FAP Ternary Diagram for Plutonic and Volcanic Rocks

ternary_fap() draws either a static or interactive ternary diagram, in english or spanish. It is a base diagram where data can be plotted.

Usage

ternary_fap(
  output = c("ggplot", "plotly"),
  language = c("en", "es"),
  type = c("plutonic", "volcanic")
)

Arguments

output

The output format: "ggplot" or "plotly" (default is "ggplot")

language

The language to be displayed: "en" for english or "es" for spanish (deafult is "en")

type

The type of volcanic rock: "plutonic" or "volcanic" (default is "plutonic")

Value

FAP ternary diagram for plutonic and volcanic rocks in the desired format (object)

Details

For plotting data on the ggplot object it would be easier if the names of the dataframe are "p", "f", and "a", that way it gets mapped automatically, if not make sure to use "aes(x=p,y=f,z=a)". For plotting on the plotly object the mapping of the new data should be as shown in the example: a = ~f, b = ~p, c = ~a, where a refers to the top ("f"), b refers to the bottom left ("p"), and c refers to the bottom right ("a"). The examples show basic usage and how to add data, which can be more customizable.

Examples

library(ggplot2)
library(plotly)

d = data.frame(f=c(23,40,60),
               p=c(27,50,30),
               a=c(50,10,10))
