argo_pivot_longer: Transform Argo data to variable-long format
In ArgoCanada/argodata: Locate, Download, and Read Argo Ocean Float Data

Description Usage Arguments Value Examples

Whereas the variable-wide format returned by most Argo read and load functions are useful, some processing and plotting algorithms need data in a variable-long form, where the variable name is assigned to a column whose value is used to identify the measurement represented by each row.

1	argo_pivot_longer(tbl, id_cols)

`tbl`	An Argo table with paired value/qc/adjusted columns, likely from `argo_prof_levels()` or `argo_traj_measurement()`.
`id_cols`	A vector of column names used to identify each row in the output using `dplyr::select()` syntax.

A tibble::tibble() with columns id_cols, variable, value, value_qc, value_adjusted, value_adjusted_qc, and value_adjusted_error.
