Write CDF file from chromatogram

Source: R/write_chroms.R
write_cdf.Rd

Exports a chromatogram in ANDI (Analytical Data Interchange) chromatography format (ASTM E1947-98). This format can only accommodate unidimensional data. For two-dimensional chromatograms, the column to export can be specified using the lambda argument. Otherwise, a warning will be generated and the first column of the chromatogram will be exported.

Usage

write_cdf(x, path_out, sample_name, lambda = NULL, force = FALSE)

Arguments

x

A chromatogram in (wide) format.

path_out

The path to write the file.

sample_name

The name of the file.

lambda

The wavelength to export (for 2-dimensional chromatograms). Must be a string matching one the columns in x or the index of the column to export.

force

Whether to overwrite existing files at the specified path. Defaults to FALSE.

Value

No return value. The function is called for its side effects.

Side effects

Exports a chromatogram in ANDI chromatography format (netCDF) in the directory specified by path_out. The file will be named according to the value of sample_name. If no sample_name is provided, the sample_name attribute will be used if it exists.
