read.txt.Witec: File Import Witec Raman

In hyperSpec: Work with Hyperspectral Data, i.e. Spectra + Meta Information (Spatial, Time, Concentration, ...)

Description

Import Raman Spectra/Maps from Witec Instrument via ASCII files

Usage

scan.txt.Witec(...)

scan.dat.Witec(...)

scan.txt.Witec.Graph(...)

read.txt.Witec(
  file = stop("filename or connection needed"),
  points.per.line = NULL,
  lines.per.image = NULL,
  type = c("single", "map"),
  hdr.label = FALSE,
  hdr.units = FALSE,
  encoding = "unknown",
  ...,
  quiet = TRUE
)

read.dat.Witec(
  filex = stop("filename or connection needed"),
  filey = sub("-x", "-y", filex),
  points.per.line = NULL,
  lines.per.image = NULL,
  type = c("single", "map"),
  encoding = "unknown",
  ...,
  quiet = hy.getOption("debuglevel") < 1L
)

read.txt.Witec.Graph(
  headerfile = stop("filename or connection needed"),
  filex = gsub("Header", "X-Axis", headerfile),
  filey = gsub("Header", "Y-Axis", headerfile),
  type = c("single", "map"),
  encoding = "unknown",
  ...,
  quiet = TRUE
)

Arguments

..., quiet	handed to scan
file	filename or connection to ASCII file
points.per.line	number of spectra in x direction of the map
lines.per.image	number of spectra in y direction
type	type of spectra: single for single spectra (including time series), map for imaging data.
hdr.label	WITec Project exports the spectra names (contain information of map position or number of spectra) within the file.
hdr.units	WITec Project exports the spectra units within the file.
encoding	character encoding, see readLines
filex	filename wavelength axis file
filey	filename intensity file
headerfile	filename or connection to ASCII file with header information
nwl	is deprecated and will be removed soon. Number of wavelengths is calculated automatically.
remove.zerospc	is deprecated and will be removed soon. Use hy.setOptions (file.remove.emptyspc = TRUE) instead.

Details

read.txt.Witec reads Witec ASCII files where the first column gives the wavelength axes and the other columns the spectra. read.dat.Witec reads Witec's ASCII exported data which comes in separate files with x and y data.

Value

a hyperSpec object
