`spec_join()` combines two or more spectral tibbles that share the same wavenumber column. The function performs a full join operation, keeping all wavenumber values from all input tibbles.
Usage
spec_join(..., wn_col = NULL, join_type = "full", suffix = c(".x", ".y"))Arguments
- ...
Two or more tibbles containing spectral data
- wn_col
Character string specifying the wavenumber column name. If NULL, uses the globally set wavenumber column from `set_spec_wn()`.
- join_type
Character string specifying the type of join operation. Options: "full" (default), "inner", "left". See Details.
- suffix
Character vector of length 2 specifying suffixes to add to non-wavenumber columns when there are naming conflicts. Default: c(".x", ".y")
Details
Join types: - "full": Keep all wavenumber values from all tibbles (default) - "inner": Keep only wavenumber values present in all tibbles - "left": Keep wavenumber values from the first tibble
The function will show warnings about the wavenumber column being used (similar to other tidyspec functions) and will handle missing values appropriately.
Examples
if (FALSE) { # \dontrun{
# Set wavenumber column
set_spec_wn("Wavenumber")
# Join two spectral datasets
joined_data <- spec_join(CoHAspec, other_spec_data)
# Join multiple datasets with inner join
joined_data <- spec_join(spec1, spec2, spec3, join_type = "inner")
# Specify wavenumber column explicitly
joined_data <- spec_join(spec1, spec2, wn_col = "Wavenumber")
} # }
