R: Plot Methods for mefp Objects

plot.mefp {strucchange} | R Documentation

## Plot Methods for mefp Objects

### Description

This is a method of the generic `plot` function for for `"mefp"` objects as returned by `mefp` or `monitor`. It plots the empirical fluctuation process (or a functional thereof) as a time series plot, and includes boundaries corresponding to the significance level of the monitoring procedure.

### Usage

    ## S3 method for class 'mefp'
    plot(x, boundary = TRUE, functional = "max", main = NULL,
        ylab = "Empirical fluctuation process", ylim = NULL, ...)

### Arguments

`x` | an object of class `"mefp"`.
`boundary` | if `FALSE`, plotting of boundaries is suppressed.
`functional` | indicates which functional should be applied to a multivariate empirical process. If set to `NULL` all dimensions of the process (one process per coefficient in the linear model) are plotted.
`main, ylab, ylim, ...` | high-level `plot` function parameters.

### Examples

    df1 <- data.frame(y=rnorm(300))
    df1[150:300,"y"] <- df1[150:300,"y"]+1
    me1 <- mefp(y~1, data=df1[1:50,,drop=FALSE], type="ME", h=1,
                  alpha=0.05)
    me2 <- monitor(me1, data=df1)

    plot(me2)
