data |
a tibble containing the following column names: "HtoC" and "OtoC" |
plot_title |
a character string containing the sample name (default = none) |
The area above the horizontal line at H/C = 1.5 is designated as the aliphatic region in accordance with D'Andrilli et al. 2015 and Lv et al. 2017. The area below the diagonal line from H/C = 1.1 is designated as the aromatic region based on a modified aromaticity index >= 0.5 in accordance with Koch & Dittmar 2006.
