write.ctd {oce} | R Documentation

## Write a CTD Data Object as a CSV File

### Description

Writes a comma-separated file containing the data frame stored in the `data` slot of the first argument. The file is suitable for reading with a spreadsheet, or with `read.csv`. This output file will contain some of the metadata in `x`, if `metadata` is `TRUE`.

### Usage

    write.ctd(object, file, metadata = TRUE, flags = TRUE, format = "csv")

### Arguments

`object` | A `ctd` object, i.e. one inheriting from `ctd-class`.
`file` | Either a character string (the file name) or a connection. If not provided, `file` defaults to `stdout()`.
`metadata` | a logical value indicating whether to put some selected metadata elements at the start of the output file.
`flags` | a logical value indicating whether to show data-quality flags as well as data.
`format` | string indicating the format to use. This may be `"csv"` for a simple CSV format, or `"whp"` for the World Hydrographic Program format, described at [1] and exemplified at [2].
