## Syncline and Anticline traces

### Description

Syncline and Anticline traces

### Usage

    SynAnticline(x, y, syn = TRUE, spacing = NULL, N = 1, r1 = 1, r2 = 1.2,
     h1 = 0, h2 = 0, endtol = 0.1, REV = FALSE, col = "black", ...)

### Arguments

`spacing` | spacing of points
`N` | number of points
`r1` | x-radius of curled part
`r2` | y-radius of curled part
`h1` | length of first leg
`h2` | length of 2nd leg
`endtol` | indent on either ends
`REV` | reverse direction of x-y
`col` | color of teeth and line
`...` | graphical parameters
