oce (version 0.4-1)

pressure: Extract pressure, salinity, or temperature from an oce object

Description

Extract pressure, salinity, or temperature from an oce object

Usage

pressure(x, time)
  salinity(x, time)
  sigmaTheta(x, time)
  temperature(x, time)
  latitude(x, time)
  longitude(x, time)
  time(x, time)
  elevation(x, time)

Arguments

x

an oce object.

time

optional indication of times to which to interpolate. This may be a vector of POSIXt times, or an oce object that contains a vector of POSIXt times.

Value

• A vector containing the indicated variable. For a ctd object, the returned value corresponds directly to the vector x$data$pressure (etc.), but for a section object, the returned value is built by stringing together the values of the indicate variable, station by station.

concept

data extraction

Details

This is a convenience function that isolates the user from the details of storage.

Examples

library(oce)
  data(ctd)
  cat("Average ctd temperature:", mean(temperature(ctd), na.rm=TRUE), "")
  data(a03)
  plot.TS(as.ctd(salinity(a03),temperature(a03),pressure(a03)))
