# plot.fahrmeier_94

##### Plots for `ddhazard`

Plot to illustrate the estimate state space variables from a `ddhazard`

fit

##### Usage

```
# S3 method for fahrmeier_94
plot(x, xlab = "Time", ylab = "Hazard",
type = "cov", plot_type = "l", cov_index, ylim, col = "black",
add = F, do_alter_mfcol = T, level = 0.95, ddhazard_boot, ...)
```

##### Arguments

- x
Result of

`ddhazard`

call- xlab, ylab, ylim, col
Arguments to override defaults set in the function

- type
Type of plot. Currently, only

`"cov"`

is available for plot of the state space parameters- plot_type
The

`type`

argument passed to`plot`

- cov_index
The index (indices) of the state space parameter(s) to plot

- add
`FALSE`

if you want to make a new plot- do_alter_mfcol
`TRUE`

if the function should alter`par(mfcol)`

in case that`cov_index`

has more than one element- level
Level (fraction) for confidence bounds

- ddhazard_boot
Object from a

`ddhazard_boot`

call which confidence bounds will be based on and where bootstrap samples will be printed with a transparent color- ...
Arguments passed to

`plot`

or`lines`

depending on the value of`add`

##### Details

Creates a plot of state variables or adds state variables to a plot with indices `cov_index`

. Pointwise 1.96 std. confidence intervals are provided with the smoothed co-variance matrices from the fit
