Description

Take most prominent columns required for data evaluation first - followed by all other columns.

Usage

order_columns(mfd, col_order = NULL, ...)

Arguments

mfd	data.table with molecular formula data as derived from ume::assign_formulas. Column names of elements/isotopes must match names in the isotope column of ume::masses; values are integers representing counts per formula.
col_order	A list of column names that defines the order of columns of mfd. Default is: cols = c("sample_tag", "sample_id", "file", "file_id", "peak_id", "i_magnitude", "norm_int", "m", "m_cal", "ppm", "nm", "mf", "dbe", "c", "h", "n", "o", "p", "s", "hc", "oc", "nc", "sc", "ai", "z", "kmd") If "cols" is NULL the default order is applied.
...	Additional arguments passed to methods.
