convert2Rseis: Convert Seismic data to RSEIS

In RSEIS: Seismic Time Series Analysis Tools

Convert Seismic data to RSEIS

Description

Convert Seismic in SAC or SEGY format to RSEIS native format.

Usage

convert2Rseis(FLS, NEWDIR = ".", kind = 1, Iendian = "little", BIGLONG =
FALSE, NEWsta = "", NEWcomp = "")

Arguments

FLS	array of File names
NEWDIR	Destination directory path
kind	an integer 1, 2, 3; 0=R(DAT) , 1 = segy, 2 = sac, 3 = AH.
Iendian	Endian-ness of the data: 1,2,3: "little", "big", "swap". Default = 1 (little)
BIGLONG	logical, TRUE=long=8 bytes
NEWsta	character vector, stations associated with the vector of files
NEWcomp	character vector, component name associated with the vector of files

Details

Converts the data to R format so it can be loaded with the load command. After this conversion, files should be loaded in subsequent calls by using kind=0.

Value

Side effects - creates new files on local system

Note

JGET.seis extracts digital seismic data from binary files stored in the file system. The program uses readBin for I/O and passes data back to R. Currently SAC, SEGY formats are installed but it is easy to extend. AH format is available for LINUX systems, but there were problems compiling in WINDOWS and MACOS so this feature was removed. A filter for mseed format is currently being developed.

Examples

Iendian = .Platform$endian
data(GH)

##########  create some SAC files:
apath = tempdir()
J =  rseis2sac(GH, sel = 1:5, path = apath, BIGLONG =FALSE )
####  get SAC file file names:
Lname  <-  list.files(path=J , pattern='SAC', full.names=TRUE)

#####   convert each file to a saved RSEIS file, saved in apath
####  reading in SAC files, kind=2
convert2Rseis(Lname, NEWDIR = apath, kind = 2, Iendian = Iendian, BIGLONG =
FALSE )
####  check if files are there
list.files(path=apath)
