Convert spectral data files to csv files

lr_convert_tocsv(
  where = NULL,
  ext = "txt",
  decimal = ".",
  sep = NULL,
  subdir = FALSE,
  cores = NULL,
  ignore.case = TRUE,
  overwrite = FALSE
)

Arguments

where

Folder in which files are located (defaults to current working directory).

ext

File extension to be searched for, without the "." (defaults to txt). You can also use a character vector to specify multiple file extensions.

decimal

Character to be used to identify decimal plates (defaults to .).

sep

Column delimiting characters to be considered in addition to the default (which are: tab, space, and ";")

subdir

Should subdirectories within the where folder be included in the search? (defaults to FALSE).

cores

deprecated. See future::plan() for more details on how to customise your parallelisation strategy.

ignore.case

Should the extension search be case insensitive? (defaults to TRUE)

overwrite

logical. Should the function overwrite existing files with the same name? (defaults to FALSE).

Value

Convert input files to csv and invisibly return the list of created file paths

Details

You can customise the type of parallel processing used by this function with the future::plan() function. This works on all operating systems, as well as high performance computing (HPC) environment. Similarly, you can customise the way progress is shown with the progressr::handlers() functions (progress bar, acoustic feedback, nothing, etc.)

Warning

This step loses all metadata associated to the spectra. This metadata is critical to ensure reproducibility. We recommended you use lr_get_metadata() to extract this information from your raw data.
