IRISMustangMetrics (version 2.4.6)

MultipleTimeValueMetric-class: Class "MultipleTimeValueMetric"

Description

A container for metrics consisting of a vector of POSIXct datetimes. This information is used to create XML that is then submitted to the MUSTANG Backend Storage System (BSS).

Objects from the Class

Objects can be created by calls of the form:

new("MultipleTimeValueMetric", snclq, starttime, endtime, metricName, values)

Lists of MultipleTimeValueMetric objects are returned by various metrics functions in this package.

Slots

snclq:

Object of class "character": SNCLQ identifier.

metricName:

Object of class "character": Name of the metric.

elementName:

Object of class "character": Name of the datetime element (default="t").

starttime:

Object of class "POSIXct": Start time.

endtime:

Object of class "POSIXct": End time.

values:

Object of class "POSIXct": Datetime values.

valueStrings:

Object of class "character": String representations of the datetime values.

quality_flag:

Object of class "numeric": Quality flag.

quality_flagString:

Object of class "character": String representation of quality flag.

# get the upDownTimes with a minimum signal length and minimum gap (secs)
upDownTimes <- getUpDownTimes(st, min_signal=30, min_gap=60)
  
# Create and return a MultipleTimeValue metric from the upDownTimes
m <- new("MultipleTimeValueMetric", snclq=snclq,
         starttime=starttime, endtime=endtime,
         metricName="up_down_times", values=upDownTimes)

# Show the results
