readTwoCol: Read a 2-column whitespace-delimited ASCII record.
In gmsp: Ground Motion Signal Processing
readTwoCol R Documentation
Read a 2-column whitespace-delimited ASCII record.
Description
Time in column 1 (seconds), signal in column 2. No header. Separator
(space or tab) is auto-detected by fread. Trailing all-NA columns
(some providers leave a trailing tab -> phantom column) are dropped.
Usage
readTwoCol(file)
Arguments
file
Path to the file.
Details
OCID extracted from filename. Three known patterns:
SEED-like: NET.STA.LOC.CHA__... -> CHA
CENA: <date>_<time>_NET.STA.CHA_AccTH -> CHA
CLSMD: <X>_acc.txt -> X
Value
LONG data.table(t, OCID, s).
Examples
dir <- tempfile()
dir.create(dir)
file <- file.path(dir, "N_acc.txt")
writeLines(c("0 1", "0.01 2"), file)
readTwoCol(file)
