source_biplot: Create Biplot

In mncube/mxsrquick: What the Package Does (One Line, Title Case)

Description

Create a biplot for group means and standard deviations with an option to shift by trophic discrimination factor means and standard deviations. Function is built for plotting source data

Usage

source_biplot(
  data,
  group,
  var1,
  var2,
  tdf1 = c(mean = 0, sd = 0),
  tdf2 = c(mean = 0, sd = 0),
  x_lab = "",
  y_lab = ""
)

Arguments

data	A data frame
group	Groups of sources to be plotted
var1	X-axis isotope
var2	Y-axis isotope
tdf1	trophic discrimination factor for var 1 entered as tdf1 = c(mean, sd)
tdf2	trophic discrimination factor for var 1 entered as tdf1 = c(mean, sd)
x_lab	X-axis label
y_lab	Y-axis label

Value

Plot

Examples

iso_data <- data.frame(iso_a = c(2.2, 4.4, 3.3, 5.1, 3.4),
iso_b = c(1.6, 3.9, 5.2, 4.2, 3.7),
prot = c("bug", "bug", "bug", "plant", "plant"))
source_biplot(iso_data, prot, iso_a, iso_b, tdf1 = c(2, 1), tdf2 = c(1, 1),
             x_lab = "A", y_lab = "B")
