R: Plotting an SEL object

plot.SEL {SEL} | R Documentation

## Plotting an SEL object

### Description

This function displays a fitted SEL object and displays the expert's cdf or pdf (depending on the `deriv` argument)

### Usage

    ## S3 method for class 'SEL'
    plot(x, ..., type = c("density", "cdf"), deriv,
          points = TRUE, n = 101, xlab="", ylab="", ylim)

### Arguments

`x` | An SEL object.
`...` | Additional arguments to plot function.
`type` | Determines whether to plot the expert's density or cdf (only if `deriv` is missing).
`deriv` | Determines which derivative of the expert's distribution should be plotted. If specified the `type` argument is ignored.
`points` | Logical indicating whether elicited quantiles should be displayed, when displaying the cdf.
`n` | Integer, number of points used for plotting.
`xlab, ylab` | Label of x-axis and y-axis.
`ylim` | Limits of y axis.

### Examples

    # example from O'Hagan et al. (2006)
    x <- c(177.5, 183.75, 190, 205, 220)
    y <- c(0.175, 0.33, 0.5, 0.75, 0.95)

    fit <- SEL(x, y, Delta = 0.05, bounds = c(165, 250))
    plot(fit)
    plot(fit, type = "cdf")
    plot(fit, deriv = 1)
