oce (version 0.2-1)

ptr: ptr (pressure-temperature) dataset

Description

A sample ptr file, created by ptr <- read.oce("/data/archive/sleiwex/2008/moorings/m08/pt/rbr_011855/manufacturer/pt_rbr_011855.dat", by=600) patm <- ptPatm(ptr)[4] ptr$data$ts$pressure <- ptr$data$ts$pressure - patm ptr <- historyAppend(ptr, "subtract atmospheric pressure") ptr <- window(ptr, start=as.POSIXct("2008-06-26",tz="UTC"), end=as.POSIXct("2008-06-27",tz="UTC")) save(ptr, file="ptr.rda") (which uses a file not supplied with this package).

Note that the name of this object is an exception to the usual in the oce package, in which the name of the example matches the object type. This is because the name "pt" is already used for a function relating to the "t" distribution.

Usage

data(ptr)

source

The SLEIWEX experiment.
