R: Plot Ternary Point

ternfoc.point {RFOC} | R Documentation

## Plot Ternary Point

### Description

Add a point to a ternary plot

### Usage

    ternfoc.point(deltaB, deltaP, deltaT)

### Arguments

`deltaB` | angle, degrees
`deltaP` | angle, degrees
`deltaT` | angle, degrees

### Details

Plot point on a Ternary diagram using Froelich's algorithm.

### Value

List

`h` | vector of x coordinates
`v` | vector of y coordinates

### Note

Use Bfocvec(az1, dip1, az2, dip2) to get the deltaB angle.

    Msdr = CONVERTSDR(55.01, 165.65,  29.2   )
     MEC = MRake(Msdr$M)
      MEC$UP = FALSE
       az1 = Msdr$M$az1
      dip1 = Msdr$M$d1
      az2 = Msdr$M$az2
      dip2 = Msdr$M$d2
      BBB = Bfocvec(az1, dip1,  az2,  dip2)
      V = ternfoc.point(BBB$Bdip, Msdr$M$pd, Msdr$M$td )
