spec_read: Read Spectral Data from Various File Formats

Description

This function reads spectral data from a file, automatically detecting the format and using either `readr` or `readxl` functions. It also sets the specified wavenumber column as the default using `set_spec_wn()`.

Usage

spec_read(file, wn_col, ...)

Value

A tibble containing the spectral data.

Arguments

file

Path to the file to be read.

wn_col

Character. Name of the column containing wavenumber values. This column will be set as the default wavenumber column.

...

Additional arguments passed to `readr::read_delim()`, `readr::read_csv()`, or `readxl::read_excel()`, depending on the file format.

Details

The function automatically determines the file format based on the extension: - `.txt`, `.csv`, `.tsv`, and `.csv2` are read using `readr` functions. - `.xls` and `.xlsx` are read using `readxl::read_excel()`.

If the specified `wn_col` does not exist in the data, an error is returned.

Examples

# \donttest{
  file_path <- system.file("extdata", "CoHAspec.csv", package = "tidyspec")
  df <- spec_read(file_path, wn_col = "Wavenumber")
  check_wn_col() # Verifica se a coluna de wavenumber está definida
# }
