This class stores data from Argo floats.
dataAs with all oce objects, the data slot
for argo objects is a
list containing the main data for the object.
The key items stored in this slot include equal-length vectors time, longitude, latitude and equal-dimension matrices pressure, salinity, and temperature.
metadataAs with all oce objects, the metadata slot
for argo objects is a list containing
information about the data or about the object itself.
Examples that are of common interest include id, a vector of ID codes for the profiles, and dataMode, a vector of strings indicating whether the profile is in archived mode ("A"), realtime mode ("R"), or delayed mode ("D").
processingLogAs with all oce objects, the processingLog slot
for argo 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 argo objects (see [[<-,argo-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 argo
object named argo may be retrieved in the standard R way. For example,
slot(argo, "data") and slot(argo, "metadata") return
the data and metadata slots, respectively. The
[[,argo-method operator can also be used to access slots,
with argo[["data"]] and argo[["metadata"]], respectively.
Furthermore, [[,argo-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.
An argo object may be read with read.argo or
created with as.argo. Argo data can be gridded to constant
pressures with argoGrid or subsetted with
subset,argo-method. Plots can be made with
plot,argo-method, while summary,argo-method
produces statistical summaries and show produces overviews.
See http://www.argo.ucsd.edu/Gridded_fields.html for some argo-related datasets that may be useful in a wider context.
