Description

A Trace object containing a seismic trace -- a continuous timeseries.

Objects from the Class

Objects occupy the traces slot of a Stream-class object and are typically populated by calls to getDataselect.

Examples

# Open a connection to IRIS DMC webservices
iris <- new("IrisClient")

# Set the starttime and endtime
starttime <- as.POSIXct("2012-01-24", tz="GMT")
endtime <- as.POSIXct("2012-01-25", tz="GMT")

# Get the waveform
st <- getDataselect(iris,"AK","PIN","","VEA",starttime,endtime)

# Get the first trace and generate some statistics
tr1 <- st@traces[[1]]
min(tr1)
median(tr1)
mean(tr1)
max(tr1)
sd(tr1)
rms(tr1)
rmsVariance(tr1)
