read_mseed: Read mseed files.

In coffeemuggler/eseis: Environmental Seismology Toolbox

Read mseed files.

Description

This function reads mseed files. If append = TRUE, all files will be appended to the first one in the order as they are provided. In the append-case the function returns a either a list with the elements signal, time, meta and header or a list of the class eseis (see documentation of aux_initiateeseis()). If append = FALSE and more than one file is provided, the function returns a list of the length of the input files, each containing the above elements.

The mseed data format is read using the function readMiniseedFile from the package IRISSeismic.

Usage

read_mseed(
  file,
  append = TRUE,
  signal = TRUE,
  time = TRUE,
  meta = TRUE,
  header = TRUE,
  eseis = TRUE,
  type = "waveform"
)

Arguments

file	Character vector, input file name(s), with extension.
append	Logical value, option to append single files to one continuous file, keeping only the hedaer information of the first file, default is TRUE.
signal	Logical value, option to import the signal vector, default is TRUE.

meta	Logical value, option to append the meta data part, default is TRUE.
header	Logical value, option to append the header part, default is TRUE.

Examples

## Not run: 
## read mseed file with default options
x <- read_mseed(file = "input.miniseed")

## read mseed file, only signal trace, not as eseis object
x <- read_mseed(file = "input.miniseed", 
                time = FALSE, 
                meta = FALSE, 
                header = FALSE, 
                eseis = FALSE)
                
## read more than one mseed files and append traces
x <- read_mseed(file = c("input_1.miniseed", "input_2.miniseed"))

## End(Not run)
