Import for Thermo Galactic's spc file format These functions allow to import .spc files. A detailed description of the .spc file format is available at

Usage

read_spc_nosubhdr(
  filename,
  keys.hdr2data = c("fexper", "fres", "fsource"),
  keys.hdr2log = c("fdate", "fpeakpt"),
  keys.log2data = FALSE,
  keys.log2log = TRUE,
  log.txt = TRUE,
  log.bin = FALSE,
  log.disk = FALSE,
  hdr = list(),
  nosubhdr = TRUE,
  no.object = FALSE
)

Arguments

filename	The complete file name of the .spc file.
keys.hdr2data, keys.hdr2log, keys.log2data, keys.log2log	character vectors with the names of parameters in the .spc file's log block (log2xxx) or header (hdr2xxx) that should go into the extra data (yyy2data) or into the long.description field of the returned object's log (yyy2log).
log.txt	Should the text part of the .spc file's log block be read?
log.bin, log.disk	Should the normal and on-disk binary parts of the .spc file's log block be read?
hdr	A list with fileheader fields that overwrite the settings of actual file's header.
nosubhdr	Boolean value to decide if the header should be read or not.
no.object	If TRUE, a list with wavelengths, spectra, labels, log and data are returned instead of a hyperSpec object.
