This class stores LISST (Laser in-situ scattering and transmissometry) data.
dataAs with all oce objects, the data slot
for lisst objects is a
list containing the main data for the object.
metadataAs with all oce objects, the metadata slot
for lisst objects is a list containing
information about the data or about the object itself.
processingLogAs with all oce objects, the processingLog slot
for lisst 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 lisst objects (see [[<-,lisst-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 lisst
object named lisst may be retrieved in the standard R way. For example,
slot(lisst, "data") and slot(lisst, "metadata") return
the data and metadata slots, respectively. The
[[,lisst-method operator can also be used to access slots,
with lisst[["data"]] and lisst[["metadata"]], respectively.
Furthermore, [[,lisst-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.
One may read lisst objects with read.lisst,
generate them with as.lisst, plot them
with plot,lisst-method, and summarize them with
summary,lisst-method. Elements may be extracted
with [[,lisst-method or replaced with
[[<-,lisst-method.
A users's manual for the LISST-100 instrument is available at the manufacturer's website http://www.sequoiasci.com.
