nlines must cover at least one complete spectrum,i.e. nlines
must be at least the number of data points per spectrum. Reasonable
values start at
scan.txt.Renishawscan.txt.Renishaw: the hyperSpec objectscan.txt.Renishaw: The file may be of any file type that can be read by
gzfile (i.e. text, or zipped by gzip, bzip2, xz or
lzma). .zip zipped files need to be read using scan.zip.Renishaw.Renishaw .wxd files are converted to .txt ASCII files by their batch converter. They come in a "long" format with columns (y x | time | z)? wavelength intensity. The first columns depend on the data type.
The corresponding possibilities for the data argument are:
data columns
"spc" wl int
single spectrum
"zspc", "depth" z wl int depth profile
"ts" t wl int time series
"xyspc" y x wl int 2d map
}
This function allows reading very large ASCII files, but it does not work
on files with missing values (NAs are allowed).
If the file is so large that it sould be read in chunks and nspc is
not given, scan.txt.Renishaw tries to guess it by using wc
(if installed).
