read.jdx

read.jdx.Shimadzu

file name and path of the .jdx file

filename

encoding of the JCAMP-DX file (used by <code><a rd-options="base" href="/link/readLines?package=hyperSpec&version=0.98-20161118&to=base" data-mini-rdoc="base::readLines">readLines</a></code>)

encoding

list with manually set header values

header

index vector indicating which header entries should be tranfered into the
extra data. Usually a character vector of labels (lowercase, without and dashes, blanks,
underscores). If <code>TRUE</code>, all header entries are read.

keys.hdr2data

further parameters handed to the data import function, e.g.<table><tr><td>
<code>xtol</code> </td>
<td> tolerance for checking calculated x values against checkpoints at beginning
 of line, defaults to XFACTOR</td>
</tr><tr><td>
<code>ytol</code> </td>
<td> tolerance for checking Y values against MINY and MAXY, defaults to YFACTOR</td>
</tr></table>

character vector of text values that should be converted to <code>NA</code>

NA.symbols

should hyperSpec objects from multispectra files be collapsed into one
hyperSpec object (if <code>FALSE</code>, a list of hyperSpec objects is returned).

collapse.multi

this is a first rough import function for JCAMP-DX spectra.

Comfortable ways to work with hyperspectral data sets.
I.e. spatially or time-resolved spectra, or spectra with any other kind
of information associated with each of the spectra. The spectra can be data
as obtained in XRF, UV/VIS, Fluorescence, AES, NIR, IR, Raman, NMR, MS,
etc. More generally, any data that is recorded over a discretized variable,
e.g. absorbance = f (wavelength), stored as a vector of absorbance values
for discrete wavelengths is suitable.
