Details

This method calls on getMetricsXml to communicate with the BSS and obtain an XML reponse. This response is then processed and used to create _Metric objects which are returned as a metricList.

Error returns from the BSS will stop evaluation and throw an error message.

# Open a connection to EarthScope webservices (including the BSS)
iris <- new("IrisClient", debug=TRUE)

starttime <- as.POSIXct("2014-01-24", tz="GMT")
endtime <- as.POSIXct("2014-01-25", tz="GMT")

# Get the metricList
metricList <- getBssMetricList(iris,"AK","PIN","","",starttime,endtime,
                               metricName="sample_mean")
