JCAMP-DX Import for Shimadzu Library Spectra
this is a first rough import function for JCAMP-DX spectra.
read.jdx(
filename = stop("filename is needed"),
encoding = "",
header = list(),
keys.hdr2data = FALSE,
...,
NA.symbols = c("NA", "N/A", "N.A."),
collapse.multi = TRUE,
wl.tolerance = hy.getOption("wl.tolerance"),
collapse.equal = TRUE

So far, AFFN and PAC formats are supported for simple XYDATA, DATA TABLEs and PEAK TABLEs.
NTUPLES / PAGES are not (yet) supported.
DIF, DUF, DIFDUP and SQZ data formats are not (yet) supported.

JCAMP-DX support is incomplete and the functions may change without notice. See
