ggeem_overlay: Add layers of scatter bands, molecular regions and common peaks to EEM plots

Description

This function is a wrapper for geom_eemregions, geom_eempeakloc, geom_eemscatter and can limit the plot extend to the area of the original EEM. Therefore, it is not added using '+' but the plot has to be supplied as an argument.

Usage

ggeem_overlay(
  plot,
  scatter = rep(TRUE, 4),
  regions = TRUE,
  peakloc = TRUE,
  limit = TRUE,
  ...
)

Value

an altered ggplot2

Arguments

plot

the ggplot where the layers are added

scatter

logical vector of size 4 stating the scatter bands to be marked. The order is Raman 1, Raman 2, Rayleigh 1, Rayleigh 2.

regions

logical, whether molecular regions are marked

peakloc

logical, whether common EEM peaks are marked

limit

logical, whether the plot is limited to the original EEM

...

additional arguments passed to geom_eemregions(), geom_eemscatter() and geom_eempeakloc().

Examples

require(tidyr)

eem_list %>%
 eem_extract(eem_names((eem_list))[1], keep = TRUE) %>%
 ggeem() %>%
 ggeem_overlay()
