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
)

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
