This class stores ``Ruskin'' data, from RBR [1].
dataAs with all oce objects, the data slot
for rsk objects is a
list containing the main data for the object.
metadataAs with all oce objects, the metadata slot
for rsk objects is a list containing
information about the data or about the object itself.
processingLogAs with all oce objects, the processingLog slot
for rsk objects is a
list with entries describing the creation and evolution
of the object. The contents are updated by various oce functions to
keep a record of processing steps. Object summaries and
processingLogShow both display the log.
Although the [[<- operator may permit modification of the contents
of rsk objects (see [[<-,rsk-method),
it is better to use oceSetData
and oceSetMetadata, because that will save an entry
in the processingLog to describe the change.
The full contents of the data and metadata slots of a rsk
object named rsk may be retrieved in the standard R way. For example,
slot(rsk, "data") and slot(rsk, "metadata") return
the data and metadata slots, respectively. The
[[,rsk-method operator can also be used to access slots,
with rsk[["data"]] and rsk[["metadata"]], respectively.
Furthermore, [[,rsk-method can be used to retrieve
named items (and potentially some derived items) within the
metadata and data slots, the former taking precedence
over the latter in the lookup. It is also possible
to find items more directly, using oceGetData and
oceGetMetadata, but this cannot retrieve derived items.
A rsk object may be read with read.rsk or created with
as.rsk. Plots can be made with plot,rsk-method, while
summary,rsk-method produces statistical summaries and show
produces overviews. If atmospheric pressure has not been removed from the
data, the functions rskPatm may provide guidance as to its value;
however, this last function is no equal to decent record-keeping at sea.
