These data input functions are deprecated and they will be removed in the next release of hyperspec package. Now functions in package hySpc.read.spe (link) should be used as the alternatives.
Old description:
Import function for WinSpec SPE files (file version up to 3.0). The calibration data (polynome and calibration data pairs) for x-axis are automatically read and applied to the spectra. Note that the y-calibration data structure is not extracted from the file since it is not saved there by WinSpec and is always empty.
read.spe( filename, xaxis = "file", acc2avg = F, cts_sec = F, keys.hdr2data = c("exposure_sec", "LaserWavelen", "accumulCount", "numFrames", "darkSubtracted") ) spe.showcalpoints(filename, xaxis = "file", acc2avg = F, cts_sec = F)
filename | Name of the SPE file to read data from |
---|---|
xaxis | Units of x-axis, e.g., "file", "px", "nm", "energy",
"raman", ...
|
acc2avg | whether to divide the actual data set by the number of
accumulations, thus transforming accumulated spectra to
averaged spectra. WinSpec does not do this automatically, so the
spectral intensity is always proportional to the number of accumulations.
The flag |
cts_sec | whether to divide the actual data set by the exposure time, thus going to count per second unit. |
keys.hdr2data | Which metadata from the file header should be saved to
the |
hyperSpec object
spe.showcalpoints
: Plot the WinSpec SPE file (version 2.5) and show the
calibration points stored inside of it (x-axis calibration)
