scan.txt.Witec: File Import Witec Raman

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
)

Value

a hyperSpec object

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

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.
