read_mseed: 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"
)

Examples

Run this code


if (FALSE) {
## 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"))
}
