subset.oce: Subset an oce object

Description

Subset an oce object

Usage

## S3 method for class 'oce}(x, subset, indices=NULL, debug=getOption("oceDebug"), \dots)':
subsetundefined
x{an oce object.}
  subset{a condition to be applied to the data portion of
    x.  See Details.}
  indices{list of station indices (used only for section objects).}
  debug{a flag that turns on debugging.  Set to 1 to get a
    moderate amount of debugging information, or to 2 to get more.} 
  ...{ignored.}
This function is somewhat analogous to
    subset.data.frame, but it is more limited because it works by
    individualized inspection of x depending on its class.  Only one
    independent variable may be used in subset in any call to the
    function, which means that repeated calls will be necessary to, subset
    based on more than one independent variable (e.g. time and distance).
A new oce object.
window.oce provides a simpler, but less powerful,
  way to subset data.
