flowJoTrans {flowWorkspace} | R Documentation

## construct the flowJo-type biexponentioal transformation function

### Description

Normally it was parsed from flowJo xml workspace. This function provides the alternate way to construct the flowJo version of logicle transformation function within R.

### Usage

    flowJoTrans(channelRange = 4096, maxValue = 262144, pos = 4.5, neg = 0,
      widthBasis = -10, inverse = FALSE)

### Arguments

`channelRange` | `numeric` the maximum value of transformed data
`maxValue` | `numeric` the maximum value of input data
`pos` | `numeric` the full width of the transformed display in asymptotic decades
`neg` | `numeric` Additional negative range to be included in the display in asymptotic decades
`widthBasis` | `numeric` unkown.
`inverse` | `logical` whether to return the inverse transformation function.

### Examples

    trans <- flowJoTrans()
    data.raw <- c(-1, 1e3, 1e5)
    data.trans <- trans(data.raw)
    round(data.trans)
    inv <- flowJoTrans(inverse = TRUE)
    round(inv(data.trans))
