Import function for WinSpec SPE files (file version 2.5). 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"))read.spe.header(filename)
spe.showcalpoints(filename, xaxis = "file", acc2avg = F, cts_sec = F)
Name of the SPE file to read data from
Units of x-axis, e.g. "file", "px",
"nm", "energy", "raman", ...
read.spe function automatically checks if the x-calibration data are
available and uses them (if possible) to reconstruct the xaxis
in the selected units.
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 @data$averaged is automatically set to TRUE.
whether to divide the actual data set by the exposure time, thus going to count per second unit.
