Import xy-Data for Supported Formats into R
Description
The function provides access to the underlying xylib to import data for supported file formats
into R. In most cases, only the file path is needed with further arguments to import the data.
The function automatically recognises allowed formats. See rxylib-package for supported formats.
Usage
read_xyData(file, options = "", verbose = TRUE, metaData = TRUE)
Arguments
file |
character (required): path and file to be imported. The argument accepts an |
options |
character (with default): set format options (see rxylib-package) |
verbose |
logical (with default): enables/disables verbose mode |
metaData |
logical (with default): enables/disables the export of metadata |
Value
The functions returns a list of matrices.
Function version
0.3.0

Examples
##load example dataset
file <- system.file("extdata/ExampleSpectrum.CNF", package = "rxylib")
results <- read_xyData(file)
results
##plot xy-spectrum
plot(results,
type = "l",
xlab = "Energy [keV]",
ylab = "Counts",
main = "Thorite - 1800 s")
mtext(side = 3, "Canberra Inspector 1000, 3 x 3 NaI probe")
##plot contour for TL-spectrum
##imported from an XSYG-file
spectrum <- read_xyData(system.file("extdata/TLSpectrum.xsyg", package = "rxylib"))
contour(
x = spectrum$dataset[[1]]$data_block[,1],
y = 1:ncol(spectrum$dataset[[1]]$data_block[,-1]),
z = spectrum$dataset[[1]]$data_block[,-1],
xlab = "Wavelength [nm]",
ylab = "#Channel",
main = "TL Spectrum")
