Geochem facet labelers

label_geochem(
  labels,
  units = character(0),
  default_units = NA_character_,
  geochem_facet = 1,
  renamers = c(`^d([0-9]+)([HCNOS])$` = "paste(delta ^ \\1, \\2)", `^210Pb$` =
    "paste({}^210, Pb)", `^Pb210$` = "paste({}^210, Pb)"),
  multi_line = TRUE
)

Arguments

labels: A data.frame of facet label values
units: A named list of values = unit
default_units: The default units to apply
geochem_facet: Which facet to apply formatting
renamers: Search and replace operations to perform in the form search = replace. Replace text can (should) contain backreferences, and will be parsed as an expression (see plotmath). Use NULL to suppress renaming.
multi_line: See label_parsed

Value

A ggplot2::labeller()
