# Plot model fits (observed and fitted) and the residuals for a row or column of an mmkin object

Source:`R/plot.mmkin.R`

`plot.mmkin.Rd`

When x is a row selected from an mmkin object (`[.mmkin`

), the
same model fitted for at least one dataset is shown. When it is a column,
the fit of at least one model to the same dataset is shown.

## Arguments

- x
An object of class

`mmkin`

, with either one row or one column.- main
The main title placed on the outer margin of the plot.

- legends
An index for the fits for which legends should be shown.

- resplot
Should the residuals plotted against time, using

`mkinresplot`

, or as squared residuals against predicted values, with the error model, using`mkinerrplot`

.- ylab
Label for the y axis.

- standardized
Should the residuals be standardized? This option is passed to

`mkinresplot`

, it only takes effect if`resplot = "time"`

.- show_errmin
Should the chi2 error level be shown on top of the plots to the left?

- errmin_var
The variable for which the FOCUS chi2 error value should be shown.

- errmin_digits
The number of significant digits for rounding the FOCUS chi2 error percentage.

- cex
Passed to the plot functions and

`mtext`

.- rel.height.middle
The relative height of the middle plot, if more than two rows of plots are shown.

- ymax
Maximum y axis value for

`plot.mkinfit`

.- ...
Further arguments passed to

`plot.mkinfit`

and`mkinresplot`

.

## Details

If the current plot device is a `tikz`

device, then
latex is being used for the formatting of the chi2 error level.

## Examples

```
# \dontrun{
# Only use one core not to offend CRAN checks
fits <- mmkin(c("FOMC", "HS"),
list("FOCUS B" = FOCUS_2006_B, "FOCUS C" = FOCUS_2006_C), # named list for titles
cores = 1, quiet = TRUE, error_model = "tc")
#> Warning: Optimisation did not converge:
#> iteration limit reached without convergence (10)
plot(fits[, "FOCUS C"])
plot(fits["FOMC", ])
plot(fits["FOMC", ], show_errmin = FALSE)
# We can also plot a single fit, if we like the way plot.mmkin works, but then the plot
# height should be smaller than the plot width (this is not possible for the html pages
# generated by pkgdown, as far as I know).
plot(fits["FOMC", "FOCUS C"]) # same as plot(fits[1, 2])
# Show the error models
plot(fits["FOMC", ], resplot = "errmod")
# }
```
