Description

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 https://ftirsearch.com/features/converters/SPCFileFormat.htm.

Usage

read.spc(filename, keys.hdr2data = FALSE,
    keys.hdr2log = FALSE, keys.log2data = FALSE,
    keys.log2log = FALSE, log.txt = TRUE, log.bin = FALSE,
    log.disk = FALSE, hdr = list(), no.object = FALSE)

Arguments

filename
The complete file name of the .spc file.
keys.hdr2data,keys.log2data
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) of the returned hyperSpec object.

All header fields specified in the .spc file format specif

keys.hdr2log,keys.log2log
deprecated
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? If so, they will be put as raw vectors into the hyperSpec object's log.
hdr
A list with fileheader fields that overwrite the settings of actual file's header.

Use with care, and look into the source code for detailed insight on the elements of this list.

no.object
If TRUE, a list with wavelengths, spectra, labels, log and data are returned instead of a hyperSpec object.

This parameter will likely be subject to change in future - use with care.

Value

  • If the file contains multiple spectra with individual wavelength axes, read.spc returns a list of hyperSpec objects. Otherwise the result is a hyperSpec object.

    read.spc.KaiserMap returns a hyperSpec object with data columns x, y, and z containing the stage position as recorded in the .spc files' log.

Examples

## get the sample .spc files from ftirsearch.com (see above)
# single spectrum
spc <- read.spc ("BENZENE.SPC")
plot (spc)

# multi-spectra .spc file with common wavelength axis
spc <- read.spc ('IG_MULTI.SPC')
spc

# multi-spectra .spc file with individual wavelength axes
spc <- read.spc ("BARBITUATES.SPC")
plot (spc [[1]], lines.args = list (type = "h"))
