings in the HTML output.
`sum.dimensions, det.dimensions` | The dimensions of the pdf device in inches used for the summary and the detailed plots.
`pdf` | Logical indicating whether to create vectorized versions of images for this quality process. This should be set to `FALSE` if disk space is critical, since the pdf versions of the image consume much more space on the hard drive compared to the bitmap version.
`...` | Further arguments.

### Details

QA processes of type 'timeflow' detect disturbances in the flow of cells over time. These indicate problems with the cell suspension, clogging of the needle or similar issues. If the flow rate is to high, the frequency of measuring cell douplettes increases.

For more details on how to layout `qaProcess` objects to HTML, see `writeQAReport` and `qaReport`.

### Value

An object of class `qaProcess`.
