## Plots Profile Likelihoods

### Description

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

### Usage

    ## S3 method for class '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`.

### Value

Produces plots with the profile likelihoods on the current graphics device. No values are returned.
