eseis (version 0.7.3)

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.

Examples

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,
