# plot.proflik

##### Plots Profile Likelihoods

This function produces plots of the profile likelihoods computed by
the function `proflik`

.

##### Usage

```
# S3 method for proflik
plot(x, pages = c("user", "one", "two"), uni.only, bi.only,
type.bi = c("contour", "persp"), conf.int = c(0.90, 0.95),
yaxis.lims = c("conf.int", "as.computed"),
by.col = TRUE, log.scale = FALSE, use.splines = TRUE,
par.mar.persp = c(0, 0, 0, 0), ask = FALSE, …)
```

##### Arguments

- x
an object of the class

`proflik`

, typically an output of the function`proflik`

.- pages
specify how the plots will be arranged in the graphics device. The default option,

`"user"`

, uses the current graphical parameters. The option`"one"`

places all the profiles in the same page and the option`"two"`

places the univariate profiles in one page and the bivariate profiles in a second page.- uni.only
only 1-D profiles are plotted even if the object contains results about the 2-D profiles.

- bi.only
only 2-D profile are plotted even if the object contains results about the 1-D profiles.

- type.bi
Type of plot for the 2-D profiles. Options are

`"contour"`

for contour plot (the default) and`"persp"`

for perspective plot.- conf.int
a vector with numbers in the interval \([0,1]\) specifying levels of the (approximated) confidence intervals. Defaults corresponds to the levels 90% and 95%.

- yaxis.lims
defines the lower limits for the y-axis in the 1-D plots. If

`"conf.int"`

the limit is determined by the level of the confidence interval (the default) otherwise will be determined by the smallest computed value.- by.col
logical, If

`TRUE`

the plots are arranged by columns in a multiple graphics device.- log.scale
plots the x-axis in the logarithmic scale. Defaults to

`FALSE`

.- use.splines
logical. If

`TRUE`

(the default) the function`spline`

is used to interpolate between the points computed by`proflik`

.- par.mar.persp
graphical parameters to be used with

`persp`

plots. For more details see`par`

.- ask
logical. Defines whether or not the user is prompted before each plot is produced.

- …
additional arguments to be passed to the functions

`plot`

,`contour`

and/or`persp`

.
