Plot Chromatogram with Fractions

chrom_plot_fractions(
  data,
  wl_frac = 280,
  fractions = TRUE,
  frac_include = "all",
  frac_labelling = 5,
  frac_text_size = 3,
  frac_text_adjust = 1.3
)

Arguments

data: Datafram containing values.
wl_frac: Wavelengths to show the fractionation scheme for.
fractions: Logical, whether to incude fractions on the plot.
frac_include: Specific fractions to include. Either "all" for all fractions, or a numeric vector of length 2, specifying the limits for the fractions to be included (e.g. c(10, 30) includes fractions from 10 till 30, including both).
frac_labelling: How often to label the fractions. Every $n_th$ fraction is labelled.
frac_text_size: Size of the labels for the fractionation.
frac_text_adjust: `vjust` for the labels for the fractionation.

Value

a ggplot object.
