R: Coerce Data Into a Rsk Object

as.rsk {oce} | R Documentation

## Coerce Data Into a Rsk Object

### Description

Create a rsk object.

### Usage

    as.rsk(time, columns, filename = "", instrumentType = "rbr",
      serialNumber = "", model = "", sampleInterval = NA,
      debug = getOption("oceDebug"))

### Arguments

`time` | a vector of times for the data.
`columns` | a list or data frame containing the measurements at the indicated times; see “Details”.
`filename` | optional name of file containing the data.
`instrumentType` | type of instrument.
`serialNumber` | serial number for instrument.
`model` | instrument model type, e.g. `"RBRduo"`.
`sampleInterval` | sampling interval. If given as `NA`, then this is estimated as the median difference in times.
`debug` | a flag that can be set to `TRUE` to turn on debugging.

### Details

The contents of `columns` are be copied into the `data` slot of the returned object directly, so it is critical that the names and units correspond to those expected by other code dealing with `rsk-class` objects. If there is a conductivity, it must be called `conductivity`, and it must be in units of mS/cm. If there is a temperature, it must be called `temperature`, and it must be an in-situ value recorded in ITS-90 units. And if there is a pressure, it must be absolute pressure (sea pressure plus atmospheric pressure) and it must be named `pressure`. No checks are made within `as.rsk` on any of these rules, but if they are broken, you may expect problems with any further processing.

### Value

An object of `rsk-class` `"rsk"`.
