name of the plot file(s) to save (e.g. "isospace_plot") |

T/F, save the plot(s) as a pdf? |
plot_save_png |
T/F, save the plot(s) as a png? |
return_obj |
T/F, whether or not to return ggplot object for further modification, defaults to F |
An important detail is that plot_data_two_iso
plots the raw mix data
and adds the TDF to the source data, since this is the polygon that the
mixing model uses to determine proportions. The plotted source means are:
μ_source + μ_discr
The source error bars are +/- 1 standard deviation, calculated as a combination of source and TDF variances:
√{σ^2_source + σ^2_discr}
plot_data_two_iso
looks for 'C', 'N', 'S', and 'O' in the biotracer column
headers and assumes they are stable isotopes, labeling the axes with, e.g.,
expression(paste(delta^13, "C (u2030)",sep="")).
