## Plot Method for `isoreg`

Objects

### Description

The `plot`

and `lines`

method for
**R** objects of class `isoreg`

.

### Usage

```
## S3 method for class 'isoreg'
plot(x, plot.type = c("single", "row.wise", "col.wise"),
main = paste("Isotonic regression", deparse(x$call)),
main2 = "Cumulative Data and Convex Minorant",
xlab = "x0", ylab = "x$y",
par.fit = list(col = "red", cex = 1.5, pch = 13, lwd = 1.5),
mar = if (both) 0.1 + c(3.5, 2.5, 1, 1) else par("mar"),
mgp = if (both) c(1.6, 0.7, 0) else par("mgp"),
grid = length(x$x) < 12, ...)
## S3 method for class 'isoreg'
lines(x, col = "red", lwd = 1.5,
do.points = FALSE, cex = 1.5, pch = 13, ...)
```

### Arguments

`x` |
an |

`plot.type` |
character indicating which type of plot is desired. The first (default) only draws the data and the fit, where the others add a plot of the cumulative data and fit. Can be abbreviated. |

`main` |
main title of plot, see |

`main2` |
title for second (cumulative) plot. |

`xlab` , `ylab` |
x- and y- axis annotation. |

`par.fit` |
a |

`mar` , `mgp` |
graphical parameters, see |

`grid` |
logical indicating if grid lines should be drawn. If
true, |

`do.points` |
for |

`col` , `lwd` , `cex` , `pch` |
graphical arguments for |

`...` |
further arguments passed to and from methods. |

objects.

### Examples

```
require(graphics)
utils::example(isoreg) # for the examples there
plot(y3, main = "simple plot(.) + lines(<isoreg>)")
lines(ir3)
## 'same' plot as above, "proving" that only ranks of 'x' are important
plot(isoreg(2^(1:9), c(1,0,4,3,3,5,4,2,0)), plot.type = "row", log = "x")
plot(ir3, plot.type = "row", ylab = "y3")
plot(isoreg(y3 - 4), plot.type = "r", ylab = "y3 - 4")
plot(ir4, plot.type = "ro", ylab = "y4", xlab = "x = 1:n")
## experiment a bit with these (C-c C-j):
plot(isoreg(sample(9), y3), plot.type = "row")
plot(isoreg(sample(9), y3), plot.type = "col.wise")
plot(ir <- isoreg(sample(10), sample(10, replace = TRUE)),
plot.type = "r")
```
