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.

Parameters nwl (automatically calculated now) and remove.zerospc (use hy.setOptions (file.remove.emptyspc = TRUE) instead) have been deprecated and removed.
