R: Get azimuthal particle motion

GAZI {RSEIS} | R Documentation

## Get azimuthal particle motion

### Description

Do particle motion analysis

### Usage

    GAZI(ADAT, dt = 1, ex = seq(0, 100),
    comp = c(4, 5, 6), sta = "ZZZ", az = 0,
    len = 50, shift = 10, prev = 1, fileid = "", picks = NA, labs = NA)

### Arguments

`ADAT` | Matrix of 3 component seismic data
`dt` | delta T (s)
`ex` | x-axis vector
`comp` | component names
`sta` | station name
`az` | azimuth of station orientation
`len` | length of time series
`shift` | amount to shift per window
`prev` | length of buffer at beginning of trace
`fileid` | character string to put on plot
`picks` | arrival times for annotation
`labs` | labels for arrival times for annotation

### Value

list(aex=aex[1:jall], rateig=rateig[1:jall], aaz=aaz[1:jall], ai=ai[1:jall], figaz=figaz, azpar=azpar, incpar=incpar )

### Examples

    data("GH")

    temp  <-  cbind(GH$JSTR[[4]], GH$JSTR[[5]], GH$JSTR[[6]])

    pmolabs <- c("Vertical", "North", "East")

     G   <-  GAZI(temp, dt =GH$dt[4]  , comp = pmolabs, sta = GH$STNS[4] ,
    az = 0, len =75, shift = 10, prev = 1)
