Description Usage Arguments Details See Also

Create and display diagnostic plots for an evm object. See plot.evmOpt for further details on what is being plotted.

`data`	An object of class `evm`.
`mapping, environment`	ignored
`which`	Which plots to produce. Defaults to `which=1:4`.
`main`	Main titles. Should have length 4.
`xlab`	Labels for x-axes.
`nsim`	Number of simulated datasets to create to form tolerence regions.
`alpha`	Used to compute coverage of pointwise confidence intervals.
`jitter.width`	Used to control the amount of horizontal jittering of points in the plots of the residuals versus covariates (when covariates are in the model). Defaults to `jitter.width=0`.
`ptcol`	Colour for points. Defaults to `ptcol="blue"`.
`span`	Passed to the loess smoother and defaults to `span=2/3`. Sometimes this choice is poor: if the loess smoother looks wrong, try `span=1`.
`col`	Colour for lines. Defaults to `col="light blue"`.
`fill`	Colour for confidence regions. Defaults to `fill="orange"`
`plot.`	Whether or not to display the output. Defaults to `plot.=TRUE`. If the display doesn't have the desired row and column layout, the user should specify `plot.=FALSE`, asign the output to an object, and use `grid.arrange` to display it.
`ncol`	The number of columns wanted in the resulting plot. Defaults to `ncol=2`. This argument is passed into `grid.arrange`.
`nrow`	The number of rows wanted in the resulting plot. Defaults to `nrow=2`. This argument is passed into `grid.arrange`.
`...`	Other arguments passed through to underlying plot functions.

The function attempts to arrange the plots nicely. If the output isn't what was wanted, the function returns the graphs to the user as a list so that the user can use grid.arrange directly. Also, if you have one or more covariates in the model and the loess smoother looks wrong, try setting span=1.
