## Detector Type

### Description

    detector(object) <- value

### Arguments

`object` | object with 'detector' attribute e.g. `traps`
`value` | character string for detector type
`...` | other arguments (not used)

### Details

Valid detector types in version 1.3 are 'single', 'multi', 'proximity', 'count', 'quadratbinary', 'quadratcount' and 'signal'. The detector type is stored as an attribute of a `traps` object. Detector types are mostly described by Efford et al. (2009a,b).
